Good morning, or good afternoon, ladies and gentlemen, and welcome to the OceanaGold 2017 second quarter results webcast and conference call. [Operator Instructions].
This call is being recorded on July 27, at 5:30 p.m. Eastern standard Time.
I would now like to turn the conference over to Jeffrey Sansom. Please go ahead.
Jeffrey Sansom
Hello, everybody, and welcome to the OceanaGold Second Quarter two017 financial and operating results call and webcast. Thanks for joining us today.
My name is Jeffrey Sansom from the Investor Relations team at OceanaGold. On the call with me today in Melbourne areMick Wilkes, President and CEO.
I'd like to introduce Scott McQueen, Chief Financial Officer; we have Michael Holmes, Chief Operating Officer; and Edward Sit Woon, Corporate Controller. In Toronto, we have Sam Pazuki, Vice President of Investor Relations.
Before we proceed, know that all references in this presentation that you're about to hear adhere to international financial reporting standards, and all financial figures are denominated in US dollars, unless otherwise stated. Also note that the transmission contains forward-looking statements, which by their very nature, are subject to some degree of uncertainty.
I will now hand it over to Mick Wilkes, to begin the presentation.
Michael Wilkes
Thank, Jeff, and welcome, everybody, to our second quarter webcast. Happy to have you with us.
I'll start on Page 3 with the summary of our results looking at production first of all, a steady quarter, 125,000 ounces and 272,000 ounces for the first half, putting us on track to achieve our guidance for the full year. Sales are stronger on the back of some increased drawdown of inventories of concentrated sales in the Philippines, in particular.
Copper production and sales were both strong in the first half, having produced in total around about 10,000 tonnes copper. And of course all sustaining cost is good year to date, about $600 per ounce, putting us in line and on track for our full year guidance.
Group revenues $333 million, a decent gold price of $1244 and an improved price of $257. The -- and the net profit for the half year is $61 million after extra ordinary items, so $25 million profit in the second quarter.
Turning on to page 4. And just to highlight the continued strong performance of the company in terms of financial metrics.
Our EBITDA for the first half in terms of margin is almost 56%. Our earnings per adjusted for abnormal items like impairment is $0.13 per share and a cash flow before per share of $0.28.
And for the quarter, similar figures, a little bit lower than then second -- the first quarter. Our EBITDA is 50% margin and adjusted earnings per share of $0.04 per share.
As a result of those strong financial metrics, we continue to have strong return on invested capital. We are one of the few companies that alluded that strong return on invested capital consistently over the past 7 years and that continues this year.
The Haile optimization study we did talk about this in depth when we had our investor day about a month ago, and it did demonstrate the strong economics of the project and the long-term economics of the project in particular. The reserves increased by 70% up to 3.5 million ounces and if you include the economic inferred resources within the mine plan, you get 4 million ounce mining inventory, giving it a mine life with an average annual production of around 190,000 ounces per annum, significantly higher, well 60,000 ounces higher in fact, higher than the previous 43 101 report.
Of course, we've done at a lower gold price of $9.50 but nonetheless, the demonstration of the two economics of this project now that thye're revealed and very strong cash flows emanating from the project based on a $13,000 gold price before tax cash flows of $1.8 billion. Moving on to the topic of Haile and commission.
Obviously, we put a lot of effort and time into rectifying the commissioning issues that we've highlighted that started occurring in -- early in the second quarter. The mills have now been reconfigured with different grades and the distribution of load between the South mill and the Bore Mill is now being corrected so we've got increased load in the Bore Mill and we're getting higher throughput rates and importantly, we're getting stable consistent throughputs in the last couple of weeks.
Also complete is the -- putting the fine grind circuit into closed circuit. This is an important step to increase the load on the fine grinding mills to make them essentially work hard, and as a result, have been successful in reducing the grind side down to the targeted range of 15 microns to 20 microns.
