First Mining Completes Development Drilling and Expands Mineralization Potential at Springpole with SW Extension Zone
First Mining Gold Corp. announced results from its 2022 drilling program at the Springpole Gold Project in Northwestern Ontario. The campaign consisted of 62 drill holes totaling 5,834 meters, aimed at advancing geotechnical, hydrogeological, and geochemical studies. Significant findings include the identification of the SW Extension Zone, suggesting additional mineralization beyond the current resource area. Key intercepts from the drilling program include 1.08 g/t Au over 30.0 m in hole SG22-008 and 0.98 g/t Au over 33.0 m in hole SG22-021. The current resource is noted at 4.6 million ounces of measured and indicated gold. The company is optimistic about further resource growth following these encouraging results, as they proceed towards a Feasibility Study for the project.
- Identified additional mineralization in SW Extension Zone suggests increased resource potential.
- Significant drill intercepts, including 1.08 g/t Au over 30.0 m and 0.98 g/t Au over 33.0 m.
- Existing resource of 4.6 million ounces of gold presents a strong foundation for future growth.
- None.
The 2022 Springpole diamond drilling campaign comprised of 62 drill holes totalling 5,834 metres, and was focused on advancing geotechnical, hydrogeological, and geochemical studies related to metal leaching and acid rock drainage ("ARD"). Drilling in the southwest area of the Springpole Deposit has identified additional mineralization ("

Highlights of the 2022 drilling program include:
- Delineation of the
Springpole SW Extension Zone over approximately 150 m in the southwesterly direction and 550 m in the strike direction, with mineralization remaining open along strike and at depth for further testing - Drill hole SG22-008 intersected 1.08 g/t Au over 30.0 m from 300.0 – 330.0 m, targeting the western wall area of the
PFS Pit - Drill hole SG22-021 intersected 0.98 g/t Au over 33.0 m from 252.0 – 285.0 m, including 2.87 g/t Au over 7.0 m from 264 – 271 m, targeting the southwestern wall area of the
PFS Pit - Drill hole SG22-027 intersected 2.14 g/t Au over 10.7 m from 228 – 238.7 m, and 0.51 g/t Au over 30.0 m from 255.0 – 285.0 m, targeting the southwestern wall area of the PFS pit
"This is an exciting announcement by First Mining as we have been able to identify additional mineralization in the
A total of 62 drill holes for 5,834 metres were completed in 2022 supporting development advancement for the
Geotechnical drilling during 2022 consisted of 34 HQ-sized diamond drill holes totaling 3,756 metres supporting further characterization of the proposed open pit walls, the proposed construction dykes and additional areas of proposed mine infrastructure. Drilling within the area of the southwest PFS pit wall intersected an extension of the mineralization outside of the PFS ore zone and mineral resource area. Results of the program further supported drilling results from the 2021 site investigation programs and have established expansion opportunities for additional resource delineation.
A further 10 diamond drill holes totaling 1,612 metres were completed in order to collect sample material for the ongoing metal leaching/ARD studies on the Project. This drilling primarily targeted areas of waste and low grade within the PFS pit for ARD sample collection, and highlights from mineralized intersections include 1.17 g/t Au over 19.0 m from 85 – 104 m in drill hole SP22-ARD-010, 1.75 g/t Au over 16.0 m from 212.0 – 228.0 m in drill hole SP22-ARD-012, and 0.57 g/t Au over 44.0 m from 73.0 – 117.0 m in drill hole SP22-ARD-004. Selected core samples from the geotechnical drill program were also utilized for the ARD test work program.
The 2022 hydrogeology drilling formed part of ongoing hydrogeological site investigations required to support the Environmental Assessment ("EA") at Springpole. Drilling totaled 18 diamond drill holes over 406 m and included a program of shallow monitoring well installations which were positioned around proposed mine infrastructure and intended for long-term groundwater data collection.
During the 2021 development drilling campaign, two holes targeting the southwest wall of the PFS pit for geotechnical purposes intersected gold and silver mineralization outside of the PFS ore zone, highlighting a potential extension of the Springpole Deposit. As a result, the focus of drilling in this area shifted from geotechnical to near-resource exploration potential in order to delineate this new mineralization and build on the understanding of the geology in this area. Three additional holes drilled during the 2022 program for the geotechnical program (SG22-008, SG22-021 and SG22-027) also intersected mineralization in the SW extension area (see Figure 2).
Mineralization includes heavily disseminated pyrite with local concentrations of semi-massive sulphide within strongly altered and leached host rocks. The favourable lithologies present for gold and silver mineralization are trachytes, porphyries, volcanic breccias, and altered andesites.
The boundaries of this zone have yet to be fully defined, with opportunities for step-out drilling and additional exploration to extend the identified mineralization.
