Redstone Resources Limited announced that geochemical assays have confirmed the previously reported hhpXRF analysesand show that the reverse circulation (RC) drilling completed at the end of 2021 has successfully proved that thick highgrade lenses of copper mineralisation intersected in historical drilling at the Chatsworth Prospect (Chatsworth), Tollu, have significant volume vertically and extend to shallower depths. Chatsworth is part of the Tollu Copper Vein deposit on the Company's 100% owned West Musgrave Project (the Project) in Western Australia. The West Musgrave Project, which includes the Tollu Cu Vein deposit, is located 40 kilometres east of the worldclass Nebo Babel nickelcopperPGE sulphide deposit now owned by OZ Minerals and has the ideal geological and structural setting for large magmatic NiCu sulphide deposits.

At the end of 2021 four reverse circulation (RC) drill holes, TLC188, TLC189, TLC190 and TLC192, for a total of 756m were drilled at the Chatsworth Prospect, Tollu. The aim of the drilling was to test for continuity of mineralisation vertically through the hosting subvertical vein system, and in doing so, test if the thick high grade copper mineralisation previously intersected in early drilling held volume between and beyond the historical drill holes, particularly at shallower depths than previously intersected. Preliminary results of the drilling using hhpXRF analyses were announced in the ASX announcement of 23 November 2021.

Geochemical assays have successfully confirmed these preliminary results, with generally higher Cu grades than the hhpXRF analyses but with slightly varying thicknesses. Drill holes TLC188 and TLC189, targeted approximately 1,520m vertically above a high grade copper intersection in historical drill hole TLC033, drilled in 2010 and 2,530m vertically below another high grade intersection in historical drill hole TLC034, also drilled in 2010. The historical drill holes suggest the mineralisation extends vertically between them but the vertical distance between the intersections is some 35m, a considerable distance for vein hosted mineralisation.

The geochemical assays from TLC188 and TLC189 have confirmed that the thick high grade copper mineralisation continues vertically, being maintained in the deeper intersection with 10m at 2.51% Cu from 174m downhole, including 3m at 4.71% Cu from 175m downhole (in TLC188) and swelling in the shallower intersection with 26m at 1.46% copper from only 61m downhole, inclusive of 1m at 5.1% Cu from 67m downhole (in TLC189).