So that's a very good news for us and we certainly keep monitoring that over the next weeks and months. The CO piping system, this is the wanders when they're transferring the slurry from one tank to the other in CI old circuit.
We did have a short-circuiting problem, quite a significant one, in the second quarter as we've ramped up the throughput, we've being getting slurries and short circuiting straight to the tailings. That's now largely been corrected, we're having installed two launders, new launders, which eliminate that short-circuiting risk on two of the tanks.
We will install another three over the coming weeks when we do our next shutdown and we do expect that to be finished in the end of the-- by the end of August. The tape line that delaminated a couple of months after we started up have all been stripped and so there is -- there's no interference with the day-to-day operation of the slurry old circuit because of these liners.
We have -- we plan to recommence the lining of those tanks in the near future. I will make a point that these liners therefore the long-term protection of the tanks and if you didn't have the liners in the tanks then you could easily expect them tanks to last 5 or 6 years without much risk at all.
So this is something that we intended to -- that we decided to do with the -- during construction. We still want to get it done and out of the way.
We don't expect they'll have a material impact on recovery as the take one tank off at a time throughout the rest of this year. And the control systems, we have done some improvements to the control systems to reduce response times and improve the operability of the process but we've made some significant progress there and that work will continue over the next months, throughout this year and into next year as well but that is improving as well.
On the subject of commercial production, we are ticking all the boxes. We just want to demonstrate the ability in the circuit and then be confident with the all going forecast for production in the plant.
Now moving on to page 7 and just some statistics there, lower results causing quarter two, you can see by the graph, the ramp up profile on Page 7 where the things started to go adrift in months five and six, and then in month seven we are on track to and that being July to bring that back up again. The all mind, comfortably feeding all to the mill.
We do have two pits operable and therefore, two sources of water so we can mix and match the feed to the mill. Waste mining, which is in line with plan the mill feed 409,000 tonnes of course is the annualized debt, it's 1.6 million tonnes slightly below the 80% target but that's what we're looking for improved throughput in the plant beyond that.
High grade is expected year-to-date around 2.25 grams per tonne and slightly lower head grade in the second quarter. And recoveries is where we have underperformed in the second quarter as a result of the issues that I have talked about already, and we do expect those to rebound significantly in the third quarter and beyond.
So I'll stop there and I'm obviously happy to take questions about Haile and other things at the end. I'll now hand over to Michael Holmes, our COO, to give you his presentation on safety and operating issues.
Michael Holmes
Thank you, Mick. Good morning, and good afternoon, everybody.
If we have a look at slide 8, I'll talk to you about the safety and health. We are continuing an increasing our focus and engagement on health and safety in the organization by implementing a leadership safety behavioral program in our workforce safety program that has been developed this year.
The leadership safety program is named the Gold Standard program and this focuses on visible felt leadership. As our leaders complete tasks such as attendance to pre-star meetings and completion of activities like stop and think task observations and has identifications in the field.
There is also a new component to ensure that the job has had an analysis and the job safety analysis are completed to the required standards. The Gold Standard has been rolled out to the superintendant leadership level and above.
And that includes ex mentors and the board, and the board recently completed their Gold Standard activity during their visit -- site visit to Haile. The workforce safety behavioral program is based on the workforce and the opinion leaders within the workforce deciding to make the right decisions about safety in the workplace by the safety behaviors that they select and commit to.
This program has been implemented at YB's and Mcray's [ph] and will be rolled out in the DPO this quarter and in Haile towards the end of the year and into next year. We're also focused on the quality of our investigations and the learnings from these with the dissemination and implementation of the corrective preventative actions and learnings across the business.
As the graph in the bottom of the page shows, we made some great achievements in the total recordable entry frequency late in the cadence since 2011. With the trend unfortunately reversing in 2016, which is a great concern.
We are currently tracking a total recordable injury frequency rate of 3.74 for the half year, down from 3.99 for 2016, with some further improvements to go from the proactive approach being implemented. Turning to Slide 9.
