Review of project data for exploration targeting
The Casault project is located approximately 110 km west of the town of Matagami between Wallbridge’s Martinière and Detour East gold properties. Wallbridge has an option to acquire up to a 65% interest in the 177 km2 project from Midland Exploration. Casault covers more than 20 km of the Sunday Lake Deformation Zone, which hosts the Detour Lake mine 40 km to the west in Ontario. The option consolidates Wallbridge’s district-scale land position to over 900 km2 along the Detour-Fenelon Gold Trend, uniting the Company’s holdings seamlessly to the Québec/Ontario border.
The 322-claim Casault project hosts the Vortex Zone, a syenite-associated disseminated gold mineralized system grading up to 1.38 g/t gold over 26.5 metres (drilling intersection) and traced over a distance of 1.5 km. Gold-bearing porphyry intrusions have been identified in the northeast corner of the property.
As per the Option Agreement (see Wallbridge News Release dated June 18, 2020), Wallbridge has an exploration work commitment of $750,000 to be incurred on or before June 30, 2021. Review of project data for exploration targeting is underway.
Between 2015 and 2020, Casault was under a Joint Venture Agreement between Midland Exploration and SOQUEM. Midland regained 100 % ownership of the property by way of an agreement on February 27, 2020.
To date, a total of 38,550 m of drilling was completed on the property, which equates to only 218 metres per square kilometre, highlighting how underexplored this area is.
Those exploration efforts led to the 2017 discovery of the Vortex Zone, along with other mineralized intersections elsewhere on the property, including 10.4 g/t Au over 1.45 min drill hole CAS-12-07.
Casault is located along the Detour-Fenelon Gold Trend and covers more than 20 km of the SLDZ, which hosts the Detour Lake mine 40 km to the west in Ontario.
The SLDZ separates the Manthet domain to the north (dominated by gabbros and basalts) and the Rivière Turgeon domain to the south (clastic sediments akin to Porcupine sediments). Intermediate volcanics are bounded by the deformation zone in between the two domains. The Turgeon pluton (a hornblende-biotite bearing diorite) was emplaced to the south with the northern contact defined by the SLDZ. Finally, a polygenetic conglomeritic basin, Lac Causalt, is present in the center of the property.
The Vortex Zone, discovered in 2017, is the most significant gold mineralized system known on the property and has been described in detail by Castonguay et al., 2020 and the following description is taken from this source:
The zone is located at the western tip of the Lac Casault conglomerate basin at the contact between tholeiitic and calc-alkaline volcanic and volcaniclastic units of the Manthet Group. The west-trending, high-strain auriferous zone is spatially associated with subalkaline to reddish albite-sericite-hematite-altered alkaline porphyritic dykes. Gold-bearing quartz veins are transposed, boudinaged, and folded, but some are locally oblique and cut the main foliation. Strain increases from north to south and several steeply north-dipping mineralized intervals were identified. Zone 475 consists of deformed quartz-carbonate-sulphide veins in sheared carbonate-chlorite-sericite-altered andesitic blocky tuff with 5 to 20 vol.% pyrite (locally semi-massive) and 3 to 5 vol.% magnetite. Zone 450 comprises deformed quartz-carbonate (ankerite)±tourmaline veins and disseminated pyrite (2–5 vol.%) associated with high-strain zones and hydrothermal breccia.
Highlight intersections from the Vortex Zone include 1.38 g/t Au over 26.2 m, including 7.87 g/t Au over 2.22 m in drill hole CAS-17-96 and 1.30 g/t Au over 23.5 m, including 3.56 g/t Au over 6.0 m in hole CAS-17-95.
