Highlights
- Assay results from two holes confirm cobalt mineralization extends over a broader area, including:
- 47% Co and 0.50% Cu over 0.65m in FCC-18-0015
- 77% Co and 2.67% Ni over 0.30m in FCC-18-0020
- Cobalt is found as two different styles of mineralization in each hole: breccia-style dominated by pyrite in drill widths up to 25m, and vein-style within an interpreted fault structure
- Cobalt mineralization encountered over 250m north of the historic Frontier Mine workings in an area never previously drilled
- Follow up work continues including downhole geophysical surveys and televiewer imaging to determine a possible orientation of the breccia zone and faults. Additional drilling is planned later in the year
“We remain encouraged by the cobalt potential of the Woods Extension Zone. Broad breccia areas have not been seen previously at either the Frontier or Keeley Mines and new fault zones continue to be found. We have confirmed cobalt occurs in two different structures at relatively shallow depths that may extend to surface. The key objective of the 2018 exploration program is to identify potential targets in the Cobalt Camp that could be amenable to open pit mining.”
Assay results from the two most recent holes confirm that cobalt mineralization extends over a broader area than previously known within the Woods Extension Zone (Table 1). In FCC-18-0015, cobalt mineralization occurs within a breccia zone with pyrite, while in FCC-18-0020, cobalt veining is associated with an interpreted fault. Both intersections reflect a complex structural setting hosting cobalt as well as silver, nickel and copper which will require further work.
In early 2018, 1,436 metres of diamond drilling were completed across seven holes to explore cobalt mineralization found north of the Frontier Mine workings in the Woods Extension Zone. In 2017 several carbonate veins were intersected suggesting either a broad deformation zone had developed or that the Woods and Watson Veins are not linear as historical records indicated. The Woods and Watson Vein systems were historically the most prolific producers in Cobalt South, accounting for over 80% of the production in this area of the Cobalt Camp. Newly identified cobalt-rich veins have been associated with both the Woods and Watson Veins as well as a new vein found between these two structures. Surface mapping interpreted these structures to trend in a north-west orientation.
To follow up on these results, in 2018 an east-west fence of four holes was drilled more than 200m to the north of the 2017 holes (Figure 1). An additional three holes were also drilled near the 2017 drill holes to test for an interpreted east-west fault previously thought to terminate the Woods and Watson Veins. The new cobalt intersections reported here reflect the identification of mineralization over 250m north of the underground workings of the Frontier Mine. Copper and nickel associated with cobalt were previously intersected near Frontier Mine, suggesting a similar setting may exist in both areas.
Drill hole FCC-18-0015 is the western-most hole of the fence, intersecting a 25m zone of chlorite-epidote altered and brecciated mafic volcanic rocks. Pyrite occurs as veins and within the matrix, infilling the brecciated rocks. Cobalt mineralization occurs in two intervals within the zone where chloritic alteration and shearing have developed. Discrete cobalt minerals and calcite veins are not visible and assumed to be finely disseminated. Throughout the breccia zone disseminated chalcopyrite occurs with pyrite and in the altered wallrocks. The orientation of this mineralization is not confirmed but may represent an offset version of the Woods Vein or may be part of another north trending structure, the Beaver Lake Vein, known to contain silver-rich mineralization.
Drill hole FCC-18-0020 was drilled northward to test for the presence of an east-west fault historically considered to terminate the Woods and Watson Veins. Overall the volcanic rocks within the drill hole are altered, specifically at 110m downhole where a 10m interval of sheared and chloritized rocks is considered to coincide with the east-west fault. Within this interval cobalt minerals occur within a discrete calcite vein. Pyrite and arsenopyrite occur over a three metre wide halo adjacent to the vein. Nickel with cobalt mineralization have been previously reported in a hole approximately 50m south of this intersection (January 10, 2018).
Follow up work to this drill program has included downhole geophysical surveys and televiewer imaging of drill hole FCC-18-0015. Magnetic intensity, resistivity, natural gamma radiation and chargeability were measured to characterize the breccia zone and cobalt mineralization to determine if ground geophysical surveys can be effectively used. The televiewer images will be integrated with the existing geological log to determine a possible orientation of the breccia zone. Detailed mapping in outcrops is possible in the summer to determine if an expression of this zone can be found at surface.
Woods Extension Zone
The Woods Extension Zone was identified from assay results at the northern extent of the Frontier Mine. Early assay results from the Frontier Mine included an intersection of 0.83% Co and 30 g/t Ag over 0.48 metres (November 2, 2017), which was the first indication of a possible extension of the Woods Vein system.
Most cobalt-rich veins intersected demonstrate that mineralization extends outside of the silver-bearing veins. A new cobalt-nickel vein was found between the Woods and Watson Veins, grading 0.57% Co and 1.40% Ni over 0.40m (January 10, 2018), suggesting a network may exist where faults and folds converge. The highest grade cobalt veins occur at the north end of the Frontier Mine, specifically along the Watson Vein.
Quality Assurance and Quality Control
First Cobalt has implemented a quality control program to comply with common industry best practices for sampling and analysis. Samples are collected from drill core from a range of 30 to 100cm length. Half-core samples are submitted for analysis. Standards and blanks are inserted every 20 samples. Duplicates are made from quarter core splits every 20 samples. Geochemical data were received from SGS Canada in Lakefield, Ontario, Canada. No QA/QC issues have been noted. SGS has used a sodium-peroxide fusion and ICP finish for analyses on all samples. Where applicable, over-range (>1%) Co, Ni, Cu, Zn, and Pb are determined by a separate fusion and ICP finish. High silver values (>1,000 g/t) are determined by gravimetric separation and fire assay finish.

About First Cobalt
First Cobalt aims to create the largest pure-play cobalt exploration and development company in the world. The Company controls over 10,000 hectares of prospective land covering over 50 historic mines as well as mineral processing facilities in the Cobalt Camp in Ontario, Canada. The First Cobalt Refinery is the only permitted facility in North America capable of producing cobalt battery materials.
First Cobalt seeks to build shareholder value through new discovery, mineral processing and growth opportunities, with a focus on North America. On March 14, 2018, the Company proposed a friendly, all-share acquisition of US Cobalt Inc. for its Iron Creek Project in Idaho, U.S. The transaction remains subject to shareholder and regulatory approvals and other closing conditions. This transaction is intended to further enhance First Cobalt’s position as a leading pure-play North American cobalt company.
