In addition to its operating El Bagre Mill, Soma owns the 225 tpd Limon Mill which is located 47 km south of the El Bagre Mill. The Limon Mill has been on care and maintenance since 2020 but is available to be restarted when production from the Cordero Mine exceeds the capacity of the El Bagre Mill.
The Limon Mill operates similarly to the El Bagre Mill with two-stage crushing, ball milling, gravity concentration, flotation, cyanidation, Merrill Crowe precipitation, and smelting to produce doré. The mill was upgraded in 2017 to a capacity of 225 tpd and is permitted for up to 400 tpd.
Soma has formalized agreements with three of the (formerly illegal) small miners near the El Limon Project and anticipates formalizing additional miners in the future. This allows them access to modern mining and processing technologies, including eliminating the need to use mercury to extract gold. It is anticipated that these small miners will provide some of the feed for the El Limon mill when it is restarted.
