Lithium Projects

Mosaic now holds a portfolio of nine projects focused on lithium and strategic minerals for a total of 58,647 hectares. All these projects are in a geological environment favorable to the discovery of such minerals.

Pluton SM Project

Located directly adjacent to Patriot Battery Metals (PMET.V) Corvette lithium project, the 110 claims constituting the Pluton SM project are located in an environment comprising granitic intrusives with the presence of biotite and muscovite, two minerals considered as markers in the search for lithium. A few surface samples taken in this environment by the MERN gave indications of lithium and thorium contents. The latter is a potential indicator for the presence of minerals such as cesium or rubidium which are themselves useful markers for the search for lithium.

An extensive exploration program is planned for summer 2023.

Lithium SM Project

The Lithium SM property, 20 kilometers long by approximately 10 kilometers high, is intersected in its center by a EW fault as well as by a few faults trending ENE.

In the southern part of the property, numerous lithium anomalies associated directly with pegmatites currently suggest a favorable horizon of more than 5 kilometers.

Mirabelli SM

Located about 15 km south of the municipality of Eastmain and comprising 290 mining claims (15,370 Hectares), Mirabelli SM is accessible by the main road crossing the northeast part of the property and is located west of the James Bay Lithium project of Allkem (Galaxy Lithium Canada).

Maqua SM Project

According to data from the Quebec Ministry of Energy and Natural Resources (MERN), the new Maqua SM project, consisting of 69 cells with a size of approximately 3,569 hectares and located in the granitic suite of Vieux Comptoir, can offer phases of spodumene pegmatites. There is very little geological data currently available on this project. This vast project is located west of the Mia L1 and Mia L2 lithium showings recently acquired by Queensland Gold Hills (See press release of November 28, 2022).

Dalmas SM Project

Located in the Adina lithium showing sector from Winsome Resources. Recent drilling by Winsome has highlighted over 160 meters of pegmatite collectively intercepted while drilling below the recently discovered Jamar outcrop at Adina. In addition, the most recent analyzes of the Jamar outcrop yielded exceptional grades of up to 4.89% Li2O.

Gervais SM Project

The Gervais SM project consists of four (4) mining blocks in a sector comprising several showings of cobalt, copper, zinc, and nickel as well as lithium. This project totals 28 cells for a dimension of approximately 1,535 hectares. This project is located west of the Sirmac and Moblan lithium showings.

Bordier SM Project

The Bordier project comprising 48 cells for an area of approximately 2,651 hectares is located further south, along the Ontario border. According to the MERN, several random rock samples revealed significant lithium values.

Sakami SM Project

Made up of 11 cells covering an area of 570 hectares, the Sakami SM property is in contact with a biotite paragneiss and a white pegmatitic granite and an alkali feldspar and biotite and muscovite, tourmaline, garnet, and beryl in the Lake Sakami area.


Depending on the exploration budgets available, these projects should all be the subject of exploration work including a geological, geochemical, and geophysical survey as well as detailed sampling during the spring and summer of 2023. All these projects are accessible year-round via main and forest roads.

Lithium is a key player in the global decarbonization effort, as it is a key component of lithium-ion batteries as well as the next generation lithium-iron-phosphate (LFP) batteries used to power electric vehicles (EV). This essential mineral is also widely used in other industrial applications, such as cell phones, laptops, glass, and ceramic production, among others.