As previously mentioned, we are extremely proud of the work we are completing with our communities and the stakeholders and our operations, and the company's environmental, social and government's performance. We remain strongly committed in this area and it remains an integral pillar of our company.
In this slide, we've detailed only a few relatively small portion of the work that is being completed at all of our sites. However, highlighting a few of the comments, is the ongoing rehabilitation at all our sites and in New Zealand, we are currently at greater than 740 hectares of rehabilitation.
We are proud to talk about our programs for the protection and restoration of significant cultural sites like the Gaytans [ph] College in McCrays which demonstrates the historical living conditions of the Chinese immigrants that came to the area for mining. We continue to have a strong community support which is re-enforced in our yearly community surveys as well as the recent support in the consenting of the new Coronation North open pit which commenced mining in April in McCrays.
In the DPO, we still benefit from strong local and regional support and it just opened and handed over the new eastern Nueva Vizcaya Sky High School, which was built in the DPO and can support up to approximately 600 students. This compliments the president's kindergarten to Grade 12, K to 12 program, as the DPO now has the facility to teach you 11 to 12 students.
Previously, the children who wanted education past G10 had to leave town to get further education. We've also commenced construction of the family health center and a warden system within the community as well.
On June 22, we had the official opening of the Haile Gold Mine which is an exciting event attended by employees, our community and local, regional and state government officials. And at Haile, like all our sites, we continue to be focused on local employment and procurement.
Moving to the next slide, Slide 10. Looking at the DPO as an overview, the DPO's production was in line with expectations in the regionally updated guidance, with the gold produced for the quarter 42,900 ounces, and for the first half, at 105,647 ounces.
And copper production at 4,322 tonnes and for the first half, at 10,277 tonnes. DPO's production decreased quarter-on-quarter, was as expected and previously forecast, and on the back of a lower head grade and mill feed.
At the end of May, we completed the mining from the open point, and after that point, we supplement the I'll feed with medium and low-grade material stock -- from the stock piles. The all sustaining costs for the second quarter was at $147 per ounce for the first half as $15 per ounce, again in line with expectations.
But the first half of the year will be stronger than the second half as we continue in the second half to process ore from the open pit stock piles, which the stockpiles are round avout $24 million tonnes of ore being stockpiled. And this will be at the lower grades of the ore stockpile, so we are guiding the trend for the second half between 45,000 and 55,000 ounces of gold produced.
Moving on to Slide 11, had to DPO the transition to underground continues to advance well, with the mining of the decline and the installation of the infrastructure. We have commissioned two surface extraction fans for the underground, with one currently in operation due to the ventilation requirements and the other to be put in use as we deepen the mine.
The top pump station located on the services bench inside the pit, which is going to be used for the life of mine underground dewatering system was also commissioned. We will continue to install the underground pump stations as we progress further down the mine.
The ventilation rises, being installed in stages as we progress the vertical depth of the mine also. The decline, which is the black line in the diagram, is currently down to the 22 AVRL, which is at the full level, which is the turquoise color between the green shaded blocks in the presentation on the DPO underground sectional view.
The pace plan is progressing well as shown in the photograph and that's for commissioning at the end of the year when the first ore is expected from underground. Recent further studies on the geotechnical considerations in the mine planning in [indiscernible] have progressed, with the new mine plan being developed by the end of the year.
Turning to the next slide, Slide 12, at Waihi, we saw a steady quarter-on-quarter production with high mill feed offset by the lower head grade from the mine. Additionally, the [indiscernible] availability was higher in this quarter compared to the first quarter and the ounces produced for quarter two were similar to the ounces produced performance in quarter one at 25,560 ounces and 51,418 for the first half.
The all-in sustaining cost was high in the second quarter due to the [indiscernible] mine in the slightly higher New Zealand exchange rate. Looking ahead to the rest of year, we expect to operate with improved equipment availability and having just recently transferred a redundant lighter from the DPO to Waihi, and we also expect to mine from the high grade zones of the Correnso underground veins as well, Correnso mines.
