(Sharecast News) - Tertiary Minerals announced optimistic findings from a recent geophysical survey at its Brunton Pass Copper-Gold Project in Nevada on Thursday.
The AIM-traded firm said the survey, encompassing induced polarisation (IP) and resistivity techniques over 7.2 line-kilometres across four lines, spanning a total target strike length of 700 metres, revealed a coherent electrical chargeability anomaly indicative of sulphide mineralisation.
That anomaly, potentially bearing copper or gold, was observed consistently across all IP survey lines.
Of particular significance was the spatial correlation noted between the chargeability anomaly and previously-identified geological features.
Those include copper-mercury-arsenic soil anomalies, an alteration zone in trench T11 displaying heightened levels of pathfinder elements arsenic and mercury, and a gold-bearing zone in trench T2 where gold values reached up to 2.7 grams per tonne.
Moreover, resistivity variations seen in the survey were found to align with surface geology, aiding in the delineation of subsurface geological structures.
Given the promising nature of the findings, the identified chargeability anomaly had been designated as a high-priority drill target for potential epithermal gold or porphyry copper mineralisation.
Tertiary Minerals said it intended to schedule drilling activities as budgets permitted, ensuring alignment with its broader exploration strategy, including activities in Zambia.
"The IP anomaly defined by this survey is large and present over the full 700 metre length tested by the survey," said executive chairman Patrick Cheetham.
"The results from our previous rock, soil and trench sampling all vector towards this anomaly which is now a compelling drill target for the discovery of an epithermal gold or porphyry deposit."
Cheetham said much attention had been focussed on the firm's copper exploration projects in Zambia, particularly on the Konkola West Project, where drilling was in progress with the potential to deliver "transformational" results for the company.
"However, we continue to advance our key projects in Nevada, so I am pleased to be reporting these new results."
At 1030 BST, shares in Tertiary Minerals were up 4.86% at 0.1p.
