ASX-listed exploration and mining company Los Cerros (ASX:LCL) reports extensional trench channel sampling has recorded gold grades up to 4.68g/t Au at the Kusi gold-copper prospect, located within the Ono Project in Papua New Guinea.
Channel sampling of a trench along strike from the Leah’s Lode skarn discovery trench has reported mineralised skarn assaying 22m @ 4.68g/t Au which extends the mineralised skarn unit to over 100m to the northeast. This extension supports the concept of a shallow dipping mineralised zone on the eastern side of Kusi.
Results from previous drilling and surface channel sampling of the southern portion of the upper limestone skarn unit included KSTC45A with 71m @ 4.96g/t Au, 4.77g/t silver (Ag), and 0.37% copper (Cu); FPR TR 1 with 20m @ 3.84g/t Aul and KSDD007 with 35m @ 3.04g/t Au from 136m.
Los Cerros reports Leah’s Lode is a 2022 discovery of an additional eastern skarn unit which was defined by a single trench with strong copper and gold grades of 8m @ 11.5g/t Au, 2.5% Cu, and 24g/t Ag. The recent result extending the unit by over 100m along strike is an ‘important’ confirmation of this new discovery.
Drilling scheduled to begin in March 2023 will be required to ascertain the true widths of mineralisation as the skarn dips similarly to the steep topography. The company says the presence of thick vegetation also makes assessment of true width challenging. Los Cerros also notes Leah’s Lode mineralisation remains open in all directions.
Los Cerros reports field work at Kusi has moved to the western and northern target areas to establish the full extent of the mineralised upper limestone skarn unit. This work will continue ahead of drilling.
Los Cerros is an ASX-listed exploration and mining company with a portfolio of projects in Papua New Guinea, and Colombia. These assets include the Andes and Quinchia projects in Colombia, as well as the Ono Project in Papua New Guinea.
The Ono project covers 1,630km-square of contiguous exploration licences covering an intrusive complex which is considered prospective for copper-gold oxide skarn, epithermal, and porphyry mineralisation.