So as such, we expect production to be slightly higher in the second half versus the first half and the improved all-in sustaining cost in line with guidance. Moving to Slide 13 from McCrays.
As mentioned, we commenced the mining in Coronation North in the quarter following the excellent communities all through the consenting process. The production for the second quarter was slightly higher than the first quarter at 39,788 ounces and 78,328 ounces in the first half, with an all-in sustaining cost of 1,140 for the second quarter and 1,154 for the first half.
Production Macraes is expected to increase in the second half with the fourth quarter being the strongest quarter of production. The drivers for this increase is the inclusion of the high grade, higher grade ore from the Coronation North pit, where we are currently focused on the pre-stripping of the over burden.
We expect to mine all sorts in the back end of the third quarter and we'll be ramping that up in the in the ore extraction format pit as the year progresses. I'd like to now hand over to Scott McQueen, the CFO, to go through the financial section.
Thank you.
Scott McQueen
Thank you, Michael. Good Morning and good afternoon to everybody.
The next few slides will give a bit more detail on the financial results which were highlighted by Mick in the opening and it certainly reflect the operational performance that Michael just outlined. Staying at the top line revenue, we had a first half revenue of just under $334 million, the Q2 revenue of $172 million, about a $10 million increase on Q1.
The increase reflects about a 3% higher sales volume largely drawn out of inventory as Mick mentioned and a higher average dollar price of around 3% across the quarter at $1262 an ounce. In addition, we saw an increase in copper revenue based on the higher volumes and the drawdown of concentrate 5800 tonnes of copper sales, albeit at a weaker price despite pound strength we've seen in recent weeks.
The EBITDA line we saw $186.4 million on the half as highlighted at the outset that's an extremely strong EBITDA margin of 56% delivering [ph] margin. The quarter that translated to $85 million, which is a bit of a step down on quarter one, that's a quarter-on-quarter movement really reflects a couple of key factors and the second quarter included a higher proportion of New Zealand ounces in the sale, which obviously a higher cost, plus as Michael mentioned, the completion of open pit mining in the first half of the second quarter was an end to our capitalization -- high capitalization of costs at Didipio.
We also a 30% quarter-on-quarter reduction in production while plane obviously increased the effective unit cost of production. We also, in the second half -- second quarter relative to quarter one, had an increase in G&A cost, mainly related to business taxes and employment taxes in the Philippines.
The timing of some corporate IT projects and settlement in Q2 of all the group incentive program. Q1 also was boosted slightly by $5.6 million one-time gain on sale of maximum securities.
The net profit line obviously $61.4 million as stated at the half. The same drivers nearly quarter-on-quarter had an influence at the EBITDA line in the net profit line.
We felt higher SG&A cost which is really just a reflection of the higher costs goods sold but the D&A portion being released there as we start to draw down inventories particularly in the Philippines. Turning to Slide 15 with more information on cash flow.
As you'd expect with the EBITDA margins we've seen, a very strong operating cash flow with $114.1 million approximately on the quarter. The increase quarter-on- quarter obviously reflects the higher revenue that more significantly quarter-on-quarter positive working capital movements, again reflecting the drawdown in inventories recently concentrated to DPOs but also the commencement of drawdown of ore stocks.
And highlight at this point that as Michael said, we've got 24 million tonnes of ore stocks. We will be commencing -- well we have started commencing the drawdown of the DPOs, that's $213 million that we spent previously, that we will now see while that will be related to the profit and loss account in cash flow, definitely a trend we've seen going forward with that money spent and we'll get the positive cash flow benefits of that moving forward will be a feature of the Didipio.
We also had a lower income tax payments in Q2 New Zealand, with Q1 settlement of last year's tax results and we have a current where we won't be paying any installment this year, so that's a timing benefit, we'll see that reverse early next year. On the investing cash flow front, we spent $137.6 million.
