The newly identified target lies to the west of the primary Cambaya I and Cambaya II targets and is the result of extensive reconnaissance efforts carried out within Zone 1. This is the first phase of the broader regional exploration spanning three (3) distinct zones of sediment geochemical anomalies ('BLEG') across the approximately 17,000 hectares of the Curibaya project.
This high-grade target developed along the Sambalay Chico fault, is an integral part of the broader Incapuquio fault system where polymictic breccias have been identified with values up to 42.20 g/t Au, 651 g/t Ag, and 6.12% Cu related to silicified fragments. A quartz structure, related to the stress control of the Incapuquio fault, with sulfides 0.30 metres (m) wide , has also been identified with values up to 1,360 g/t Ag, 4.05 g/t Au and 0.13% Cu.
Additionally, a new mineralized vein corridor has been identified, referred to as the Sambalay Chico Corridor, extending up to 1.5 kilometres (km) in length, and features values up to 139 g/t Ag and 2.56 g/t Au. It also reveals anomalies, registering at 400 ppm arsenic (As), while maintaining Ag/Au ratios that average around 100, suggesting that Zone 1 occupies the upper levels of an epithermal system. With the identification of this new corridor situated at an elevation of 2,200 m, the Curibaya project now hosts a current tally of seven (7) mineralized corridors, demonstrating its strong exploration potential.
A Message from
As we continue to explore beyond these robust targets, we've consistently encountered high grades of silver, gold, and now copper. These findings stand as a testament to the unique nature of this exploration endeavor. In preparation for drilling, our team is excited by our ongoing efforts to unearth new areas of high-grade outcropping mineralization, which continues to expand the potential for discovery at Curibaya, situated on one of the world's most prolific mining trends.'
Zone 1 Exploration Findings, Geochemical Insights, and Terraspec
Zone 1 has emerged as a focal point of Tier One's recent exploration efforts following the geological team's comprehensive BLEG sampling campaign in 2021, which identified significant anomalies in copper (> 40 ppm), molybdenum (> 1.30 ppm), and gold (> 3.5 ppb).
Tier One's exploration activities within Zone 1 were strategically oriented towards identifying disseminated mineralization centers and unveiling new structures and corridors. The Company collected a total of 116 rock chip samples at a grid spacing of 150 m x 150 m, supplemented by 25 rock chip-channel samples and 13 trenches with 57 channel samples.
These efforts showcase strong exploration potential at the Curibaya project, identifying two (2) new significant targets. The first, known as the 'Del Filo target,' is closely linked to intrusive dikes and polymictic breccia outcrops measuring 30 m x 30 m. These formations comprise intrusive rock fragments and silicified components hosting valuable gold, silver, and copper mineralization. The second target, known as 'Sambalay Chico,' is associated with a new vein corridor stretching approximately 1.5 km and features silicified structures housing drusy and colloform quartz veins with widths of up to 2 m.
Lithologically, Zone 1 corresponds to a composite of mixed volcanic-sedimentary volcanic rocks, forming a volcanic edifice characterized by tuffs and volcanic breccias with andesitic, rhyolitic, and dacitic compositions. Stratigraphically, these rocks align with the
Controlling these two targets are two principal fault systems, the Huanacos fault with an E-W orientation and the Sambalay Chico fault with an NW-SE orientation. These structural controls are integral components of the larger Incapuquio fault system, renowned for hosting significant copper deposits like Toquepala, Quellaveco, and Cuajone.
Geochemical Insights
The Del Filo target demonstrates geochemical data indicating high-grade values of 42.20 g/t Au, 651 g/t Ag, and 6.12% Cu. Additionally, values of 8.19 g/t Au, 26 g/t Ag, and 0.27% Cu have been linked to silicified fragments featuring malachite, chrysocolla, and dark brown earthy oxides). Noteworthy among these findings is a silicified rock fragment containing manganese and copper oxides, displaying a value of 3.32 g/t Au and 0.1% Cu. Moreover, a 0.30 m wide quartz structure enriched with sulfides has been identified, showcasing values reaching as high as 1,360 g/t Ag, 4.05 g/t Au, and 0.13% Cu. Indications of other elements such as arsenic have risen to 900 ppm, while antimony (Sb) values reach 40 ppm and bismuth (Bi) values extend to 6 ppm.
The new Sambalay Chico Corridor has unveiled values up to 297 g/t Ag and 1.8 g/t Au within a 1-m wide channel sample, further enhanced by a 1 m channel sample presenting 120 g/t Ag and 1.38 g/t Au. The presence of volatile elements like arsenic up to 400 ppm has been identified, while Ag/Au ratios exhibit an average range of 50 to 100-a characteristic consistent with the upper tiers of an epithermal system.
Within
Zone 2 and Future Prospects
Presently, Tier One's efforts are focused on reconnaissance, giving the Company an opportunity to identify new corridors. As these corridors undergo comprehensive geochemical sampling, Tier One will release updates when complete geochemical sample results are received.
Following the thorough recognition of these areas featuring BLEG anomalies, involving semi-detailed geological mapping, rock sampling, and Terraspec studies, the Company's next steps involve extensive field work. This preparatory work is geared towards delineating targets for future drilling efforts.
The drilling plan in the Cambaya area remains intact, with a focus to drill after raising the necessary capital to support the program.
