Visible Gold Mines Inc. provided an exploration update on its MegaLi project located approximately fifty (50) kilometres south-southwest of the 2779 MW LG4 hydropower facility and 16 km from all-weather road access, JamesBay. The property consists of 78 mining claims covering a total area of 3,996.67 hectares (40 square kilometers) and is accessible by helicopter operating from a camp located along the hydropower reservoir. In September, the exploration team identified multiple outcropping pegmatites and boulders over the three (3) blocks (B,C,F) during 18 days of exploration work in the field.

A significant discovery was made on Block "C" where multiple large pegmatite intrusions follow the north-east regional structural trend. Individual pegmatite ridges can be followed for about 1km along strike. Peripheric exploration and mapping of the geology, indicated that potential thickness of these intrusions can be in a 10 to 50 metres range.

The distribution of outcrops suggests a 500 metres wide swarm composed of stacked intrusions. Host rocks of the pegmatite observed are composed mainly of amphibolite although described as a tonalite on the MERN website. Pegmatites identified show variable concentrations of potassic feldspar, albitic plagioclase, quartz and muscovite as main components.

Locally, tourmaline (black and dark blue) and garnet appear as accessory phases. The crystallization texture can be locally very coarse grain when compared with average pegmatite with individual crystals reaching locally 20 cm. Preliminary observations indicate common evidence of different crystallization texture corresponding to different magmatic episodes.

During this first scouting phase, 111 samples were taken for assaying including 79 samples originating from Block C. Rock chips fragments are collected from bedrock surface in areas that enable works. The mineralogical composition of fragments is described. A portable XRF is used on a routine basis to detect the presence of an excess of Rubidium.

This element is used to identify the presence of LCT pegmatites (Lithium-Cesium, Tantalum), which is the deposit type for spodumene bearing pegmatite, as largely recognized, and documented in the James Bay area. Based on scientific literature, the correlation between rubidium and lithium is generally accepted for exploration geochemistry purpose. The Company thinks that by promoting this approach, the identification of favorable sectors for lithium mineralization can be identified using the Rubidium enrichment.

This strategic approach aims at compensating for the difficulty of sampling large and representative areas of pegmatites and the often-discreet characteristic of spodumene. During a prospecting program, the portable XRF is used to discriminate pegmatites whose emplacement process was more favorable to lithium enrichment and spodumene crystallization. The lithium pegmatites at Corvette commonly contain elevated levels of Rubidium (Rb) and Cesium (Cs) compared to less differentiated granites, confirming their strongly differentiated signature that is typically for LCT pegmatites.

Whole rock rubidium contents are commonly 1000 to 4000 ppm Rb.
