Project Overview

A Surface System
with Depth.

Pucarini is a 100%-owned high-sulfidation gold project 43 kilometres west-northwest of Juliaca. Multiple gold-bearing advanced argillic alteration zones sit within a 3.6 × 1.8 kilometre hydrothermal footprint, where surface geochemistry aligns with resistivity, chargeability and magnetic anomalies.

Southern Peru Miocene Belt

Positioned in an Established Gold District.

The property lies in Lampa Province, Department of Puno, near a region with numerous epithermal gold occurrences and past producing mines. Teck mapped and sampled the property between 2011 and 2015 before Forte’s group acquired the claim in 2018.

First-Pass Drilling
Is Complete.

Forte completed a five-hole, 1,530-metre first-pass drill program at Pucarini. Mineralization was limited: one hole returned anomalous gold, copper and molybdenum values, and no significant mineralization was intersected in the remaining four holes.

Drilling Outcome

Limited Mineralization Intersected.

Drilling confirmed the presence of the targeted hydrothermal system. Assay results returned anomalous gold, copper and molybdenum values in one drill hole only. No significant mineralization was intersected in the other four holes.

Equipment has been demobilized and environmental remediation will be completed. Forte has stated that its primary strategic focus remains on advancing the Alto Ruri gold project.

Forte also announces the completion of a five-hole, 1,530-metre exploration drill program at its 100%-owned Pucarini High-Sulfidation Gold Project (“Pucarini”) in southern Peru. Drilling confirmed the presence of the targeted hydrothermal system. Assay results returned anomalous gold, copper, and molybdenum values in one drill hole, with no significant mineralization intersected in the remaining four holes. Equipment has been demobilized, and environmental remediation will be completed.

Pucarini presented a robust surface anomaly that warranted a first-pass test. We are proud of our team’s ability to execute a safe, cost-effective program at Pucarini. Our primary strategic focus remains on advancing the historically discovered Alto Ruri high-sulphidation gold project,” stated Patrick Elliott, President & CEO of Forte Minerals.

The Pucarini Property

The Pucarini Property consists of a single 1,000 ha (GBT-92) claim centred at 70º 30’ 51” W; 15º 55’ 56” S. The concession was acquired by Globetrotters Resources Peru SAC (“Globetrotters”) in 2018 and is currently held by Cordillera Resources SAC, a 99.99% owned subsidiary of Forte.

The Property is an early-stage high-sulfidation gold project located approximately 43 km west-northwest of the city of Juliaca in the Department of Puno, Peru. The property was mapped and sampled by Teck Resources Peru SAC in the period 2011-2015, and subsequently dropped without having been tested by drilling.

01

Infrastructure

Regular scheduled commercial flight service is available from the Juliaca airport to Lima and other major airports throughout Peru. Access to the property is by unpaved, maintained public roads from Lampa, which is the closest town located 16 km to the east of the Property. Lampa is connected to Juliaca and Arequipa by the national highway network. Most of the population in the vicinity of the Property is involved with agriculture. Lampa is connected to the National electric grid.

Climate

Pucarini has a temperate climate with a wet season from October through March and a dry season from April to September. Temperature averages 6.2 (0.7-17.4 C) in the wet season and 8.8 (-4.4-15.8). Precipitation averages 88.0 mm during the wet season and 14.5 mm during the dry season. Snow is common August through November at higher elevations.

Exploration Model

Four Datasets.
One Coherent Target.

Rock and soil geochemistry, mapped alteration and three geophysical methods converge across the principal target area. The model placed a high-sulfidation gold target above a possible deeper porphyry Au-Cu-Mo target. First-pass drilling of this model was completed in March 2026, with limited mineralization intersected (see Drill Results).

Exploration Target – Geophysics & Geochemistry

  1. Exploration targets identified based on integration of rock and soil geochemistry, chargeability, resistivity, and geology.
  2. Outcrop sampling demonstrates advanced argillic-altered structures are gold-bearing.
  3. High resistivity anomaly suggests a more intense and coherent silicic alteration at depth.
  4. High chargeability anomaly coincides with surface gold geochemistry. The chargability anomaly demonstrates dimensions of 1.5 km in strike length x 600 metres wide and 400 metres deep. This suggests sulphide mineralization could be associated with this high chargeability anomaly.
  5. A high magnetic anomaly centered in the middle of the system suggests a deep rooted porphyry intrusive exists at depth.

The exploration target above was defined before drilling. The March 2026 first-pass drill program returned anomalous gold, copper and molybdenum values in one hole, with no significant mineralization intersected in the remaining four holes.

Surface Expression

Alteration Mapped

Beyond the Core Claim

A Wider District
to Evaluate.

Forte used the hydrothermal alteration signature recognized at Pucarini to evaluate the surrounding Miocene arc. The 2022 follow-up program identified three new occurrences of epithermal mineralization across the regional land package.

Defined Tenure

Mining titles are administered through INGEMMET, and Peruvian concessions are valid for exploration and mining activities.

Tenure and Regulation

Mineral Rights in Peru

The General Mining Law of Peru defines and regulates different stages of mining activities ranging from sampling and prospecting, to development, mining, and processing. The General Mining Law of Peru was changed in the mid-1990’s to foster the development of the country’s mineral resources. The law further defines and regulates different categories of mining activities according to the stage of development (prospecting, exploitation, processing, and marketing).

The Peruvian State does not have free carry rights or options to acquire shareholdings in mining companies. There are no requirements for participation in ownership of mining rights by indigenous persons, groups or entities. Titles over mineral claims are controlled by the Institute of Geology, Mining and Metallurgy (“INGEMMET”). The current status of any mining right can be verified by accessing INGEMMET’s nationwide online concessions database at https://geocatmin.ingemmet.gob.pe/geocatmin/

Mining concessions in Peru are valid for both exploration and mining activities.