Quarter-on-quarter, it looks like we've actually step it up in quarter one included a benefit of $6.6 million on the same sales equitable marketable securities. I mentioned before, that is actually quite life like process $72 million in the quarter.
I guess the difference between the two is where we spend the money, quarter two a little bit less at Haile after capitalization in revenue certainly and the increase as we continue down the ground development, we will talk a little bit more about that in the next slide, talk the capital in a but more detail. The financing cash flow, pretty flat across the half.
Quarter one, we drew down an opportunity of about $12 million whereas in quarter two, we had no further drawn-out facilities. And $6.6 million negative there really reflects the pattern of the dividend no net change announced debt was drawn debt.
Turning to Slide 16, CapEx. This is a bit of busy slide.
And starting on the top left, essentially we've got the graph there shows you the total H1 standby location if you like. Obviously, weighted towards the development situation at Haile and the underground at the Didipio, the dark blue, although the Didipio did include some material costs related -- planned material costs related to risk works there, not 100% underground.
Moving across to the middle one, that's the same number obviously and it really breaks it down by nature, with $95 million being long withstanding principally again Haile and Didipio underground. $35 million is sustaining and $13 million of nonsustaining.
Below that, we take that $35 million of sustaining capital in the bottom left and break that down a bit further, a bit more flatter on that. Biggest area of that stand is related to Macreas, the bulk of that at least 1/3 of that being pre-stripped rather capital projects on site.
Didipio was a bit less, obviously, $4 million and that was road -- primarily road infrastructure and Waihi $9 million was underground development capitalized mining costs principally. Moving to the right there, we break down the exploration, the $13 million exploration, just to give you an idea of where it was mainly spent.
Certainly Haile and Waihi were the major focus as you would expect with the exploration activities there but there was obviously some exploration around Haile and the projects we have under review at Macraes. Not too much happening in Philippines as previously flagged.
Just there on the right there, we've got a breakdown of quarter two, just needs a little bit more detail on that. As you can see, it's $72 million, it's about half of our spend so quarter-to-quarter was pretty flat.
Unsurprisingly, the highest numbers there again relate to Didipio and Haile, with Didipio being the major consumer that quarter. Turning to Slide 17, shows our net liquidity position your last quarter now $127 million, very healthy $82 million in cash of liquidity to $72 million of marketable securities that we have at our disposal.
We have $45 million of undrawn facilities, that means $285 million actually drawn, the same as we did last quarter. As I said previously, no further drawdowns across the quarter at Haile sitting at $330 million including $45 million for the eye equipment in the field.
Our net debt position is $248 million which is very comfortable net debt asset ratio of 30%. A very strong position being at the half but commissioning issues of help and with that I will hand back to Mick to wrap up.
Michael Wilkes
Thanks, Scott. Let's move on to Slide 18.
And the point to emphasize here as a company, our vision and our strategy is very much long-term focused and the decisions that we've made over the years have been based on investing in long life, low-cost assets and nothing has changed there. The EBITDA margins and the return on invested capital that we have achieved over the last five years have been demonstrated through the performance of the share price.
So clearly, our strategy and our objectives have been nearly benefit. So we are a company that has a long-term focus and we are very much a company that's focused on returns to its shareholders and return on invested capital.
So the year ahead, our focus is clearly on continuing to create value and delivering on our commitments. Our production in the second quarter of the year will be stronger than the first half on the back of higher production in New Zealand and Haile, and Didipio as we've said many times, we expect it to decrease in the second half.
The development we will complete commissioning in the Haile process over the next few months and the expansion of Haile and the permitting of the extension of Haile, we expect to commence by year end. Similarly, we will complete the development of the first phase of the underground mine at Didipio in time for first ore from the underground at the end of this year, which will see production levels start to rise again.
Our exploration is continuing pretty well. We have strong results and progress at our Waihi mine.
We have good driven results coming out of Haile, and we continue to see opportunities for further exploration in other regions. And one of those is the commencement of joint venture in Argentina.
