Tambourah Metals (ASX: TMB) has continued to advance the potential of its Western Australian gold projects with multiple exploration successes during the December quarter.
The company successfully expanded on historic results at the World’s Fair prospect with key intercepts during the reporting period.
The World’s Fair program was supported by a grant of $75,000 from the WA government under the Exploration Incentive Scheme.
Tambourah completed a program of 11 reverse circulation (RC) and diamond (DD) drill holes at World’s Fair, targeting extensions to the quartz lode-style vein system and the untested granite-greenstone contact.
Geological mapping identified sulphide and gold mineralisation associated with the contact of a granitoid intrusion over 500 metres long adjacent to the World’s Fair site.
The DD program tested results from multiple electromagnetic conductors, representing potential sulphide mineralisation coincident with this contact.
The World’s Fair results added to Tambourah’s 2023 RC drilling program that also intersected shallow, high-grade gold at the Tambourah King prospect.
Drilling at Tambourah King confirmed the development of significant high-grade gold mineralisation at a relatively shallow depth.
Tambourah is now planning follow-up drilling aimed at extending coverage along strike, with a focus on the interpreted down-dip and down-plunge extensions to high-grade mineralisation within 100m of the surface.
Elsewhere, a single diamond hole at the Federal prospect targeted depth extensions to the known mineralisation and provided structural information to assist exploration targeting.
The hole successfully intersected a gold-hosting structure with an intercept of 0.7m at 3.22 grams per tonne of gold from 107.55m, including 0.2m at 9.65g/t within a steeply east-dipping shear.
It was the first hole to intersect gold at depth at the sparsely drilled Federal line of workings.
Tambourah also had success at the Duke prospect 650m south-west of World’s Fair, where sampling produced high-grade gold results of up to 26.8g/t and 20.8g/t.
Historic Duke workings extend for 160m in a north-south direction, parallel to the dominant trend of mineralisation at Tambourah.
The company collected rock samples from dumps adjacent to the workings, reporting the highest grades from several samples where breccia is developed adjacent to the quartz vein system.
The sampling at Duke – which is yet to be tested by drilling – produced consistently elevated gold grades, ranging from 0.97g/t to 26.8g/t.
