Los Andes Copper Ltd. Receives Final Molybdenum Assessment Results and Concentrate Specifications for the Vizcachitas Project

Los Andes Copper Ltd. (TSXV: LA) ("Los Andes" or the "Company") is pleased to announce that as a part of the ongoing Pre-Feasibility Study ("PFS") at the Vizcachitas Project in Chile ("Vizcachitas" or the "Project"), it has received molybdenum flotation results for the first 12 year samples, confirming the molybdenum recovery assumptions formed in the 2019 Preliminary Economic Assessment(" PEA") and confirming that the Vizcachitas operation will produce clean concentrates.

As a part of the PFS metallurgical test work, representative samples of the first 12 years of operation were sent to SGS Minerals for rougher, cleaner-scavenger, and selective rougher copper-molybdenum flotation.

Based on the PFS test work results and for the first 12 years of operation, the molybdenum recoveries are 90.3% in the rougher stage, 95.8% in the cleaner-scavenger stage, and 90.6% in the copper-molybdenum selective flotation; resulting in a projected overall molybdenum recovery of 76%, a slight improvement from the 75% recovery assumed in the PEA.

Furthermore, analysis for the final copper concentrates confirmed that Vizcachitas will produce clean concentrates. Projected results show that final copper concentrate grades are between 22.9% and 24.4% copper, and a credit may be obtained for silver at grades between 46 to 65 grammes per tonne. No elements are present at penalty levels in the copper concentrates as the grades for antimony and bismuth are below 0.04% and 0.01% respectively, first 12 year weighed average of arsenic grades is 0.16% and mercury grades are approximately 5.2 ppm.

Fernando Porcile, Executive Chairman of Los Andes, commented:

"We are delighted with the results of the PFS metallurgical test work as they have confirmed and improved the economical assumptions made in the PEA report. The results represent yet another accomplishment for the development of Vizcachitas, following the recent investment from Queen's Road Capital, the award of the environmental approvals for the drilling programmes and further metallurgical test work confirming a copper recovery rate of 91.4%. These updates illustrate the asset's significant potential.

"The outcome of this metallurgical study has shown an improvement in the overall recoveries and it is encouraging to see that it has also confirmed the use of eco-friendly technologies such as HPGR and dry-stacked tailings, which are important in the development of sustainably produced copper for the green transition. We look forward to providing advancements as we move to complete our PFS at Vizcachitas."

About Los Andes Copper Ltd.

Los Andes Copper Ltd. is a development company with a 100% interest in the Vizcachitas project in Chile ("Vizcachitas" or the "Project"). The Company is focused on progressing the Project, which is located along Chile's most prolific copper belt, into production.

Vizcachitas is a copper-molybdenum porphyry deposit, located 120 km north of Santiago, in an area of good infrastructure. The N.I. 43-101 compliant Preliminary Economic Assessment, delivered in June 2019, highlights that the Project has a post-tax NPV of USD$1.8 billion and an IRR of 20.77%, based on a USD$3 per pound copper price. The Project has a Measured Resource of 254.4 million tonnes at a grade of 0.439% copper and an Indicated Resource of approximately 1.03 billion tonnes at a grade of 0.385% copper. Please refer to the technical report dated June 13, 2019, titled "Preliminary Economic Assessment of the Vizcachitas Project", prepared by Tetra Tech.

The PEA is preliminary in nature, it includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the PEA will be realized.

The Company is currently advancing the Pre-Feasibility Study of the Project. With the incorporation of a highly experienced management team, the Project is incorporating changes to position itself on the forefront of global environmental trends for mining. The conversion to dry-stacked filtered tailings will result in a substantial reduction in water consumption and will discard the use of tailings dams, thus reducing the Project's footprint, environmental impact and seismic risks.

Additionally, there is significant exploration upside at Vizcachitas with the potential to increase the resource base beyond the initial 45-year mine life modelled in the PEA. Part of this upside has been further delineated in the geological mapping and geophysics work program completed during the 2020 Chilean winter season.

Los Andes Copper Ltd. is listed on the TSX-V under the ticker: LA.

What's the Next US Copper Mine? 27 Copper Projects to Watch

Companies with upcoming copper mines in the US could be poised to benefit from tailwinds in the sector, including supply deficits and the Trump administration's promises to cut "red tape" for critical minerals projects.

Copper demand is climbing quickly in recent years because of the rapid urbanization of the global south as well as the developing energy transition sectors. However, current copper mines are increasing in age and there is a lack of new copper mines to replace them, both due to limited greenfield exploration and long permitting times.

