Tambourah Metals adds advanced Tambina gold project to WA portfolio
Tambourah Metals (ASX: TMB) has added the advanced Tambina gold project to its portfolio of gold, lithium and critical minerals assets in Western Australia.
The project represents an amalgamation of two historic mining leases that were explored for stratabound palaeo-placer gold mineralisation.
The hosting geological sequence includes rocks of the lower Fortescue group, folded into a south-south-east trending basin measuring 7.5 kilometres in length and 1.5km in width.
Coarse mineralisation
Historical exploration at Tambina by West Wits Mining (ASX: WWI) included geological mapping, trenching, rock and soil sampling as well as reverse circulation (RC) drilling.
This work identified coarse gold mineralisation associated with extensive and continuous ferruginous conglomerate units within the sedimentary sequence, employing bulk sampling methods to address issues with assay grade reliability.
Grades of up to 62.2 grams per tonne were reported in rock chip samples and visible gold in panned concentrates was identified from irregularly spaced sampling.
Prospective target
West Wits outlined a prospective target over approximately 500m of strike on the east limb of the folded sequence.
This target is coincident with a gold-in-soil anomaly grading more than 200 parts per billion identified in 2012 by Talga Resources (ASX: TLG).
Tambourah is preparing an exploration program to systematically determine the potential grade and extent of the Tambina mineralisation.
The program will also include mapping and follow-up drilling along the northern contact of the Tambina Supersuite to advance the search for gold and critical minerals.
Maiden drilling
Tambourah launched a maiden drilling program in September at its namesake gold project in Marble Bar, not far from Tambina.
The program comprised 11 holes for a total of 1,010m, with eight targeting high-grade lode gold at the historic Tambourah King, Federal and Kushmattie prospects.
The remaining three focused on lode and granite intrusion-related gold at the World’s Fair prospect.
The program was designed to follow up significant intersections from Tambourah’s RC campaign at Tambourah King in 2022, which returned best assays of 2m at 18g/t gold from 55m including 1m at 20.2g/t from 55m and 5m at 6.1g/t gold from 69m including 1m at 28g/t from 70m.
Funding received of $180,000 via the WA government’s Exploration Incentive Scheme (EIS) will support the company’s exploration efforts.
