Torian Resources Ltd (ASX:TNR) has discovered a new gold mineralised zone from surface at the Mt Stirling Gold Project near Leonora in Western Australia.
The new zone is immediately east of the Viserion lode on 1840N and is towards the Wonambi Shear and Ursus Fault zone with results of up to 4 metres at 3.01 g/t gold from surface.
At Hanging Wall, high-grade down-dip extensions have been intersected on 1680N with results including 4 metres at 10.72 g/t from 240 metres including 1-metre at 20.48 g/t from 241 metres.
A further shallow Eastern mineralised gold zone has also been discovered in pre-collar of deepest drilling on 1760N with assays returning 1-metre at 1.20 g/t from 49 metres.
These additional high-grade gold intersections are the final results to be included in the upcoming Mt Stirling JORC resource estimate update expected later this month.
"Mineralisation in almost every hole"
Torian executive director Peretz Schapiro said: “Having intercepted gold mineralisation in almost every hole drilled at Mt Stirling, we are confident that our interim resource estimate upgrade will provide our company with strong fundamental backing as we continue to prove up the Mt Stirling Gold system, which remains open along strike and at depth.
“We are eagerly anticipating our long-awaited interim resource upgrade which is due later this month.”
The interpreted strike of the Mt Stirling gold system exceeds 1.16 kilometres and includes the Mt Stirling Main Zone, Hanging Wall, Viserion lodes and multiple eastern gold mineralised zones all remaining open along strike and down-dip.
Drilling at Stirling Well
Torian is progressing drilling at Stirling Well as part of its plan to expand its current inferred resource estimate of 253,500 tonnes at 2.01 g/t gold for 16,384 ounces.
Twenty holes are planned at Stirling Well for around 3,200 metres of RC drilling, targeting the depth of the gold system and also testing for multiple horizontal lodes.
Schapiro continued: “It is becoming clear that there is a high correlation with high levels of arsenic detected through our pXRF and gold mineralisation at Mt Stirling.
“As such, we are highly encouraged by the arsenic anomalies that have been detected around 500 metres NW and along strike of the current gold system, as well the anomalies detected around 200 metres SE and along strike of the same system.
“This bodes well for the continued extension of the gold system for our next interim resource update at Mt Stirling which we intend to complete later in the year.”
Next phase of exploration
So far, the company has drilled 12 holes at Stirling Well for 1,775 metres with drillers encountering encouraging quartz and sulphides zones within granite and below known extents of previous resource estimate area.
Torian is now compiling results from historical drilling campaigns as well as from its previous drilling campaign at Diorite to plan the next phase of exploration.
Schapiro added: “In addition to attempting to prove up a larger footprint at Mt Stirling itself, we will soon be actively following up with other high priority targets in the region.
“For instance, there have been historical gold intercepts 1.2 kilometres NW and along strike from Mt Stirling.
“We are excited about a potential connection between Stirling Well and Mt Stirling along the Nexus Fault, where we are utilising our pXRF and AV drill to test for arsenic anomalies in soils and in the oxides.”
Target generation
In addition to its active RC drilling campaign at Mt Stirling and Stirling Well, the company has been working through a target generation campaign utilising both air vacuum (AV) drilling and its recently purchased pXRF to test for arsenic anomalies.
To date, arsenic anomalies at Mt Stirling have correlated significantly with gold mineralisation.
Schapiro said: “We will also be following up on the Blue Jacket prospect to the east, which has historical gold intercepts alongside some deep historical shafts, in addition to following up on the newly discovered eastern zone at Mt Stirling and the prolific Ursus fault.
“We are also looking forward to follow-up work on Diorite in the coming weeks, particularly around the high-grade historical mines and soil and rock chip anomalies.”
