SilverCrest makes first pour at Las Chispas mine in Mexico

According to its latest feasibility study (2021), the Las Chispas mine is expected to produce a total 46.6 million oz. of silver and 503,600 oz. of gold from a 1,250 t/d operation over an initial 8.5-year life. On an after-tax basis, it would generate a net present value (at 5% discount) of $486.3 million, with an initial rate of return of 52% and a payback period of one year.

As outlined in the FS, the processing plant would use low-grade historic stockpiles through ramp-up of operations, reducing the reliance on underground mine production at the start of the operation. Metallurgical recoveries are also expected to reach FS parameters in 2023.

“We are pleased with the initial trajectory of the plant commissioning. While it is still early days in the plant ramp-up, we are encouraged by some of the operating indicators,” COO Pierre Beaudoin added.

Underground mining rates have increased during the most recent quarter, with production from stoping and in-vein development. These operating data, according to Beaudoin, will be incorporated in an updated technical report that is expected to be released the first half of 2023.

Located approximately 180 km northeast of Hermosillo, the Las Chispas project currently has 3.4 million tonnes of proven and probable reserves grading 461 g/t silver and 4.81 g/t gold. Only 21 of 45 known veins on the property have been included in this reserve estimate.
