Chief Executive Officer, James Rogers comments:

“Since its inception Turmalina has been focussed on identifying high-quality assets in South America. The Colquemayo project is the culmination of our team's most recent efforts in identifying and acquiring such prospective projects.

Colquemayo represents an exceptional opportunity for our team to create substantial value for Turmalina shareholders. The mineralized system at colquemayo has many similarities to large porphyry systems in the Andes such as Filo del Sol. We intend to advance the understanding of the project through systematic exploration of the exciting epithermal and porphyry copper targets and through an efficient advance from brownfields exploration towards resource definition and initial economic evaluation of the project.

We look forward to commencing permitting and early works as we take over the Colquemayo project. Meanwhile, Turmalina will also continue to advance our San Francisco Project in San Juan, Argentina, where we identified a new epithermal vein camp in 2023."

Vice President, Business Development, Chico Azevedo adds:

“Colquemayo has the characteristics that our team in South America has been looking for in the past few years: a project with economically-relevant drill intercepts with further potential for exploration. The properties cover 6,600 hectares with Cu-Ag-Au mineralization in high sulphidation epithermal systems hosted by phreatomagmatic and hydrothermal breccias emplaced into andesitic volcanic rocks of Paleocene to Pliocene age. Intense hydrothermal alteration has been mapped over an area of 10 km by 3 km.

Previous work by Rio Tinto and Buenaventura identified and drill tested at least three centres with strong hydrothermal alteration and epithermal-style Cu-Ag-Au mineralization, where drilling has proven the presence of intercepts with high grade copper. These intercepts will be followed up after detailed modelling of the mineralized breccia bodies. Drilling and surface mapping and sampling also have identified porphyry-style copper mineralization at the Cairani target, which requires further investigation. A large data set – geology, alteration mapping, geochemistry, spectral data and geophysics - is available and will be systematically evaluated and validated in order to plan the next exploration phases at Colquemayo”.

Location, Access and Infrastructure

The Colquemayo project is located in General Sanchez Cerro province in Moquegua department, near the border with the Arequipa department, in southern Peru. The project area is in the Coalaque district and within the Amata and Palcamayo rural community areas, at elevations between 4,300 and 4,800 meters amsl. The main access to Colquemayo is through the 34-D highway from Arequipa, then MO-516 road and 115 highway, and finally a turnoff to the south for 20 km. The energy supply is secured by a transmission line and a transformation substation located 15 km to the southwest in Puquina town, while a second highway is under construction between the Puquina and Omate. This highway will connect Omate town with Moquegua city and the Ilo sea port (see Figure 1).

Regional Geology

The Cu-Ag-(Au) Colquemayo project is situated in the late Miocene to Pliocene epithermal belt in southern Peru, hosted by volcanic units of the early Miocene to Pliocene age Maure and Barroso Groups. At a regional scale, the project is spatially related to upper Cretaceous to Pliocene intrusions and a major regional fault that put in contact the Coastal Basal Complex (neo-Proterozoic) with the Mesozoic sedimentary units (Figure 2).

Colquemayo is located to the east of the productive Cu-Mo Paleocene to Eocene porphyry belt hosting the copper mines of Cerro Verde, Cuajone, Quellaveco and Toquepala, and to the west of the Au-Ag Late Miocene to Pliocene epithermal belt with important projects and mines such as San Gabriel, currently under construction, and the Aruntani mining district (>2 Moz Au produced)

Previous Work, Geology and Mineralization

Previous work by Rio Tinto and Buenaventura between 2003 and 2014 includes detailed geological mapping and intensive surface geochemistry with ~9,800 rock chip and ~1,500 channel samples. Detailed topography (1 m resolution) and geophysical surveys (magnetometry, chargeability and resistivity) have been completed at two of the hydrothermal centres identified to date.

Initial surface mapping and sampling identified several breccias that returned significative gold, silver and copper assays. These breccias, when drill tested at depth, proved to be phreato-magmatic and hydrothermal breccias cutting a thick sequence (~600 meters) of andesitic volcanic and volcaniclastic rocks. Alteration mapping shows the zonation typical of a high-sulphidation epithermal system, including argillic alteration with kaolinite and dickite, advanced argillic alteration with quartz and alunite, and some deeper pyrophyllite zones, along with zones of massive and vuggy silica (see figures 3 and 4).

In 2003 Rio Tinto drilled 16 diamond drill holes in several targets, including Amata, Cairani and Coripuquio, with the best intercepts returned from Amata and Coripuquio. Between 2010 and 2014 Buenaventura drilled 67 diamond drill holes, focusing on the Amata, Coripuquio and Yanarico targets. The best results were obtained at Amata and Coripuquio. At Amata, enargite-pyrite rich breccias were the main hosts for mineralization (see figures 5, 6, 14, 15 and 16). At Coripuquio some intercepts of oxidised breccias returned gold values of 0.5 to 1 g/t Au, indicating potential for low-grade oxide gold for an open pit/heap leach operation and requires further drilling for proper evaluation (see figure 7 and 15). Sixteen holes have tested and confirmed the presence of mineralization between 400 and 600 meters depth. In total 83 diamond drill holes for ~27,000 meters were completed. All surface and core samples (~13,700 samples) have complete geochemical analyses – fire assay for gold and ICP for multi-elements, along with systematic spectral analyses for mineral identification.

The dimensions of the hydrothermal centres are at least 5 km by 2 km for the Amata-Cairani-Coripuquio centre, and 3 km by 2 km for the Yanarico system. Drilling was concentrated in the areas where the advanced argillic alteration and massive and vuggy silica were better exposed. The available mapping shows that this alteration system is continuous for at least 10 km along the southern portion of the property. Preliminary field reconnaissance conducted by the Turmalina geological team confirmed the presence of similar alteration patterns with related potential mineralization between Coripuquio and Yanarico (see figures 3 and 4).

The mineralized breccia bodies include monomitic and polymitic breccias with a pyrite-enargite +barite cement. Locally there is abundant silica flooding. Enargite is the main copper mineral in most of the drilling completed to date (figures 13 and 14), but at some holes (e.g. hole AM-14-03) at Cairani, chalcocite and covellite are the main copper minerals. This mineralogy, associated with the presence of wormy textures, typical porphyry-style veining, dacite porphyry intrusives, elevated molybdenum and lower arsenic, suggests a transition towards porphyry-style mineralization at Cairani, that still requires drill testing (figures 9, 11, 12 and 13.).

The systematic spectral geology carried out in the drill core identified a pyrophyllite zone (figure 8) that is coincident with a portion of the best hole drilled at the project (COQ10-36), and also indicates a potential zonation towards porphyry-style mineral assemblages at depth.

Colquemayo Exploration Plan

It is anticipated that the permitting process to resume drilling in Colquemayo will take 14 to 18 months. During this timing, a detailed core review is planned to build geological models for the breccia bodies with significant drill intercepts, including:

• Validation of the logged geology using the geochemical database.

• Determining the geometry of the breccia bodies based on surface mapping and drill core information.

• Review, modelling and interpretation of the geophysical data.

• Mapping of alteration zones to define potential source areas – including porphyry intrusions with Cu-Mo mineralization.

Exploration will also focus on areas in the property outside the three centres of hydrothermal alteration identified and drill tested to date. In some of these areas argillic and advanced argillic alteration have been recognized locally, with limited exposure because of overlying lower temperature alteration assemblage (chlorite, epidote and carbonate). These areas may represent less eroded parts of epithermal systems, with potential for definition of new hydrothermal centres for initial drilling. Additional geophysics to cover the remaining part of the property will also be considered.