And so with that, I'd like to hand back to Jeffrey to wrap it up.
Jeffrey Sansom
Thank you. At this time, we'll open the lines to take questions.
For those of you who are seeking to ask questions, we'll be taking one question only. We'll now pause for a few moments while we wait for calls to queue and I'll turn the call back over to the operator to assist with this soliciting process.
Operator
[Operator Instructions]. Your first question comes from Michael Gray from Macquarie.
Michael Gray
Couple of questions on Haile and one on Macraes. At Haile, regarding the reduction at head grade, can you give us some color on what the main driver of this was and was it related to differing grade itself recoveries improved?
Craig Feebrey
Yes, it's a combination of both, Michael. It's where we are in the pit and also what not wanting to throw good grade out to tails.
So we are being -- we're not pushing the head grade just to produce gold, we are focused on stability in the plant.
Michael Gray
Okay. And are you happy with the block model grade reconciliation at this point or is that still a work in progress?
Michael Wilkes
Well, we've only just started mining, and as you've all known, we need to get a large enough portion of ore mine through the mill before we can start to make some definite comments about reconciliation but we have the [indiscernible] within the model at this point in time.
Michael Gray
Okay. And just shifting to the mill performance, subsequent to starting up in Q2, really improved both for throughput recoveries based on the MD&A.
Can you provide a little bit more color on the recent performance and expectations for Q3?
Michael Wilkes
I'd rather not make any promises on that, Michael, other than to say we have seen improved recovery and stability in the process which will lead to increases in throughputs.
Brian Quast
Okay, fair enough. How about a breakdown in terms of outside transition and so far achieved in the second half of the year?
Michael Wilkes
Well, we don't -- we're not showing any offside at the moment and we don't plan to treat that in a material way throughout the rest of the year. We really focused on itself on all course.
Michael Gray
Okay, thanks for that. And final question, just on Macraes.
Are you able to get a little bit more color on the grade profile in the second half of the year, will we see high grade coming in from Coronation North?
Michael Wilkes
Well I think even that calculated itself, we have -- we're looking to produce around 90 to 110,000 ounces of gold in the second half of the year. And so the mill's third quarter is still the same at about 5.8 million or 2.9 million tonnes for the half year and so recoveries would be 82%.
So I couldn't tell you exactly what that grade works out to be. But we have stated previously, in previous presentations, that the Coronation North at some point is that higher grade than what would be mining so far.
So it's at kind of 1.4 grade range which we'll start to see in the fourth quarter.
Operator
Your next question comes from Michael Slifirski from Crédit Suisse.
Michael Slifirski
Obviously, I think part of my question was just answered there in your suggestions Macraes recovery in the second half would be about 82%. So I guess the question underlying, that was the 80% in the half versus the 83% I think previously and the comment about [indiscernible] solving the issue.
Does that relate to a specific pit or depth? Was it a surprise, is it sort of pervasive than you thought or is Coronation clear?
Just trying to understand whether it's a metallurgical challenge that you'll overcome or just a spot in a pit. Any color around that would be useful, please.
Michael Wilkes
Michael, I've just Michael Holmes to comment on that level of detail.
Michael Holmes
Yes, thanks, Mick. Yes, so far it was -- I think we took an opportunity to treat some oxide material through the quarter.
And then had a -- it was a high grade material that was triggered but it had an impact on the overall recovery. We're blending it in and we'll -- at reduced rates, of course.
And it's -- it was just really an opportunistic while we had a bit of mill capacity to treat some high-grade offside material. So we're not seeing that and we don't believe we'll that in the Coronation or much of the primary pit material.
Michael Slifirski
Okay, thank you. Secondly, with respect to Didipio and throughput, I think in the past you've talked about a license, I think it was 3.5 million tonnes, you've done a fair portion of that in the first half.
You talked about maintenance lighters. So are you still above that 3.5 million tonnes constraint for this year or has there been some movement on the license that might delay to do a little bit better?
