Madoro Metals Corp. announced that a first-pass prospecting and sampling program on its 213-claim, 12,325-ha First Green Lithium property has resulted in the discovery of a potential swarm of lithium-bearing pegmatite dykes. The Property is located approximately 75km southwest of Val-d'Or in the Abitibi-Témiscamingue region of Québec, within a rapidly emerging lithium belt where large mineral claim holdings have been assembled by Brunswick Exploration Inc., Narrow River Resources Pty.

Ltd., Sayona Québec Inc., Renforth Resources Inc., Vison Lithium Inc. and Winsome Resources Inc. A network of forest-harvesting operation roads provide good access to the Property and have helped expose many new outcrops. The inaugural 10-day exploration program was implemented to obtain a fundamental understanding of the geological environment underlying the Property. A dyke swarm was discovered on the last day of field work in an area of dense moss and tree cover, so only five grab samples were collected over a 1,500m by 250m area in the central part of the Property.

Further surface work is required to better expose bedrock in this area. Geochemical analyses of the five grab samples show elevated levels of lithium, as well as rubidium, cesium, beryllium and tantalum - all good pathfinder elements. Three of the samples have K/Rb (potassium/rubidium) ratios less than 160 and two of these have ratios less than 60, indicating that the dykes are highly fractionated and therefore favourable for lithium mineralisation.

It is rare for fractionated pegmatite dykes to have K/Rb ratios below 160, so these initial samples from the dyke swarm are very significant. The Property's proximity to the mining centres of Malartic and Val-d'Or allows for low-cost exploration work. Québec is a strong supporter of exploration, production, and processing of critical strategic minerals (CSM), including lithium, and developing value-added industries such as battery and electric vehicle manufacturing.

In 2021, a special program to support CSM exploration was set up. This is in addition to existing refundable tax credits up to 38.8% for junior mineral exploration companies, and 69.4% flow-through tax savings for investors in Quebec and 38.4% for investors from the rest of Canada.
