K92 Mining Announces Strong Q1 Production Results at Kainantu Gold Mine - Record Throughput of 1219 tpd in March
K92 Mining Inc announces production results for the first quarter (“ Q1 ”) of 2022 at its Kainantu Gold Mine in Papua New Guinea, of 28,188 oz AuEq or 24,152 oz gold, 1,524,827 lbs copper and 28,142 oz silver. Sales during the first quarter were 29,728 oz AuEq or 26,471 oz gold, 1,247,967 lbs copper and 24,899 oz silver.
During the first quarter, Kainantu delivered its second consecutive quarter at Stage 2 Expansion run-rate throughput, processing 99,611 tonnes. Mine performance was also strong, exceeding mill throughput, with 100,124 tonnes of total mill feed mined.
Importantly, in March, the mill delivered a monthly average throughput record of 1,219 tpd, significantly exceeding the Stage 2 Expansion target of 1,100 tpd. Mill throughput exceeded 1,300 tpd for 45% of the days (14 days) during the month of March, continuing to demonstrate much higher throughput rates than the Stage 2 Expansion design.
The strong performance bodes well for the Stage 2A Expansion to expand plant designed throughput another 25%, to 500,000 tpa or 1,370 tpd, at an estimated growth capital cost of US$2.5 million. The expansion was approved in October 2021 ( see October 7, 2021 press release: K92 Mining Announces Stage 2A Expansion to Increase Throughput +25% to 500,000 Tonnes Per Annum at Kainantu Gold Mine) and works are currently underway with the new filter press installed and operational; the additional TC-1000 secondary crusher arrived on site in late Q1 and is planned to be installed in Q2, while the new flotation tanks are scheduled to arrive in the second half of 2022 when commissioning of the expanded plant will commence.
Mine productivity was impacted by delays being experienced in the delivery of underground mobile equipment as a result of the ongoing challenges in the global supply chain. A new twin boom jumbo, 45 tonne truck and 17 tonne loader were all due for delivery at the beginning of Q1, however, the jumbo arrived in late Q1, while the truck and loader only arrived in country in early April. The equipment all arrived already commissioned and is expected to provide an immediate boost to mine productivity and development.
During the quarter, long hole stoping continued to perform to the design, with operations focused on Kora’s K1 and K2 veins, and Judd’s J1 Vein for a total of 8 levels mined. Mining on Kora was conducted on the 1150, 1170, 1225, 1245, 1265 and 1285 levels, and Judd on the 1235 and 1285 levels. Development on Judd along the 1285 level will establish the next series of long-hole stoping panels that is planned to commence mining in Q2.
The operation delivered head grades of 8.3 g/t gold, 0.76% copper and 11.5 g/t silver (9.7 g/t AuEq) in Q1. Gold grades were below budget as development had not yet opened up higher grade stoping areas that were scheduled for March and will now be mined in Q2. Metallurgical recoveries averaged 90.9% for gold and 91.1% for copper during the quarter.
Twin incline development made significant progress, advancing 15% above budget during Q1. As of March 31, 2022, incline #2 (6m x 6m) advanced to 1,101 metres and #3 (5m x 5m) advanced to 1,063 metres. Over the last three quarters, twin incline development has advanced 10% above budget.
COVID-19 Operational Resiliency
The Kainantu Gold Mine operates under a comprehensive COVID-19 Management Plan and has continuously operated during the pandemic. A considerable focus is on health and safety and risk-mitigation. Under the COVID-19 Management Plan, K92 has: established a Government-recognized testing lab facility utilizing qualified medical personnel on site; established quarantine and isolation facilities for incoming staff; and implemented enhanced hygiene, disinfecting and training systems and procedures. Additional controls were implemented in 2021, requiring external COVID-19 testing prior to travel to quarantine at site in addition to on arrival at site before reporting to quarantine. A focus has been supporting Government efforts at a national, provincial and local level through the 1.5 million PGK (Papua New Guinea Kina) COVID-19 Assistance Fund and a further 1.0 million PGK of additional assistance funding to Eastern Highlands Province.
