iTech Minerals Ltd (ASX:ITM) has increased the territory deemed prospective at its Reynolds Range project in the Northern Territory, with fieldwork revealing rock chip samples of up to 735 grams per tonne (g/t) of silver (Ag), 11.4g/t of gold (Au), 14% lead (Pb) and 2.5% antimony (Sb).

The fieldwork has concentrated on the Lander Rock Formation at the Sabre-Falchion-Lander 1 prospects, expanding the mineralisation of gold, silver and antimony there.

Samples included11.4g/t Au, 10.4g/t Ag, 4.3% Pb and 2.5% Sb in one cluster; 3.4g/t Au, 130.0g/t Ag, 2.0% Pb and 1.1% Sb in another; and 1.0 g/t Au, 2.1% Pb and 0.8% Sb in a third.

A fourth sample picked up gold grading at 9.4g/t.

Sabre, Falchion and Lander 1 have been shown to host mineralisation over a strike length of 2.6 kilometres, and their horizon is on the western extent of the Scimitar and Reward volcanogenic massive sulphide (VMS) prospective horizon.

ITM believes it could indicate a transition to an epithermal gold-silver-antimony mineralisation style.

Managing director Mike Schwarz said the Reynlds Range project appeared to feature the mineralisation of numerous commodities at surface.

“Our ongoing mapping and sampling programs have identified numerous occurrences of high-grade gold, silver and antimony mineralisation across a strike of 2.6km,” he said.

“This occurs within an even broader zone of soil anomalism which extends to over 6.3km.

“Now that the iTech team has established the critical controls on mineralisation within the district we are shifting our focus to geophysical surveying and drill target generation.

“This includes the high priority Scimitar Cu-Au Prospect which the company intends to drill, once all approvals have been received.”

ITM has been trading at 6.7 cents.
