K92 reports plant feed grade of 40 g/t Au over consecutive days, including a peak of 82.98 g/t Au

It seems like K92 Mining Inc. (K92) (TSX.V: KNT) has turned the corner, in a big way. While wide intervals of high-grade drilling have provided a lot of optimism in recent months, today’s positive production news is indicative of what this all means for the company in terms of mining and milling.
The company’s Kora Deposit, recently put into production after the May 2017 discovery of a northern extension and extensive subsequent drilling at grade control spacing, has exceeded all expectations, and early production numbers have been spectacular. Today, the company announced that recent mining efforts have resulted in process plant feed grade in excess of 40 g/t Au over consecutive days, including a peak of 82.98 g/t Au over a 12 hour period.
John Lewins, K92 Chief Executive Officer and Director, states, “The results from our mining, development, and grade control drilling at Kora North over the last month have been outstanding, and continue to build our knowledge of the deposit and its potential. The grades currently being mined from the 1185 K1 South vein are the highest that have ever been achieved from the Kainantu Mine, and further reinforces the confidence in our strategy of focusing on the development of the Kora deposit”.
Mining operations are currently focused on mining from stopes 1185 K2 0N and 1185 K2 0S, as well as from the development on 1185 K1 North and South from the second cross cut. All material from the first cut on the stopes was extracted during the month, filling of 1185 K2 0N was completed and drilling and blasting of the second cut commenced. Filling of 1185K2 0S has also commenced.
The second Kora North K1 vein has been mined for a strike extent of over 100 metres, and has averaged approximately 20 g/t. The 1185 K1 North, in particular, has returned some extremely high-grades, including 0.3 m @ 2,171.8 g/t Au in one face, and 0.6 m @ 1,126 g/t Au in another face. The results from 10 faces described by the company in today’s news detail the highest uncut face value reported being 157.2 g/t Au and 0.96% Cu over 3.45 m width, and the lowest being 12.42 g/t Au and 3.3% Cu over 3.15 m width. This high-grade zone is still being mined, so it’s full extent along strike and vertically has yet to be determined.
The high-grade material mined from the 1185 K1 South was blended with lower grade material from 1185 K1 South and the 1185 K2 0S stope. However, despite this, the plant reported daily feed grades in excess of 40 g/t Au on a number of days, with a peak of 82.15 g/t Au reported over a 12 hour period.
Additional to mining, grade control drilling from the first drill cuddy, DDC1 is now complete, with drilling from the second drill cuddy, DDC2 located 125 metres to the south, ongoing. Drilling from a third cuddy, located 200 metres to the north of DDC1, has also commenced.
K92 President, Bryan Slusarchuk, notes, “The discovery of the Kora extension announced in May was a game changer for the company. Since that time, the team onsite has continued to drill wide intervals of high-grade in this area. There is obviously a lot to be excited about with the excellent production news today, but we are also getting increasingly excited about what the ongoing drilling is indicating as to size potential. Kora is wide, high-grade and open for expansion, and drilling continues to go exceptionally well.”
The latest results from DDC2 from hole KMDD0047, which include 3.85 m at 2.83 g/t Au, 6 g/t Ag and 1.01% Cu (4.46 g/t AuEq), plus 6.49 m at 23.66 g/t Au, 27 g/t Ag and 0.16% Cu (24.24 g/t AuEq), plus 2.10 m at 9.42 g/t Au, 24 g/t Ag and 3.47 % Cu (15.044.46 g/t AuEq), plus 4.10 m at 2.36 g/t Au, 48 g/t Ag and 1.09 % Cu (4.64 g/t AuEq), confirm the continuity of both the K1 and K2 veins to the south over a strike length of almost 300 metres. The results from this hole have also confirmed the continuity of a high grade third vein designated KL1 running between K1 and K2. The intersection of one of the Kora lodes in KMDD0050 is considered important, as it extends the known Kora Vein system north to beyond 59375N.