In addition to its various control measures, K92 continues to make considerable progress increasing resiliency through vaccinations of our expatriate and PNG national workforce, with vaccinations administering on site well underway. Over 75% of our workforce (employees and contractors) have received at least one vaccine dose. The Company is in close communications with the provincial and national health authorities of Papua New Guinea and the Government of Australia, in addition to the Papua New Guinea Chamber of Mines and Petroleum to deliver an effective pandemic response.
Note - Gold equivalent for Q1 2022 is based on the London Metal Exchange quarterly spot average price: gold $1,879 per ounce; silver $24 per ounce; and copper $4.53 per pound. Gold equivalent for 2021 is based on the following prices: gold $1,800 per ounce; silver $25 per ounce; and copper $4.35 per pound.
John Lewins, K92 Chief Executive Officer and Director, stated, “In the first quarter, we continued our positive operational momentum, delivering near-record mining and milling rates, the second consecutive quarter at Stage 2 Expansion run-rate and significant advancement of the twin incline, exceeding budget by 15%.
The strong performance of the process plant was a major positive development, with monthly record throughput of 1,219 tpd achieved in March, considerably greater than the 1,100 tpd Stage 2 Expansion run-rate target. In March, 45% of days exceeded 1,300 tpd and it is also important to highlight that this strong performance was achieved before the installation of key Stage 2A Expansion upgrades, such as the additional TC-1000 secondary crusher and flotation cells. The Stage 2A Expansion is targeting 1,370 tpd, with commissioning planned for the second half of 2022. The arrival of a new jumbo in late-Q1 and truck and loader in early April, is expected to provide a further boost to mine productivity and development. As noted in our operational guidance, AuEq production during the second half of the year is expected to be the strongest, and we are very pleased by the strong performance of the plant to date.
Notably, while Q1 was once again impacted by COVID-19, due to a large number of cases in Papua New Guinea from the Omicron Variant resulting in some operational disruptions including elevated absenteeism, I am pleased to report that our mitigation measures, including our quarantine system, were effective in reducing the impact. As Papua New Guinea emerges from the Omicron wave, restrictions at Kainantu are now at the lowest level since before the start of the pandemic. This is expected to have a deflationary impact on costs as pandemic-related overheads such as quarantining are significantly reduced in addition to increased operational efficiencies in general.
Exploration is also a major and increasing focus, with the vast majority of our drill rigs focused on resource growth. Drilling is underway at Kora, Kora South, Judd, and Judd South. We recently completed our drill program at the Blue Lake porphyry and look forward to providing an update. We see the potential to increase our exploration budget during the year.
Lastly, the achievements over the last two years, would not have been possible if it were not for the extraordinary dedication, commitment, and resourcefulness of our workforce. The Governments of Papua New Guinea and Australia have also been a major factor in our success.”

Twin incline development advancement exceeded budget for the second half of 2021 and was in line with budget during Q4.
- Subsequent to year end, K92 announced its updated Kora resource estimate and Maiden Judd resource estimate. The updated Kora resource estimate reported a Measured and Indicated Resource of 2.1 million ounces at 9.20 g/t AuEq and Inferred Resource of 2.5 million ounces at 9.48 g/t AuEq. The maiden resource estimate for the Judd deposit reported a Measured and Indicated Resource of 0.13 million ounces at 11.00 g/t AuEq and Inferred Resource of 0.18 million ounces at 5.66 g/t AuEq. The resource estimates will form the basis for the upcoming Definitive Feasibility Study and Updated Preliminary Economic Assessment (see February 23, 2022 press release).
- Subsequent to year-end, K92 announced high-grade and record thicknesses from maiden surface step-out drilling results at both Kora South and Judd South. The results include the discovery of a previously unknown vein, and the discovery of significant mineralized dilatant zones at both Kora South and Judd South. An airborne geophysics survey was also completed, defining extensive new targets (see February 16, 2022 press release). Exploration at Kora South and Judd South has increased to two drill rigs operating, with plans underway to add a third drill rig near term. In 2022, up to 11 drill rigs are planned to be operating.
