Sierra Madre Gold and Silver (TSXV: SM; OTCQX: SMDRF) expects to reach the 500 t/d commercial production rate at its fully permitted, past producing Guitarra mine complex in Mexico’s Silver Belt in Q4 2024.
Test mining and processing at the Guitarra complex is ongoing: flotation plant testing started June 25, 2024. The plant has processed 27,990 tonnes of mineralization as of Sept 20 (avg rate of 350 t/d over 30 days). Sierra Madre’s plan is to now move production up to 400 t/d before reaching the 500 t/d target before year-end.
Since the start of test mining and processing, Sierra Madre has delivered eight shipments – 466 dry metric tonnes – of silver-gold concentrate to offtake partner MRI Trading AG. With the start of concentrate deliveries, Sierra Madre expects weekly cashflows that should take the company through to commercial production without the need for further capital.
The brownfields site was previously operated by (and acquired from) First Majestic – the silver major is Sierra Madre’s single largest shareholder (44.5%). Institutions own 12.9%, Management & Founders hold 24.8%, Retail and High Net Worth own 17.8%.
Management has played key roles for managing exploration and development of more than 22Moz gold and 600Moz silver in combined reserves and resources. Sierra Madre’s technical team ran and operated the La Guitarra mine from 2003-2007.
