Oz Minerals Ltd (ASX: OZL) has received promising results with copper and gold intercepts from three prospects at Carajás in Brazil.
The three prospect, Grota Rica, Tapuia and Valdomiro are within trucking distance of the Carajás East hub central processing facility.
“The results of recent drilling in the Carajás are promising and demonstrate the growth potential of the Carajás East hub where we aspire to leverage central processing infrastructure with multiple high-grade satellite mines,” OZ Minerals Managing Director and Chief Executive Andrew Cole said.
“This low capital intensity, high margin approach in a highly prospective province is fundamental to the growing success of our hub approach in Brazil.”
Grota Rica Prospect
Follow-up drill testing of the discovery hole, which intersected a downhole interval of 10.1 metres @ 6.25% Cu, 2.98 g/t Au from 180 metres (ORVGVD-001), has intersected the same mineralised zone over a strike length of over 700 metres.
Drilling is currently continuing at Grota Rica with initial visual results identifying mineralisation extensions at depth and along strike NW-SE (assay results pending).
Proposed future work of a high-level mining study is intended to commence in September 2022. Of note is the identification of parallel trends of mineralisation have been identified through geological field mapping and geochemical soil sampling.
Both trends are yet to be evaluated. Tapuia Prospect Drillhole results beneath workings at Tapuia returned a downhole interval of 20 metres @ 1.9% Cu, 0.40 g/t Au from 65 metres and 22 metres @ 2.27% Cu, 0.35 g/t Au from 134 metres (OPCTD-003).
Drilling along strike to the southwest also intersected significant intervals of mineralisation (over a strike length of approximately 300m) and is currently open at depth and to the southwest.
Drilling is planned for Q4 2022 to explore potential extensions to mineralisation along strike.
Valdomiro Prospect
A discovery hole drilled beneath historical workings which span over 100 metres of strike, intersected a downhole interval of 27 metres @ 5.10% Cu, 2.61 g/t Au from 52 metres, including 13.5 metres @ 9.52% Cu and 7.01 g/t Au from 54.5 metres, in the first drillhole on the prospect (ORVSVD-002).
Induced Polarisation (IP) geophysical surveys have been completed in August 2022 and interpretation of this data is underway. Further drill testing to follow-up this initial intercept is planned for Q4 2022.
Valdomiro shows encouraging potential as this prospect is currently untested along strike and open at depth. Additional to drilling of the above prospects, geophysical surveying over several targets in the Carajás region is underway and is due for completion by end of 2022. The surveys aim to define further targets for potential drill testing in 2023.
