Three intrusive centers have been identified within the mining property: Dos Quebradas, Mandeval-Centro and La Cumbre. They are copper-poor gold porphyry-type systems in which the intermediate argillic conclusion locally overprints an early potassic assemblage and stockwork of quartz veins, where gold is found in altered dioritic intrusions and contact zones. The Dos Quebradas and Centro-Mandeval intrusives were verified with some drilling, pending their characterization and development of the filling program to determine their mining potential. Additionally, to the south of the property, epithermal-type mineralized structures and the presence of mineralized breccias have been found. The La Cumbre Project is located along the eastern margin of Colombia’s physiographic Western Cordillera. The region is underlain by a highly complex basement known as the Romeral Terrane, which may be characterized as a tectonic mélange. The basement took form when Middle to Upper Mesozoic-aged volcanic and sedimentary oceanic rocks collided with, and were accreted to, the northern Andean paleo-continental margin, beginning in the Early Cretaceous. The resulting suture is known as the Romeral fault system and the mélange can be traced for over 1,000 km along the northern Andes. The La Cumbre and surrounding area is underlain by four principal rock units. These include: 1) a basement complex consisting of mafic and ultramafic oceanic volcanic rocks and granitoid intrusive rocks belonging to the ........

The mining method defined for La Cumbre Project is an open pit method with a predominant bank height of 6 meters, 12-meter ramp width two way only and inter-ramp angles between 38° and 43°.

The project is segmented into two stages involving different capital investments in order to meet the infrastructure requirements of each stage of the project's LoM.

The first stage corresponds to the mining of the ore contained in the oxide and transition zones, which will be agglomerated and processed in leach pads at a throughput of 15 ktpd. At this stage of the project, the stripping ratio is an average of 0.28, allowing for the disposal of the waste dump and the stockpile in Matecaña area during the 5 years of this stage; that is, the transport of ore and waste will be done through the overland conveyor to maximize its use and take advantage of its regenerative capacity.

The second stage involves the mining of the primary sulfide zone that will be processed in a flotation and gravimetry plant whose ramp up will be in the 5th year and will last until the 14th year of the project. During this stage, starting in year 6, the stripping ratio is an average of 0.49 and the dumps will be available north of the pit, this will allow us to increase the throughput to 30 ktpd transported by the overland conveyor.

The preferable mining and processing methods for La Cumbre is conventional open pit mining followed by heap leaching process for oxide and tran ........
