OSINO Resources Corp 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.
According to a statement issued by Osino’s president and chief executive Heye Daun on Monday, the objective of the programme is to convert the first two years of mining from Indicated to Measured mineral resource category and to confirm and upgrade the Twin Hills mineral resource estimate.
“We are highly encouraged by these excellent assay results which continue to come out of the Bulge infill drill programme. 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 mineralisation, including some very pleasing, thick, high-grade intercepts of 1,5 grams per tonne (g/t) or more,” he said.
Daun added that 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 Hills 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 mineral resource estimate 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,” he added.
Measured mineral resource means that part of a mineral resource, for which quantity, grade or quality, densities, shape and physical characteristics are so well established that they can be estimated with confidence, are sufficient to allow the appropriate application of technical and economic parameters, to support production planning and evaluation of the economic viability of the deposit.
The estimate is based on detailed and reliable exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough to confirm both geological and grade continuity.
A total of 11 427 metre (m) from 110 holes were completed within a block of 160m x 110m at Bulge pit.
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 additional infill programme at THC and Clouds pits is also aimed at converting the starter pit from the Indicated to Measured category, thereby substantially de-risking the first two years of ore mining.
The first tight infill drill programme was completed in early 2022 as an orientation study at the THC portion of the Twin Hills gold deposit.
The THC programme returned good results as expected and provided better definition of the ore envelope boundaries. – email: firstname.lastname@example.org