John Lewins, K92 Chief Executive Officer and Director, stated, “ 2021 represented another major step forward for K92. Operationally, Kainantu delivered record throughput, production and finished the year particularly strong. Q4 also provided our most complete quarter to date, including record quarterly production, mine throughput, mill throughput, strong metallurgical recoveries, low all-in sustaining costs of $672/oz and, once again, a positive grade reconciliation to the resource model. This resulted in the Kainantu operation beating our updated guidance on both production and costs. Financially, K92 is the strongest position it has ever been, with a record cash balance of $71m and no debt, well positioning the Company to fund its growth and exploration.
In terms of production growth, we achieved the Stage 2 Expansion run-rate of 400,000 tpa (1,100 tpd) in late-Q3, and in early Q4, announced a Stage 2A Plant Expansion to increase throughput another 25%, as the mill has continued to show that it is very capable of operating at much higher throughput rates. Q4 recorded 21 days with throughput exceeding 1,300 tpd and a daily record of 1,538 tonnes. Commissioning is expected for Stage 2A in the second half of 2022, at a plant expansion capital cost of approximately $2.5m. Subsequent to year-end, we announced a high-grade updated Kora resource estimate and maiden Judd resource estimate, providing the basis for the Definitive Feasibility Study and Updated Preliminary Economic Assessment for the additional expansion, Stage 3. Work is well underway on these studies.
Exploration also delivered strong results during the year, reporting 177 drill holes at Kora and Judd. Drilling recorded some of our highest drill holes recorded to date, with many highlights including hole KMDD0415 recording 7.51 m at 192.50 g/t Au, 8 g/t Ag and 0.22% Cu (192.92 g/t AuEq, 4.11m true width) from the K1 Vein, 6.45 m at 105.96 g/t Au, 11 g/t Ag and 0.60% Cu (106.95 g/t AuEq, 4.06 m true width) from the K1 Vein, and at Judd, hole JDD0022 recording 8.51 m at 48.56 g/t Au, 47 g/t Ag and 0.54% Cu (49.93 g/t AuEq, 6.25 m true width) from the J1 Vein. Importantly, due to the proximity of our exploration to mine infrastructure, production is able to rapidly benefit from exploration success. At Judd, in just over a year from the discovery of high-grade underground, its first long hole stope was mined in Q4 and has become a new major mining front for K92 that is expected to provide a boost to operational flexibility in both the near and long-term.
The recent strong results from surface exploration drilling at Kora South and Judd South, also show very promising potential and plans are well underway to ramp-up exploration, with the second drill rig now operating and a third drill rig planned near-term. Concurrently, Kora South and Judd South surface sampling and mapping is underway, stepping out along strike towards the interpreted A1 Porphyry. Our property wide airborne geophysics results also show that exploration is potentially just scratching the surface in terms of both vein and porphyry exploration. We see an elevated likelihood that our exploration budget will increase for 2022.
Lastly, I would like to underscore that these significant accomplishments were achieved during the burdens from the COVID-19 pandemic. Our workforce has been extraordinary during the last two years and our resiliency towards COVID-19 continues to strengthen. The support of the Governments of both Papua New Guinea and Australia have also been a major factor in our success as well. ”

Petrographic Study confirms Feni Porphyry system
Photo: Figure 1: Feni Island – showing Kabang drilling area – other prospects also shown
Adyton Resources Corporation is pleased to report that petrology work carried out on the highly successful diamond drill hole ADK004 (see TSXV Release 01 December 2021) supports the existence of two styles of mineralization – a shallower epithermal style overprinting an earlier porphyry mineralization event (as reported by earlier workers), confirming that we are in a highly mineralized system.
Petrological work carried out by Mintex Petrological Solutions on 14 drill core samples (on 12 polished thin sections and two polished buttons for SEM) has confirmed the geological understanding that two styles of mineralization exist at the Kabang prospect.
The first nine shallower samples show epithermal characteristics with pervasive adularia alteration overprinted by kaolinite-dickite and alunite (advanced argillic) alteration with variable paragenetically late pyrite-chalcopyrite-arsenopyrite mineralisation in veins (azurite was observed in one sample).
The five deeper samples are plagioclase-phyric phenocryst-rich diorite porphyries with occasional apatite phenocrysts. These brecciated porphyries are chalcopyrite-rich with chalcopyrite replacement of clasts and matrix, as well as mineralised thin quartz veins indicative of porphyry style mineralisation.
