Lithium Pegmatites Identified at Medaro Mining’s CYR South Lithium Property

Medaro Mining reports the results of rock and soil samples procured during their 2022 exploration activities on the CYR South Lithium Property (CYR or the Property) situated in northern Quebec’s James Bay region.

The results show higher lithium values than was anticipated in several pegmatites sampled throughout the Property. These pegmatites zones also indicate concurrent lithium anomalies in soil samples and will be additionally analyzed through trenching and drilling activities. Anomalous values of other rare metals, like cesium, beryllium, tantalum, and niobium, were also discovered in the rock and soil samples.

Program Description

The 2022 summer work program included rock and soil sampling and geological mapping directed at ascertaining pegmatites for their potential to host lithium mineralization.

In total, 600 soil samples and 18 rock samples were gathered as part of the work program. A total of 42.58-line km of ground magnetic and VLF geophysical survey was also finished as per this work program. The results of rock and soil samples can be found in this article, and the ground geophysical survey will be published shortly.

Assay Highlights

Rock Samples

  • Rock sample assays indicate lithium values in the range of fewer than 15 parts per million (ppm) to 1,480 ppm, with five pegmatites tested for higher lithium, necessitating a follow-up work of trenching and drilling.
  • Rubidium (Rb) values are in the range of 3.2 ppm to 285 ppm, and cesium (Cs) values are in the range of 6 ppm to 1770 ppm.
  • Beryllium (Be) values are in the range of 6 ppm to more than 5,000 ppm (beyond the lab’s detection limit) with six samples showing more than 5,000 ppm. 

Soil Samples

  • Lithium values fall in the range of less than 15 ppm to 73 ppm. A group of anomalies in the middle of the Property is said to be a high-value target for trenching and investigative drilling.
  • Niobium values are from less than 2.4 ppm to 24.3 ppm and tantalum values are from 0.3 ppm to 21.2 ppm.
  • Rubidium values are in the range of 3.1 ppm to 127 ppm.
  • Cesium values are in the range of 0.3 ppm to 26.6 ppm.
  • A number of samples with higher cesium, rubidium, tantalum, and niobium values are concurrent with lithium anomalies.

All soil and rock samples were packed and tagged using best practices and were transported to Activation Laboratories (“ACTLABS”), Ancaster, Ontario, for sample preparation and examination using lab code Ultratrace 7.

The Company hopes to progress to the next stage of its exploration activities based on the new input gained from the rock and soil sample program at the Property.

The foundation for the commencement of this preliminary surface exploration work at CYR is to discover new pegmatites throughout the Property to help set up targets for a potential future diamond drill program.

CYR is one of four Quebec properties of Medaro, and all are close to each other, which offers cost savings when carrying out numerous drill programs by sharing core shacks, camps, and other equipment.

The Company will offer an update on the feasibility and timeline for a future drill program as soon as the finalized ground geophysical survey results have been fully examined and reported.

We are excited to see promising results on our exploration efforts for the CYR South property. James Bay area is a prolific region for discovering high grade lithium deposits with several new discoveries made recently. The Company is planning to carry out trenching and diamond drilling programs on the identified targets.
