Osino Resources announces assay results from infill drilling at Twin Hills

Osino Resources provided an update on the recently completed infill drill program at the Twin Hills Gold Project including the best hole drilled at the Project to date with an intercept of 61m at 3.21g/t. Osino remains focused on the financing and pre-construction activities at Twin Hills, as well as closely spaced infill drilling of the initial starter pits to validate modelling and de-risk initial production. Dave Underwood, Osino’s VP Exploration commented: “The systematic, tightly spaced infill drilling at Bulge is producing some very positive results with a best so far of 61m @ 3.21g/t, including 1m @ 106g/t. This result indicates that there are some small but very high-grade shoots within the Twin Hills deposit, that could enhance the resource numbers and production gold grade down the line. The drill program is being carried out at grade control spacing thus significantly de-risking the early production at the Bulge pit and further validates the modelling methodology used to derive the Twin Hills mineral resource numbers. A similar exercise at the Twin Hills Central portion of the pit was successfully completed in 2022 which validated the wider spaced modelling and resulted in a significant increase in grade over that mineral resource block without a loss in contained metal. We are very pleased to see that this effect seems to be playing out at the Bulge portion of the Twin Hills deposit as well. Once we have received all the outstanding results, we will quantify this data and incorporate it into an updated Twin Hills mine plan.” A total of 11,427m from 110 reverse circulation holes were completed within a block of 160m x 110m. These holes were drilled on a 12.5m x 12.5m grid spacing and ranged in depth from 60m to 120m. Drilling to a datum, the program conforms to the existing inclined drill pattern with holes drilled at minus 60 degrees dip towards the south-southeast. The drill program covers the Bulge year one starter pit hosting sub-cropping mineralisation, which plunges north-northeast to form the main ore shoot. The infill program results will drive an internal review of geological and resource modelling techniques and parameters utilised in the generation of the latest MRE comprising 2.94moz at 1.08 g/t and 0.25moz at 1.10g/t. Pending the remaining assay results, the program is on track to achieve its ultimate objective of confirming and upgrading the next MRE iteration. An additional infill drill program has commenced at the Clouds and Twin Hills Central pits with the aim of converting the first 2 years of mining from Indicated to Measured category, thereby substantially de-risking the first 2 years of ore mining, which represents the expected finance payback period plus a healthy margin.
