has also identified multiple new load structures in the favorable diorite host in various locations along strike. The geometric relationships between structures and diorite employee individual loads may be limited by their potential strike length that remain open at depth. The airport drilling program has been very important in further delineating the favorable diorite host and associated golden- golden nomism along strike from the original West Island drilling. The res- the results have unlocked new areas with the necessary geological ingredients. The mineralization to occur up to five kilometers from West Island. One of the challenges with all of our drilling programs is long delays waiting to receive assay result, results in time to inform where to drill next. This is an industry wide issue and is holding back the ability to accelerate drilling programs in the ways we would like to. At Q we are still waiting on results from five diamond holes and over 70 air core holes, which restricts our ability to sensibly add additional drilling resources. At Red Lake two deep holes were completed as wide space step outs from the original intercept reported last quarter on the ore zone extension. One of the holes intersected high grade mineralization 200 meters away from the first, from the first hole, with the other hole drilling through the structure. However, it did not return significant mineralization. The results reported on page 12 are encouraging because they'll unlock large area of real estate that has not been previously drilled along the extension of the ore zone structure. Follow up drilling is currently stepping off the high grade intercept in hole 69 to expand the potential scale of minimization in this area. At Mungari, drilling underground at Kundana and East Kundana continuous concentration on small resource extensions and classification upgrades on future mining areas adjacent to existing development. Step out drilling into the foot wall of the K2 structure from the underground at Hornet has returned further promising intercepts of stacked load style mineralization at <inaudible>. Follow up drilling is underway to understand the significance to eliminated vein in hole 2130 reported on page 14 of this morning's report. The geology is similar to what would be expected on the main cases structure at <inaudible>, which is where the priority follow up drilling. At Ernest Henry, we have assessed H2 drilling priorities, which will be focused on developing all body knowledge for the PFS along with de-risking areas of the resource that require additional data support before production is scheduled. As Bob and Jake mentioned earlier, strong copper gold mineralization has been intersected at the 480 meter RL and remains open down plunge. With that I'll hand over the Lawrie. Thank you, Glen, and good morning, everyone. This morning I'll provide a brief update on the financial performance for the quarter as outlined on pages nine and 10 of the report. The group, we produced 148,000 ounces at an all in sustaining cost of 1347 per ounce. This aligns without guidance where we said the production would increase over the year and the all in sustaining costs would trend down from around 1450 per ounce in the first quarter. The IISC was approximately 5% lower than the September quarter. Our focus on portfolio quality is evident in that on a light for light basis, the divestment of Mount Carlton operation reduced our all in sustaining cost by $28 per ounce this quarter. As our production in cost profile changes in the second half, the cost benefit from this divestment will improve further. Group production and cost guidance remain unchanged at 670 to 725,000 ounces at an all in sustaining cost of 1135 to 1195 per ounce. With the performance of Red Lake in the first half, we to be at the bottom end of the production range and between in the top half of the cost guidance range. In terms of cashflow, we were fairly well in line with plan, excluding the underperformance at Red Lake. We generated 203 million of operating cash flow, which is up 4.6% and 13% excluding Mount Carlton. On a per ounce basis, our operating cash flow was up 10% quarter on quarter. This was against a flat goal price and lower copper revenue where the higher copper price was offset by planned lower copper volumes at Ernest Henry. Net mine cash flow was 53 million with our capital programs remaining on plan. We invested around 34 million in sustaining capital, where major project investment increased to 114 million as projects in Cowal and at Cowal and Red Lake progressed. Group capital guidance remains unchanged at 150 to 175 million for sustaining, and 440 to 505 million for major projects. We'll see an immediate benefit of the acquisition of 100% of Ernest Henry, where IISC will reduce materially in the second half of the year. More importantly though, our cashflow will be increasing. Based on our guidance and depending on the copper price achieved in the second half, we expect to realize an additional 80 to 130 million of net mine cashflow at Ernest Henry. This will be taken into consideration when determining our interim dividend. As previously announced during the quarter, we successfully priced the US 200 million US private placement for nine years at very attractive pricing to partially fund the Ernest Henry acquisition. This will be drawn down next month. We ended December with 1.15 billion of cash and net debt of 450 million. Now our <inaudible> is around 12.6% prior to the payment for Ernest Henry in early January. We are on track to be below the 29% projector at time of announcing the acquisition, and we expect to quickly be back within our targeted gearing levels and maintain a very wrong balance sheet. I look forward to updating you next month on the FY22 interim financial results. Thank you for your time this morning. And Darcy, please open the line for questions. Thank you. If you wish to ask a question, please press star one on your telephone and wait for your name to be announced. If you wish to cancel your request, please press star two. If you're on a speakerphone, please pick up the handset to ask your questions. Your first question comes from David Radcliffe from Global Mining Research. Please go ahead. Hi. Good, good morning, Jake team. So, uh, my question's on Red Lake. The, the commentary around mining rates does seem like, you know, more optimistic today, which is great, uh, especially with respect to, I guess, the mine efficiencies and dilution and, and opening up more mining freights up front. So just trying to think how we should think about, you know, the high development rates converting it to higher mine tons over sort of this year. And if you could maybe provide some sort of quantum how that comes through over the next c- couple of quarters. Uh, and then on grade, how we should sort of think about those numbers over the year. Obviously there's gonna be the sweetener from Campbell, but, you know, when do we from the, the operations today, how do we move closer to that reserve greater six,
