Octava Minerals (ASX:OCT) has observed two visible semi-massive sulphide intercepts at the Sweeney’s prospect within the greater Federation Project in western Tasmania.
The company has restarted drilling at the prospect, with three holes completed across 457m to date. Drilling is expected to extend for a total of 2,000m.
Hole OFD003 outlined visible semi-massive sulphides within a quartz-gangue to occur in two separate lodes.
Octava reports the outside of sulphide quartz lodes to display a halo of sericite, siderite alteration that hosts minor disseminated pyrrhotite, pyrite, and sphalerite.
The company conducted drilling at hole OFD003 to test the upper limit of the modelled electromagnetic plate that was returned in a fixed loop electromagnetic (FLEM) survey.
The FLEM survey targeted a shallow area of historical drilling. The core from Octava’s recent drilling at hole OFD003 has been cut, with samples dispatched to the laboratory for analysis.
Meanwhile, Octava has identified ‘high grade’ zinc, copper, silver, tin, and indium from a rock chip sampling campaign at the Anomaly 1 prospect, which is located 750m northeast of Sweeney’s.
Rock chip sampling returned 12.75% zinc, 0.81% copper, 199 grams per tonne silver, 0.61% tin, and greater than 500 parts per million of indium.
These results follow on from historical drill intercepts of 37m @ 0.21% copper, 0.26% tin, 0.86% zinc, and 33g/t silver from 40m at the Anomaly 1 prospect in 1982.
Octava says outcropping mineralisation identified at Anomaly 1 is located within a broader coherent multi element historical soil anomaly that is illustrated by contoured tin.
The company is focused on aiding the global demand for critical minerals for sustainability purposes across their assets in Western Australia and Tasmania, as reported by Mining.com.au. Currently, Octava is focused on exploration across its Federation and Byro projects.
Octava Minerals is a Western Australia-based explorer focused on targeting copper, base metals, and rare earths.
