Sierra Madre Gold and Silver Ltd. (SM:TSX.V; SMDRF:OTCQX) provided an update on the progress of its planned two-stage expansion at the La Guitarra silver gold mine complex. The company stated that the first stage of the expansion was designed to increase production rates from the current 500 tonnes per day to between 750 tonnes per day and 800 tonnes per day of processing capacity. Processing plant upgrades, tailings handling improvements, and equipment purchases related to the expansion were reported to be underway.
The company said that once the first stage was completed, the planned second phase would increase processing capacity to a range of 1,200 tonnes per day to 1,500 tonnes per day by the third quarter of 2027.
Greg Liller, chief operating officer and executive chairman, stated in a company news release, "Once completed, the first stage of the expansion is expected to not only deliver increased throughputs but also efficiencies across the operation, such as deposition of a portion of the tailings underground and higher equipment availability. The next major work milestones are the ball mill and thickener installation."
The current crushing circuit consisted of a primary jaw crusher, a two-tier vibrating screen plant, and a three-foot short head cone crusher. The company reported that installation of a new three-foot standard head crusher was expected to expand crushing capacity to between 750 tonnes per day and 800 tonnes per day. Construction began in December 2025, and initial testing of the circuit was underway.
Earthworks for the foundations of the thickener, designed for 750 tonnes per day to 800 tonnes per day, were described as nearly complete. Fabrication of the tank, mixing rake, electrical components, and support structures was reported as well advanced, with project completion on track for the end of the second quarter.
The company also reported that it had purchased a used 11 by 12.5 ball mill that was being refurbished. The mill had a nominal capacity of 600 tonnes per day at a minus three-eighths-inch feed size and was expected to expand processing capacity to the 750 tonnes per day to 800 tonnes per day objective when used with one of the existing mills. Projected completion was reported as on target for late in the second quarter.
To support the planned production increases, the company reported equipment purchases, including two new scoop trams, one used scoop, and the rebuilding of two existing scoops. It also purchased a second StopeMate long hole drill and completed the rebuilding of a second Jumbo drill. For haulage and materials movement, the company purchased four haulage trucks and a second front-end loader.
Expansion Work Streams and Equipment Installations at La Guitarra
The company reported that installation of a new three foot standard head crusher was expected to expand crushing capacity to between 750 tonnes per day and 800 tonnes per day. Construction began in December 2025, and initial testing of the crushing circuit was under way. The company also stated that options were being evaluated for constructing a second crushed ore storage bin to provide additional backup storage capacity and potentially allow crushed mineralization to be reduced to a nominal one quarter inch size depending on water content.
Earthworks for the foundations of the thickener designed for 750 tonnes per day to 800 tonnes per day were nearly complete. The thickener was described as enabling a portion of tailings to be deposited as paste fill in old stopes and allowing for the construction of a filter circuit to produce dry stackable tailings. Fabrication of the tank, mixing rake, electrical components, and support structures was reported as well advanced, with completion on track for the end of the second quarter.
The company stated that a used 11 by 12.5 ball mill had been purchased and was being refurbished. Installation would involve constructing a new foundation based on manufacturer blueprints, and the mill would be placed at the location of a previous mill. Projected completion was reported as on target for late in the second quarter.
