Round 8 EDGI Results
Mineral Resources Tasmania has released the first Round 8 EDGI co-funded drilling project report. This project was completed in October 2023, well before the final reporting date for Round 8, with the rest of Round 8 projects expected to be released in early November 2024.
Drill core from the top of the upper vein and breccia zone intersected in NSD005. Interval from 131.0 m to 133.6 m has a length weighted average of 2.6 m @ 0.04% Cu, 6.4% Pb, 8.8% Zn, 842 g/t Ag, 0.06 g/t Au and 1.9% Sn.
The report covers Tarcoola Iron Pty Ltd’s Hole NSD005, at their North Scamander (Sn, W, Cu, Ag, Pb, Zn and critical minerals) project.
Data includes the final report and all available geological, geochemical, and geophysical data, as well as drill core photos. MRT has collected hyperspectral data from this core, which can be requested from info@mrt.tas.gov.au. Drill core is available for viewing, by appointment, at the Mornington Core Library.
NSD005 (732.7m) was designed to test at depth, historically drilled shallow Sn-Cu-Zn-Ag bearing hydrothermal breccia, associated with an intense magnetic anomaly. The target at depth was based on new magnetic inversion modelling, placing the NSD005 target 150 m below the historic drilling.
NSD005 intersected two zones of mineralisation. The first was a previously unknown shallow vein and breccia zone which assayed 32 m @ 141 g/t Ag, 0.34% Sn, 3.8% Zn, 2.0% Pb from 130 m. The second, deeper, lower grade zone comprised pyrrhotite +/- chalcopyrite stockwork veining and is interpreted as a possible near miss of a potential tin or copper dominant system. Assays from this deeper zone were only geochemically anomalous, returning 204.5 m @ 0.05% Cu from 369 m.
Geological features and anomalous In and Ga are taken by the company to indicate similarities to the Bolivian Tin Belt deposits.
