Fabre
Key Facts
Overview
Fabre is currently BMR's only landholding in the province of Quebec, situated along the eastern shores of Lake Temiskaming about 32km southeast of the Cobalt Mining camp.
Extensive historic exploration work, including surface sampling and diamond drilling took place at Fabre following the discovery of high-grade Silver veins near Cobalt Ontario. Early exploration focused on Silver as well as base metals with rock sampling yielding significant Zinc and Lead values. Sporadic drill testing of the Fabre West target began in the 1940s.
Cobalt-Silver drill intercepts from this early drilling include:
- Drillhole 1947-40: 1.60% Cobalt & 59.90g/t Silver over 1.30m downhole from 207m and 2.50% Cobalt & 8.71g/t Silver over 0.91 m from 219m;
- Drillhole FV95-1: 2.70% Cobalt & 714.20g/t Silver over 1.07m downhole from 114m and 303.27g/t Silver over 5.56m downhole from 131m including 8.00% Cobalt over 0.49m from 131.41m;
- Drillhole TRS-F002-10: 68.36g/t Silver over 30m downhole from 66m.
BMR's exploration at Fabre commenced in 2016 with airborne magnetic and radiometric surveys followed in 2018 by prospecting, geological mapping, sampling and grid-based geophysical surveys (ground magnetic and a high-resolution 3D induced polarization "IP" ) surveys. Historic surface and drill core samples confirmed the area contained anomalous amounts of Cobalt, Silver and Zinc and geological mapping by BMR showed that the host rocks are somewhat like those at the McAra Cobalt deposit.
Inversion modelling of the 3D induced polarization (IP) data was correlated with the underlying geology and historic exploration results to develop drill targets. Drillhole targeting was based on bedrock geology, historic drill Cobalt-Silver results, proximity to the historic surface workings as well as two structural trends identified in the magnetics; north-south and northeast-southwest. A coincident high-amplitude chargeability anomaly was also targeted.
In early 2019, diamond drilling by BMR (18 holes for a total of 2917m) targeted the Cobalt-Silver mineralized zones yielding the following significant intercepts:
- 37.63g/t Silver over 8.00m from 37.0m; hole FAW19-001;
- 136.77g/t Silver over 21.13m from 90.87m, hole FAW19-001;
- 5.87 g/t Silver over 49.75m from 84.25m, hole FAW19-002;
- 419.33g/t Silver over 3.00m from 64.44m, hole FAW19-003;
- 123.83g/t Silver over 7.45m from 77.57m including 0.5m of 0.74% Cobalt and 1,740.00g/t Silver at 79.3m, hole FAW19-004;
- 34.09g/t Silver over 2.40m from 4.0m, hole FAW19-007;
- 37.59g/t Silver over 18.50m from 3.50m hole FAW19-010;
- 17.69g/t Silver over 3.25m from 87.00m, hole FAW19-010;
- 191.21g/t Silver over 4.00m from 4.00m, hole FAW19-011;
(All intercepts quoted as downhole core lengths)
The drilled area covers a strike length of 600m, and over that distance bedrock types vary widely. The Fabre West target appears to be a silver dominant vein system. Anomalous Cobalt assays strongly correlates with Copper and Silver correlates moderately with Cobalt, Bismuth, Zinc and Copper. These mineral associations are indicative of a VMS host rock environment.
Anomalous base metal values (Zinc-Copper-Lead) associated with the Silver zones were also reported including:
- 0.50% Zinc over 23.80m from 4.2m, and 0.18% Zinc over 49.75m from 84.2m, hole FAW19-002;
- 0.17% Copper, 0.15% Lead and 0.09% Cobalt over 7.5m from 77.57m, hole FAW19-004;
- 1.20% Zinc, 0.49% Lead and 8.65g/t Silver over 11.0m from 7.0m, hole FAW19-006;
Historical Background
Exploration at Fabre commenced in 1906 when a prospector’s grab samples returned high-grade Silver and Cobalt values (8% Cobalt and 6,500g/t Silver).
In 1947, diamond drilling intersected two intervals of significant mineralization in drillhole 40 yielding grades of 1.58% Cobalt, 59.92g/t Silver, 1.40% Copper, 3.09g/t Gold and 1.08% Pb over 1.4m and a second 0.9m interval grading 2.54% Cobalt and 8.7g/t Gold.
In 1995, follow-up drilling at Fabre West intersected high-grade mineralization in drillhole FV-95-1 yielding assays of 714.20g/t Silver, over 0.57m from 114.73m and 8.00% Cobalt and 600.00g/t Silver over 0.49m from 131.41m. Mineralization consisted of up to 15% sulphides, composed of Pyrite, Sphalerite, Chalcopyrite, locally Smaltite, and Cobaltite, that occur in veinlets, lenses, and disseminations.
In 2010, Tres-Or Resources collected a rock sample from a workings muck pile near the main prospecting shaft that assayed 0.99% Cobalt, 23.30g/t Silver and 0.33g/t Gold. The company also drilled two holes targeting the historic mineralization reported from drillholes 40 and FV-95-1. The best drill intercept was 201.00g/t Silver over 9m from 85.00m in hole TRS-F002-10.
Geology & Mineralization
The Fabre property is underlain by Huronian metasediments of the Gowganda Formation which unconformably overlie Archean Granitoids and felsic to intermediate Tuffaceous Metavolcanic rocks of the Abitibi Subprovince. The Nipissing Diabase occurs along the contact between the Granitic and tuffaceous units and a large northeast trending intrusion.
The Fabre West project is a high-grade Five-Element vein style target.
Two mineralization styles have been reported historically on the property: disseminated base metal sulphides hosted in Archean basement Volcanics and polymetallic vein style mineralization.
At the Fabre West target high-grade Silver-Cobalt-Copper-Lead-Zinc-Gold mineralization is hosted within a northeast- southwest trending shear zone that dips steeply to the north.
Current Exploration
BMR commenced exploration in 2016 with an airborne magnetic and radiometric survey.
Follow-up field work included rock sampling, geological mapping and prospecting followed by grid-based geophysical surveys, ground magnetics and high-resolution three-dimensional distributed induced polarization (“3D IP”) surveys in 2018.
In 2019 BMR carried out an initial drill program targeting the Cobalt-Silver mineralization hosted in the Archean rocks. Significant downhole core intercepts include:
- 37.63g/t Silver over 8.00m from 37.00m (Drillhole FAW19-001)
- 136.77g/t Silver over 21.13m from 90.87m (Drillhole FAW19-001)
- 419.33g/t Silver over 3.00m from 64.44m (Drillhole FAW19-003)
- 12.52g/t Silver over 16.00m from 146.30m (Drillhole FAW19-003)
- 123.83g/t Silver over 7.45m from 76.57m including 0.5m at 0.74% Cobalt and 1,740.00g/t Silver from 79.30(Drillhole FAW19-004)
- 34.09g/t Silver over 2.40m from 4.00m (Drillhole FAW19-007)
- 46.03g/t Silver over 8.00m from 5.00m (Drillhole FAW19-010)
- 17.69g/t Silver over 3.25m from 87.00m (Drillhole FAW19-010)
- 191.21g/t Silver over 4.00m from 4.00m (Drillhole FAW19-011)
A detailed review of the Fabre West project resulted in the decision to extend the high-resolution 3D IP survey grid with a follow-up survey in December 2020 that identified a strong high-amplitude IP chargeability anomaly southwest of BMR’s 2019 drilling which coincides with the historic high-grade Silver-Cobalt intercepts.
A follow-up drill program (3-4 holes totaling, 2,000m) targeting the south western extension of the IP anomaly is planned for 2021.