Michael Wilkes
So the license, the 3.5 million license is still in place. We're going through the process now of reviewing that.
We've done all of the work to allow all the required pre-work to have that license amended, now with the new Secretary, we're just basically waiting for the right time to reapproach the new secretary with regards to the request. So I think we're forecasting that it's going to be 3.5 continuing for this year but if there's an opportunity and the right window opens, we will certainly put that in front.
Michael Slifirski
Okay, thank you. And then finally, with respect to the comments on Haile about wanting to demonstrate stability before declaring commercial production.
Is there anything in the work program ahead of you that has to be completed that would enable you to demonstrate stability. So when we look at what you've achieved, it sounds like a lot of what you hope to achieve in terms of mill grades overcoming the short-circuiting someone has been largely completed.
So how do we assess when you're going to get close to commercial production?
Michael Wilkes
Michael, I think it's a sense of stability and continued consistent performance in the mill. We did want to demonstrate a said throughput in the mill that can be consistently achieved and we didn't want to see recoveries at OMEA expected rates.
So if we can deliver that performance over the next couple of months -- couple of weeks, I should say, then we'll be in a position to make that decision.
Michael Slifirski
That's great, thank you very much. And just one little semantic thing around wording.
In the quarter, we wonder how you talk about mill feed for the quarter being 409 2000 tonnes lower than expected, so that's not mill throughput rather than mill feed. There's plenty of feed available for the throughput.
Michael Wilkes
Yes, sorry. 490,000 tonnes for the quarter, not tonnes per annum.
Operator
Your next question comes from Geordie Mark from Haywood Securities.
Geordie Mark
Just a few questions from the two Michaels. On Haile, can you remind me what grain size you're down to in 18 or 15 microns?
Michael Wilkes
Probably in the range of 15 to 20 microns facility in that range.
Geordie Mark
Excellent, and that slide 7, you have the forecast ramp up for the throughput on a monthly basis. On that next forecast for the second half of the year, you don't want to sort of pin any forecasts on gold recoveries, do you, in relationship to that throughput increase?
Michael Wilkes
Well, recoveries we expect this year to be around 80%, and we expect that sort of numbers to be picking up.
Geordie Mark
Okay, thank you. And maybe just moving over to Didipio quickly.
Can you remind me of the lag time between provisional pricing through proper concentrated sales and pricing and then the final adjustments and how we can expect that to move on given what we've seen in terms of commodity price moving recently versus when those concentrated sales may have been put to see.
Michael Wilkes
Yes. With the subject to current prices effectively, Geordie, we do have a contract which stipulates that the buyer, which is Trapagora [ph], has the option to choose either a three months or a one months pricing.
And I think this year it's the same. It's a one month this year.
So there's not much exposure there, and we're basically exposed to current prices.
Geordie Mark
Thanks for that. And in terms of Didipio -- and terms of how should we deal with rehandling costs just this half of coming through?
Michael Wilkes
You mean the cost to rehandle the stock piles?
Geordie Mark
Yes, what are we looking at there?
Michael Wilkes
Michael, can you answer that question? If not, we can get back to you with that detail, Geordie.
It's a [indiscernible] fee but I couldn’t take one of these.
Geordie Mark
Right, okay. And just one last one, sorry.
You say that sort of a range was grade for stockpile this half of the year. Any sort of forecast for the range for copper grades as well?
Michael Wilkes
Similar to what they are at the moment and guidance for the full year is 18,000 to 19,000 tonnes of copper. Obviously impacted by lower throughput at the end of the year.
But we do see a fairly consistent copper grade through it all even with gold prices. So I can't remember what the exact head grade of the copper mill, is it's around that 4% to 5% mark.
Michael Holmes
A bit higher but yes.
Operator
Your next question comes from Chris Thompson from Raymond James.

Just one of my questions has just been answered but just a quick question on Waihi. You mentioned that back half of the year, it's going to be high in production.
Is that going to be entirely driven on grade or can we expect the mill throughput to step up a little?
