Tempest Minerals (ASX:TEM) reports it has intersected ‘considerable’ alteration and minor sulphides from an ongoing diamond drilling (DD) operation at the Clover Target, as part of its Meleya Copper-Gold Project in Western Australia.
The results, generated by the first diamond hole (WARDH75), have returned a thick (68m) laterite zone of weathered intrusives from 637.1m downhole.
Results from this hole also returned extensive highly sheared intermediate intrusives to 75m under the regolith profile, as well as three dyke generations that boast zones of additional alteration, including silification, calcite veins and trace sulphide species.
The company notes that a sharp change to greenstones occurred at 422m downhole, which indicated ‘significant’ silica and epidote overprinting until 569m downhole as well as a continuation of dyke swarms until the end of hole.
The continuous dyke swarms displayed ‘significant’ skarn-like alteration from 588-593m.
A parallel 4000m reverse circulation (RC) drilling program has now commenced with a goal of testing the multi kilometre thickness and structures present within the possibly demagnatised zone.
Drilling will also aim at testing a demagnetised northeast trending fault within the Big Bell Monzonite.
RC drilling will comprise 22 collars to a nominal depth of 200m to ensure that a continuous transect of the geology is revealed and will also test for potential extensions within key structures hosted in the Orion alteration zone.
Assays from a previous downhole electromagnetic survey (DHEM) conducted at the Orion target confirmed strongly mineralised zones and multiple stratigraphic positions hosting mineralisation exist within the area, as announced by the company in early September.
As of 2:35pm AEST, the company’s share price has increased by 6.67%.
Tempest Minerals is an ASX-listed company with a diversified portfolio of projects across Western Australia that are considered highly prospective for precious, base and energy metals. The company’s Meleya project is part of its flagship Yalgoo Portfolio which extends over a footprint of more than 900km-square, with Meleya making up 413km-square of the total project size.
Meleya is located about 460km north of the state capital city of Perth and is known to host volcanogenic massive sulphides (VMS), orogenic shear or vein gold and intrusive related gold (IRG).
With drilling at the project ongoing, Tempest Minerals announces that the recently commenced RC drilling program is anticipated to transition into a regional aircore (AC) and RC program of up to 13,000m.
Drilling is designed to penetrate zones of cover and laterite weathering across the newly identified belt.