Overall, the shallower samples from this deeper suite of rocks show adularia (potassic) alteration overprinted by advanced argillic alteration (hosting the shallower epithermal gold zone), and the deeper samples also have an advanced argillic overprint into the porphyry system (hosting the underlying porphyry copper / gold mineralisation).
Adyton Resources CEO, Mr Tim Crossley, said that “we are extremely excited by the results of the petrology work which has confirmed our views that Feni hosts a highly mineralized system. Commenting further he noted that the area around ADK004 is open in all directions for porphyry style targets, in particular the area to the north where there has been no drilling carried out”.
Mr Crossley went on to say “This petrography work follows on from the company’s significant gold and copper intersects reported in December 2021 including the world class copper intercept in hole 4 of 6.4m @5.1% copper and 1.6 g/t gold with 35m of disseminated 0.3% copper and 1.1g/t gold above the high-grade massive sulphide zone.
These intercepts followed on from the previously reported intercepts from holes 1 and 3 of 144.8m from surface of 0.8 g/t Au in hole 1 and 84 m @0.6g/t in hole 3.”
The Feni Project
The Feni project hosts an existing inferred 1.46 Moz NI 43-101 compliant gold Resource1 and lies within the Feni Island Group at the southeast end of the 250 km long Lihir alkalic volcanic island chain, which is largely Pliocene-Pleistocene in age. The chain lies 40 – 60 km off the east coast of New Ireland, PNG (Figure 1), with Feni, located in a highly mineralized part of PNG, having many geological similarities to the world renowned giant Lihir gold deposit. Further to the south-east lies the large (Panguna) Bougainville copper / gold porphyry deposit.
The focus of the initial drilling program at Kabang was to test both the shallow epithermal gold zones and deeper porphyry copper potential (Figure 2). The Company’s maiden drilling program of five diamond holes (1,982m) at Feni was completed in late 2021 (see TSXV Announcement: “01 December 2021: Adyton hits significant copper at Feni Island 6.4m @ 5.1% Cu (including 3.6m @ 6.9% Cu”).

Further drilling success at Woodlark Gold project
Photo credit: Geopacific Resources - Figure 1: Kulumadau cross section
Geopacific Resources Ltd is pleased to provide further updates on its successful grade control and resource extension drilling at the Woodlark Gold Project.
Chief Executive Officer, Tim Richards commented
“The grade control drilling campaign continues to deliver encouraging results. We have now received assays from 34 grade control holes with a substantial number reporting significant high-grade intercepts, supporting our view that there is considerable upside potential within the existing pit shells. The further seven resource extension drill holes returned favourable results that highlight the broader exploration potential across the mining leases. The continued trend of positive results across the drilling campaign highlights the potential that exists across Woodlark Island to expand our mineralresources. I look forward to updating the market in coming periods as we continue to receive further grade control and step out drilling results.”
Woodlark Grade Control and Exploration drilling
The Company continues to receive positive results from its ongoing grade control and exploration drilling campaign at the Project (ref ASX release 16 February 2022).
Further results from 23 holes in the grade control drill campaign at Kulumadau have been received, highlighting upside potential within the existing pit shells.
The results include a series of near surface high gram-metre intercepts (Figure 1) within the Kulumadau pit. A further 25 holes remain completed, with assay results pending.
Further results from seven drill holes in the resource extension drilling campaign at Busai were also received, with encouraging high grade intercepts. All are within 82 metres from surface (Figure 2).
The resource extension drilling results to date from Kulumadau and Busai reinforce the potential for pit extension, with all three planned pits at the Project open along strike and at depth. A further 5 resource extension holes from the Kulumadau deposit are awaiting assay.
Exploration drilling to the north and east of the current Kulumadau resource was commenced in February 2022 and is ongoing. There are currently 14 holes from this program awaiting assay.
A reconciliation of the grade control model to the Mineral Resource (ref ASX release 12 March 2018) will commence upon receipt of all outstanding samples.
The drilling campaign for the remainder of the first half of 2022 will focus on Woodlark’s significant near-pit exploration potential within the existing mineral lease (Figure 3).