Michael Wilkes
No, it's generally driven by the grade so the way the mining method of the old body is basically you have to go the extremities in the lowest points in mining. So you're actually mining lower grade portions at those extremities.
And so we'll see as we're mining in the second half here, coming into sort of the high grade portion of the Correnso mine. But again, I suppose the throughput should be improved a bit with improved equipment availability, and hence, the reason we got the redundant lighter down Didipio to ensure that, that'll be the case.
Operator
[Operator Instructions]. Your next question comes from Jeff Killeen from CIBC.
Jeff Killeen
I wanted to remind a bit to Haile again, just thinking about the performance you've seen over the course of this month, Mick. Without any specifics, would you be able to say that week on week, you've seen a consistent track higher in terms of grade, in terms of recoveries?
Michael Wilkes
We are talking many ways there, there, Jeff. We just finished the reconfiguration of the mills and about to just put the first two orders [ph] in the sales mix.
So yes -- and we've only just finished the circuiting of the grade circuit. So yes, the signs are positive but I will stop there and say that we've seen a trend.
Jeff Killeen
Okay, very well. And then, thinking again, coming back to commercial production, you mentioned what you're really looking for.
I think you outlined six criteria in the MD&A that you had to meet in order to get to that point. Would you be able to tell us one of those six that has been reached?
Michael Wilkes
So as you said, we reported in the second quarter our recoveries are well below what we expected and I wanted to head back up the stability in the plants should allow us to achieve that. Costs are in line with expectation, other than cost per ton and mining costs and processing costs, et cetera.
And grade in line with expectations, what we need to see is consistent stable performance, and therefore, consistent recoveries.
Jeff Killeen
Okay, very well. And has that passover from the commissioning team to the operation team happened yet?
Michael Wilkes
Well the operations group do have control of the plant. There are commissioning people still involved assisting in that process.
Construction people are still making the modifications necessary.
Jeff Killeen
Okay, fair. Switching to Didipio.
You commented that there was a slight drop in throughput in the quarter. Some of that was due to harder ores, is that an impact coming from starting the process stockpile?
Michael Wilkes
Yes, some of the stockpile, the lower rate stockpile, is from the harder portions of the pit. So that will just be consistent as we go through in some of the sections and as we start the underground, we'll be getting the [indiscernible] type material, but generally yes, the grade profile with the lower-grade material isn't some of the harder material that we have.
Jeff Killeen
Okay and thinking about depreciation being quite a bit higher in Q2 now that the pit is wound up. Would we start to see that decline going through the back half of the year or do you think it still could be elevated relative to say Q4 or Q1 of this year?
Michael Wilkes
Scott, can you answer that please.
Scott McQueen
Yes, I'd expect it to be relatively stable for the year as we draw the offering stockpile.
Jeff Killeen
Okay, great. And then lastly for me, just around Waihi.
You noted that you had a number of public consultations. Can you give us any insight on how those went?
Were there any specific items that are being brought forward by the local community?
Michael Wilkes
Well we're not in a position to talk about those discussions yet but other than to say that everything's tracking to plan, Jeff, and we are confident that we'll be able to start the permitting process for the markup project at the end of this year.
Jeff Killeen
Okay, apologies, one more for me. Then just switching to the Philippines again.
I noticed that you're still going forward with the legal process in regards to the previous suspension order around Didipio. How do you see that situation unfolding or is it still a little opaque at this point?
Do you think that you need to go through the final strokes of that legal process or is that something yet to be determined?
Michael Wilkes
Well, we definitely have to continue that legal process because we still obviously want that suspension order that was issued under the authority of the secretary at the time. So that process has to continue.
But it's important to understand the politics of it is that the president -- the new secretary and the cabinet will make sure that there is no political sort of blowback on the president as a result of any decisions they make from here on. So we are very confident in our case.
We know we have the support of the government in terms of following the proper due process and I think it is just a case of being patient and let the government go through their processes.
