This technical report outlines the recovery methods for the Kitsault Molybdenum Project located in British Columbia, Canada. The proposed process design features a concentrator with a nominal processing capacity of 40,000 tonnes per day based on the 75th percentile ore characteristics. The metallurgical testwork utilized samples from drilling campaigns in 2008 and 2011 to establish the process design criteria for the facilities.

The El Roble Mine process plant operates with a rated nominal throughput capacity of 850 tonnes per day. The processing methods consist of conventional crushing, grinding, and flotation to produce a copper-gold concentrate. The plant utilizes a SAG mill and ball mill circuit followed by multiple stages of flotation cells including OK, Denver, and Sub A styles. Process tailings are deposited in an impoundment facility situated along the banks of the Atrato River, with a dewatering plant implemented for dry stack disposal.

This technical report outlines the proposed recovery method for the Amizmiz property, operated by Maya Gold and Silver. The project is currently in the development stage, with recovery methods based on metallurgical testing performed at Reminex’s Research Centre and Laboratory. The proposed circuit includes gravimetric, flotation, and cyanidation processes, designed to recover gold from the Az and TRN structures. A daily ore mill capacity of 150 t/day has been adopted based on inferred mineral resources and previous results from similar Moroccan mining projects.

This Updated Preliminary Economic Assessment outlines the recovery methods for the Bell Mountain Project deposits, including Spurr, Varga, Sphinx, and East Ridge. Based on surface proximity and preliminary metallurgical test work, valley leach is the anticipated recovery method. The mineralized material features a significant silver content with a 25:1 Ag:Au ratio in some areas.

The San Ramon project, developed by Red Eagle Mining Corporation in Colombia, outlines a proposed processing facility for an underground mining operation. The design focuses on a Carbon-in-Leach (CIL) circuit capable of processing 1,000 tonnes per day of gold-bearing material. The facility includes primary and secondary crushing, ball-mill grinding, agitated leaching, and precious-metal recovery via electrowinning and smelting to produce a gold doré product.

This section of the NI 43-101 Technical Report details the proposed recovery methods for the El Quevar Project, focusing on the processing plant design to recover silver from the Yaxtché sulfide deposit. The design basis is established to process 1,200 tonnes per day of mineralized material sourced from an underground mine. The objective is to produce a bulk silver concentrate with a target grade of approximately 11.5 kg/t Ag through conventional crushing, grinding, and flotation techniques.
