Los Andes Copper Files Positive PFS for Vizcachitas With a US$2.77 Billion Post-Tax NPV and 24% IRR

Los Andes Copper Files Positive PFS for Vizcachitas With a US$2.77 Billion Post-Tax NPV and 24% IRR

Los Andes Copper Ltd. (TSXV: LA) (OTCQX: LSANF) ("Los Andes" or the "Company") is pleased to announce further that it has now filed the pre-feasibility study at its 100% owned Vizcachitas Project ("Vizcachitas" or the "Project") which was the subject of its news release of February 23, 2023 (the "PFS"). The PFS, titled "Vizcachitas Project Pre-Feasibility Study Valparaíso Region, Chile NI 43-101 Technical Report" dated March 30, 2023 with an effective date of February 20, 2020 was prepared for Los Andes by Tetra Tech, and has been filed under the Company's profile at www.sedar.com.

Highlights of the PFS include:

  • Proven and Probable Reserves of 1.22 billion tonnes at 0.36% copper, 136 parts per million ('ppm') molybdenum, 1.1 grammes per tonne ('g/t') silver, which equates to a copper equivalent ('CuEq') grade of 0.40%.
    • Proven Reserves of 302 million tonnes (Mt) at 0.41% copper, 135 ppm molybdenum, 1.2 g/t silver;
    • Probable Reserves of 918Mt at 0.34% copper, 136 ppm molybdenum, 1.1 g/t silver.
  • A 16% increase in Measured and Indicated Resources from the Company's Preliminary Economic Assessment dated June 13, 2019 to 14.8 billion pounds ('lbs') CuEq.
    • Measured Resources of 2.605b lbs copper, 84 million lbs molybdenum and 11 million ounces ('Moz') silver;
    • Indicated Resources of 10.416 billion lbs of copper, 442 million lbs of molybdenum, and 43Moz of silver;
    • and increase of Inferred Resources by 130% to 15.4 billion lbs CuEq (13.747 billion lbs copper, 495 million lbs molybdenum, 55Moz oz silver).
  • Initial Life of Mine ('LOM') of 26 years producing 8.763 billion lbs copper, 273.3 million lbs molybdenum and 32.7Moz silver, based on a new plant design with a mill throughput of 136,000 tonnes per day.
  • Annual average copper production of 183,017 t (LOM average of 152,883t).
  • A US$2.776 billion after-tax net present value (NPV) using an 8% discount rate and an internal rate of return (IRR) of 24.2% at US$ 3.68/lb copper, US$12.90/lb molybdenum and US$21.79/oz silver, with an estimated initial capital cost of US$2.441 billion, a construction period of 3.25 years and a payback period of 2.5 years from initial production.
  • Use of desalinated water, eliminating the need to draw on continental water; using dry stacked filtered tailings reduces water consumption by approximately 50% and eliminates the need for a tailing dam, minimizing seismic and environmental risks.
  • Use of high pressure grinding roll (HPGR) technology, reducing power consumption by approximately 25% from the previous design. Scope 1 CO2 emissions are projected to be 1.02 h CO2e/t CuEq, and Scope 2 emissions are projected to be 0.

The PFS assumed copper, molybdenum and silver prices of US$3.68/lb copper, US$12.90/lb molybdenum and US$21.79/troy ounce silver, resulting in the Mineral Resources and Mineral Reserves presented below. Copper contributes 88% to the projected net revenue from the Project, followed by molybdenum with 10% and the balance being silver credits in copper concentrate.

OUTCROP SILVER ANNOUNCES PARTNER FUNDED MAIDEN DRILL PROGRAM AT THE PEARL COPPER PROJECT, ARIZONA

OUTCROP SILVER ANNOUNCES PARTNER FUNDED MAIDEN DRILL PROGRAM AT THE PEARL COPPER PROJECT, ARIZONA

Outcrop Silver & Gold Corporation (TSXV:OCG, OTCQX:OCGSF, DE:MRG) ("Outcrop Silver") is pleased to announce the commencement of the maiden drill program at the Pearl Copper Project located in Arizona United States . The drilling campaign will be fully funded by Golden Mile Resources Limited (ASX: G88), whereby Golden Mile is currently earning a 51% interest through funding this A$2 million maiden drill program. Outcrop Silver retained a 1% net smelter return (NSR) royalty.

Outcrop Silver logo (CNW Group/Outcrop Silver & Gold Corporation)

Highlights

  • Outcrop Silver advances the Pearl Copper project through an earn-in agreement with Golden Mile Resources (ASX:G88). Program fully funded by Golden Mile .
  • The Pearl project is located in the prolific Laramide porphyry copper district, which is responsible for 70% of the United States of America's copper production.
  • All drilling permits secured from the Bureau of Land Management (BLM) and the Arizona State Land Department (ASLD).
  • The maiden drill program to test high-grade copper-silver-gold targets at the Odyssey and Ford prospects has commenced.

