- 37gpt gallium, 651gpt rubidium, 57gpt niobium, 15gpt cesium, 11gpt tantalum over 73 meters from 17 to 90 meters.
- 44gpt gallium, 801gpt rubidium, 66gpt niobium, 16gpt cesium, 36gpt tantalum over 43 meters from 16 to 59 meters.
These results underscore the potential for a significant polymetallic deposit in the region, with implications for North American mineral security and technological innovation.
Critical Metals: A Strategic Resource
The discovery of these critical metals in Quebec is particularly timely given the current geopolitical landscape. Critical metals are essential components in modern technologies, including renewable energy systems, defense applications, and advanced electronics. Both the United States and Canada have identified specific lists of critical minerals vital to their economic and national security.
“China’s export restrictions on critical minerals have heightened the importance of North American deposits for tech and defense industries.”
Recent geopolitical developments have heightened concerns over the supply chain security of these critical metals. China, which holds a dominant position in the production and processing of several critical minerals, has implemented export bans affecting the West. These actions underscore the strategic importance of diversifying supply chains and developing domestic sources for critical metals to mitigate geopolitical risks and ensure the stability of essential industries.
Exploration and Drilling Results
The exploration program at the Discovery project has been extensive, with drill programs in 2018 and 2022 totaling approximately 4,128 meters across 22 holes. Originally initiated for gold exploration, the recent geopolitical developments regarding critical metals prompted the company to revisit these results, leading to the identification of significant critical metal deposits.
The zones containing anomalous gallium, rubidium, cesium, tantalum, and niobium were mostly found in pegmatite dykes, with several intercepts also containing metasediments, granite, and granophyre rock types. Additionally, indicators of a potential VMS (Volcanogenic Massive Sulfide) system were identified, including anomalous lead-copper-zinc, warranting further investigation.
Assay Quality Assurance and Quality Control
The integrity of the exploration results is underpinned by rigorous assay quality assurance and quality control measures. Drill core samples were collected every 1 meter, with careful attention to lithology types. The samples underwent comprehensive analysis at reputable laboratories, including ALS Canada Ltd and Northern Mining Analytical Laboratory, using state-of-the-art techniques such as fire assay, ICP-AES, and ICP-OES/MS.
QAQC samples, including blanks, standards, and duplicates, were inserted every 30 samples to ensure the reliability of the results. The review of these QAQC samples indicates acceptable levels of error, further validating the significance of the discovery.
