THE DRILL SERGEANT: S2 Resources (ASX: S2R) has identified a new gold mineralised trend to the east of the company’s 100 per cent-owned Aarnivalkea gold prospect in northern Finland.
S2 Resources identified the new trend by carrying out base of till (BOT) drilling, which retrieves a single end of hole sample at the interface between the base of the glacial till and the subjacent bedrock, and is essentially a way of collecting rockchip samples from beneath the transported cover.
S2 had undertaken the BOT drilling in lieu of planned extensional diamond drilling at Aarnivalkea, which could not proceed due to unusually warm conditions in the arctic preventing the ground from freezing and restricting rig access in swampy areas.
The new BOT anomaly is largely located on a gentle rise which can be drilled year-round, and the company is planning diamond drilling to test it as soon as possible.
The recent BOT drilling tested beneath an ionic leach gold anomaly and has identified a 1.2 kilometre long north-south striking zone of strongly altered and deformed bedrock with associated strong gold, arsenic, antimony and copper anomalism.
The bedrock in this zone comprises strongly sheared and sericite, silica, carbonate, sulphide altered greenstones with quartz-arsenopyrite veining.
Drilling produced numerous samples grading greater than 0.5 grams per tonne gold with a peak value of 4.3g/t gold, and these have associated anomalous arsenic, antinomy and copper pathfinder elements.
This corridor is open along strike to the south.
“It is likely that the southern extension of this corridor has been terminated by a late fault and displaced 1.5 kilometres to the northeast, where another line of reconnaissance BOT drilling has intersected gossanous quartz assaying 10.7g/t gold together with a similar suite of pathfinder elements,” S2 Resources said in its ASX announcement.
“BOT drilling is ongoing with the aim of further defining the extent of this new trend and its potential fault-offset continuation, and a diamond rig has been sourced to commence drilling in mid-March.”
