The La Mina Project lies within the Middle Cauca Belt of Miocene-age volcano-plutonic rocks of central Colombia. This belt hosts several significant porphyry gold or copper-gold disseminated deposits such as La Colosa, Titiribí, Quebradona, and Quinchia, as well as large epithermal gold districts such as Marmato.

Localized intrusive centers (e.g., La Cantera, Middle Zone, El Limon, and La Garrucha) comprise a series of intermediate composition porphyries and related intrusive (emplacement) breccias.

LA CANTERA PROSPECT
The principal ore minerals associated with the Au-Cu porphyry mineralization at La Mina are chalcopyrite and lesser bornite, both with associated gold mineralization. Secondary copper minerals (chalcocite, azurite, malachite and chrysocolla) do occur locally in the upper portions of the La Cantera prospect. Overall gold mineralization greater than 0.3 g/t Au is sulfide-poor and typically contains less than 1% total sulfides. In this type of mineralization chalcopyrite ± bornite are more abundant than pyrite.

MIDDLE ZONE PROSPECT
The principal ore minerals associated with the Au-Cu porphyry mineralization at Middle Zone consist of chalcopyrite, pyrite, and, in very rare cases, bornite. Secondary copper minerals (chalcocite, cuprite, malachite and chrysocolla) do occur locally in the shallow portions at Middle Zone prospect; they represent supergene alteration of primary hypogene copper mineralization. Generally, gold ........

According to PEA evaluates conventional surface mining methods using surface drill and blast techniques with off-highway haul trucks and front-end loaders to be appropriate for the La Mina Project.

A 24-month stripping campaign is estimated and scheduled before the mine starts producing mineralized material for the process plant. It is anticipated that these activities will be performed by third-party contractors. The initial stripping phase of the mine plan is comprised of steep terrain that will require smaller equipment and will be slower than production mining activities. No mineralized material is expected during the stripping campaign; however, any mineralized material encountered will be stockpiled near the process plant.

After the 24-month stripping campaign, production mining begins at a rate of 46k tonnes per day, delivering and sustaining 10k tonnes per day of mineralized material to the process plant for 10 years.

During the first 3 years, most of the process plant feed comes from the Middle Zone pit, while enabling La Cantera to be prepared as it has a higher strip ratio. Starting in year 4, the core of the Middle Zone pit mineralized zone is exposed and becomes the primary source for process plant feed for years 4 through 9, leaving La Cantera idle until the last 2 years of mining.

Once the mine operation is in full production in year 1, it is estimated all material will be drilled and blasted prior to loading into h ........
