Follow Up To Reconnaissance Drill Programme In Finland
FireFox Gold Corp. (TSXV:FFOX) has commenced a new, detailed, bottom-of-till (BOT) sampling campaign at its 100%-controlled Jeesiö Gold Project in the Central Lapland Greenstone Belt, Finland.
The BOT programme builds on recently completed reconnaissance drilling, with a focus on testing an important structural corridor that passes through the Utsamo Target. Utsamo is situated between Aurion Resources’ Risti and Launi gold occurrences, and previous field campaigns have returned numerous samples with anomalous gold, including up to 4.6 g/t gold in surface sampling.
CEO, Carl Löfberg, said the BOT programme, which is expected to continue into April 2021, will aim to test the five-kilometre-long Utsamo Corridor of complex faults and shears that are believed to occupy a flexure in the Sirkka Shear Zone (SSZ).
“Jeesiö is a fantastic project with multiple gold targets in different settings over a huge area,” Mr Löfberg said.
“Much of the area in the north of the project is covered with glacial sediments, but where outcrop and boulders occur, we have seen considerable gold.
“Rupert Resources recently documented that their persistent use of BOT sampling integrated with geophysics led to the new discoveries through glacial cover at Area 1.
“This detailed survey at Jeesiö will be our first systematic work under the glacial cover in this area, and we look forward to generating priority drill targets from these results.”
BOT sampling is a shallow, percussion drilling method that allows for sampling below thick overburden in areas of limited outcrop, such as exists at Utsamo. The previous BOT campaign was reconnaissance in nature, comprised of only two parallel sampling lines 2.5 kilometres apart.
That work led to shallow drill holes that penetrated a thick section of fault gouge on a likely splay of the SSZ but no significant gold. Firefox will use this BOT campaign to build a more detailed structural map of the Utsamo Corridor with associated gold and alteration.
The programme will also test the northwest continuation of the so-called “Hinge Zone” approximately two kilometres southwest of the Utsamo Corridor.
Aurion has encountered high-grade gold in quartz veins associated with the Hinge Zone at Launi. Multiple parallel brittle-ductile faults have been identified passing through the Jeesiö Project, sometimes associated with high-grade gold in rock chips (up to 4.6 g/t). The BOT sampling programme will test these structures beneath the glacial cover.
The BOT programme design includes up to 700 closely spaced sample points in an area where bedrock is covered by an estimated 5 to 30 metres of glacial overburden.
The basal till and bedrock interface will be targeted using a percussion drill mounted on a tracked vehicle. Company geologists will submit the resulting samples for gold and ultratrace multi-element analyses.
The Jeesiö Gold Project covers approximately 142 sq. km of the prospective Central Lapland Greenstone Belt, proximal to other exciting recent gold discoveries in Finland.
The main Jeesiö targets include the Utsamo and Kataja Belt areas. Utsamo is situated directly between Aurion Resources’ Risti and Launi gold occurrences, while Kataja is only two kilometres southwest from the gold-bearing quartz-sulphide vein system at Launi.
