Osino Resources Corp. has provided an update on the infill drill program at the Twin Hills Gold Project. The objective of the program is to convert the first 2 years of mining from Indicated to Measured mineral resource category and to confirm and upgrade the Twin Hills Mineral Resource Estimate.
Osino remains focused on the financing and pre-construction activities at Twin Hills, including de-risking the mineral resource estimate and the initial years of production.
Heye Daun, Osino’s President and CEO commented: “We are highly encouraged by these excellent assay results which continue to come out of the Bulge infill drill program. The results confirm Twin Hills as a high-quality, low risk open pit gold project with significant upside potential. What stands out from the latest drill results are the significant length of these intercepts with highly consistent mineralization including some very pleasing, thick, high-grade intercepts of 1.5 g/t or more. Considering that these intercepts are unconstrained with no selective mining modelling applied yet, the upside potential of the Twin Hills mineral resource should be self-apparent. When we last completed such infill drilling at Twin Hill Central (THC) we were able to demonstrate a noteworthy grade increase, and we are hopeful that the same effect can be demonstrated for Bulge and the rest of the Twin Hills MRE as well, once our current round of infill drilling has been completed. Needless to say, a small change in overall grade will have an outsized effect on project economics.”
A total of 11,427m from 110 RC holes were completed within a block of 160m x 110m at Bulge pit (Figure 1). These holes were drilled on a 12.5m x 12.5m grid spacing and ranged in depth from 60m to 123m. Drilling was generally done to a datum with a maximum hole depth of 123m. The program conforms to the existing inclined drill pattern with holes drilled at minus 60° 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.
Most assay results from the Bulge pit have been received with only 13 holes outstanding from a total of 110. All remaining drill results are expected to be reported before end of November 2023.
An additional infill drill program was commenced during November at the Clouds and THC pits, with the aim of producing representative results for all of the main Twin Hills satellite pits (see Figure 1).
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 (Indicated & Measured) and 0.25moz at 1.10g/t (Inferred) (refer to press release dated June 12, 2023).
The program is on track to achieve its ultimate objective of confirming and upgrading the next MRE iteration.