This has put the world's copper supply in a difficult situation, and experts expect to see deficits begin to emerge in 2025.

Finlay Minerals stakes the JJB Property - within the Bear Lake Corridor of British Columbia

Finlay Minerals stakes the JJB Property - within the Bear Lake Corridor of British Columbia

finlay minerals ltd. (TSXV: FYL) (OTCQB: FYMNF) ("Finlay" or the "Company") is pleased to announce the staking of 9 mineral claims covering 15,453 hectares (approximately 154 km²) in the northern Bear Lake Corridor of British Columbia . The JJB Property is named in honour of Finlay's Founder, John J. Barakso who was an early advocate for the potential of the Bear Creek Corridor.

Figure 1. New JJB Property location and expanded SAY Property boundary. (CNW Group/Finlay Minerals Ltd.)

JJB PROPERTY:

The JJB Property is located within a highly prospective 135-kilometer-long belt in the Stikine Terrane, which hosts several significant copper (Cu) and silver (Ag) showings and prospects. Noteworthy nearby projects include Zimtu Capital Corp.'s Copperline Project and Doubleview Gold Corp.'s Red Spring Project. Additionally, porphyry projects along the Bear Lake trend include Imperial Metals' Cu-Mo Porphyry Bear Lake Project, American Eagle Gold's Cu-Au-Mo ± Ag NAK Project, Amarc Resources Ltd.'s DUKE Project, and HDI Quartz Mountain's Cu Porphyry Jake Project.

The JJB area has geology similar to that of the deposits found in the Bear Lake Corridor. Three main copper showings have been identified on the property: Squingula, Quin, and Pat. The Squingula and Quin showings are located near an Eocene intrusion on the west side, characterized by a coincident magnetic high. This magnetic high is surrounded by a low that corresponds with an iron oxide anomaly, potentially indicative of a porphyry target. Both the intrusion and the magnetic and iron oxide signatures are associated with a multi-element geochemical anomaly identified through limited sampling. Mineralization appears to be influenced by major northwest-trending structures and east-west cross structures, with known mineralization occurring at the intersections of these structures.

In 2025, exploration work at the JJB will focus on expanding the geochemical anomalies within the gossanous magnetic low surrounding the magnetic high. Priority will be given to an airborne magnetic survey, along with prospecting and soil sampling.

Details on the JJB Property can be found in the JJB Property Technical Presentation and in the Properties section of the Company website at www.finlayminerals.com .

SAY PROPERTY:

Lying 4 km south of Finlay's new JJB Property, work continues on the SAY Property, which has recently been expanded with additional staking to the north and south. The SAY Property now totals 26,202 hectares. The SAY Property was acquired in 2024, and an inaugural field program focused on chip sampling and mapping along the 4.3-kilometer-long SPUR Trend. This led to the discovery of the AG Zone and confirmed the continuity of high-grade Cu-Ag mineralization in the East Breccia Zone.

The SPUR is a high-grade Cu-Ag structural vein and breccia target that extends for 4.3 km along the north-northwest Tsaytut Spur ridge * .

The SHEL target area is a Cu-Mo porphyry identified through historic mapping and drilling. SHEL mineralization is reported to be associated with veining and breccias within quartz-feldspar porphyry dikes and lies on the western margin of an unexplored 3 km x 2 km magnetic high * . Historical assays and airborne magnetic data indicate the potential for the expansion of known mineralization in these two target areas.

In 2025, exploration work at the SAY will aim to expand the mineralized footprint of the SPUR and SHEL targets through geological mapping, soil sampling, and an airborne magnetic survey.

Details on the SAY Property, can be found in the SAY Property Technical Presentation and in the Properties section of the Company website at www.finlayminerals.com .

5 Best-performing Copper Stocks on the TSX in 2025

Over the past year, copper prices have reached record highs on two occasions, with the most recent instance being on March 26, when the metal soared to US$5.26 per pound.

These high prices stem from an increasingly tight copper market, driven by rising demand from population growth and migration in the global south, as well as growing pressures from the energy transition.

This situation is compounded by a limited number of greenfield projects that would introduce new deposits, as opposed to brownfield projects that merely extend the life of existing mines.

The first quarter of the year also witnessed some panic buying, as traders moved inventories into the US in anticipation of tariff-related price increases. Interest in companies developing US copper mines has increased as well as new US President Donald Trump looks to expedite critical metals projects.

Against that backdrop, how have TSX-listed copper companies performed? Learn about the top five best-performing copper stocks in 2025 by year-to-date gains below. Data for this article was retrieved on April 7, 2025, using TradingView's stock screener, and only companies with market capitalizations greater than C$50 million are included.