" Golden Mile's fully funded drill program moves Pearl forward at no cost to Outcrop Silver and exemplifies our strategy of unlocking value from non-core assets while we focus capital on expanding the high-grade Santa Ana silver project in Colombia ," stated Ian Harris , President & CEO of Outcrop Silver.

The Pearl Copper project is located in the Laramide porphyry copper district, one of the most prolific copper-producing regions globally, accounting for approximately 70% of U.S. copper production. The project sits immediately north of BHP's past-producing San Manuel-Kalamazoo Mine and along the trend with Capstone Copper's active Pinto Valley Mine, benefiting from exceptional infrastructure and a skilled local workforce.

Following the receipt of all required exploration permits, including the Notice of Intent (NOI) from the BLM and the Special Land Use Permit (SLUP) and Geologic Field Operation Plan (GFOP) from the ASLD, drilling has commenced. This maiden drill program consists of 14 to 16 reverse circulation (RC) holes totaling up to 1,800 metres, and will test two priority targets.

Transaction

On September 12, 2024 Golden Mile purchased an option on Pearl for A$100,000 (Australian Dollars) with Outcrop Silver retaining a 1% NSR royalty. Golden Mile has the option to earn-in to 51% by funding A$2,000,000 in exploration expenditures by September 12, 2027 . Golden Mile may also earn an additional 34% by funding an additional A$10,000,000 in exploration expenditures within 5 years. Upon completing the earn-in a joint venture will be formed with both parties funding proportionally. If either party dilutes below 10%, their interest will convert to an additional 1% NSR royalty. At such time that a JORC compliant resource achieves 750,000 tonnes of contained copper at a minimum grade of 0.3%, Golden Mile will pay Outcrop Silver A$2,000,000 .

The Pearl Copper project was acquired through the amalgamation with Zacapa Resources. Zacapa's portfolio also included the Kramer Hills brownfield oxide gold project in San Bernardino, California and the South Bullfrog, gold project in Beatty, Nevada adjacent to Anglo Gold's Silicon project.

Group Eleven Intersects 12.0m of 2.30% Cu and 560 g/t Ag, Including 6.4m of 3.72% Cu and 838 g/t Ag, Demonstrating High-Grade Copper and Silver Potential at Ballywire

Group Eleven Intersects 12.0m of 2.30% Cu and 560 g/t Ag, Including 6.4m of 3.72% Cu and 838 g/t Ag, Demonstrating High-Grade Copper and Silver Potential at Ballywire

Group Eleven Resources Corp. (TSXV: ZNG) (OTC Pink: GRLVF) (FSE: 3GE) ("Group Eleven" or the "Company") is pleased to announce assay results from four new holes from the ongoing drill program at the Company's 100%-owned Ballywire zinc-lead-silver discovery ("Ballywire"), PG West Project ("PG West"), Republic of Ireland.

Highlights:

  • 25-3552-31, a 65m step-out hole, intersected two strongly mineralized horizons:
    • Cu-Ag horizon (starting at 348.7m downhole)
      • 19.9m of 1.46% Cu and 356 g/t Ag, including
      • 12.0m of 2.30% Cu and 560 g/t Ag, including
      • 6.4m of 3.72% Cu and 838 g/t Ag
    • Zn-Pb-Ag horizon (starting at 297.0m downhole)
      • 47.1m of 4.5% Zn+Pb (3.1% Zn and 1.4% Pb) and 22 g/t Ag, including
      • 25.9m of 7.4% Zn+Pb (5.1% Zn and 2.3% Pb) and 35 g/t Ag, including
      • 12.9m of 11.0% Zn+Pb (7.7% Zn and 3.2% Pb) and 57 g/t Ag, including
      • 3.7m of 20.4% Zn+Pb (15.8% Zn and 4.6% Pb) and 151 g/t Ag
  • Up to 10.45% Cu (over 0.80m) and up to 1,880 g/t Ag (over 0.86m) intersected in the Cu-Ag horizon; to the Company's knowledge, this represents the highest-grade Ag intercept in Ireland over the last >60 years (by any operator) and similarly, one of the highest-grade Cu intercepts
  • Cu-Ag horizon consists of replacement-style mineralization along the base of the Waulsortian Limestone in proximity to a fault structure; mineralization appears to consist mostly of tennantite-tetrahedrite (detailed mineralogy work to be undertaken in due course)
  • Noteworthy is the presence of elevated antimony in the Cu-Ag zone, grading 0.27% Sb within the above 6.4m interval (including 0.80m of 10.45% Cu, 1215 g/t Ag and 0.83% Sb)
  • This hole expands the footprint of the 2.6km long discovery trend by at least 65m down-dip, to a total of at least 170m down-dip along this section (and remains open further down-dip)
  • Drilling continues at Ballywire with two rigs testing (i) the NE extension and (ii) 1.3km ENE of the Ballywire discovery in the vicinity of the prospective 'D' gravity-high anomaly; a third rig was added this week, testing the deeper Cu-Ag target (below the Waulsortian Limestone)

"Intersecting spectacular copper-silver grades over significant thicknesses is a pivotal moment for the Ballywire discovery," stated Bart Jaworski, CEO. "These results not only strongly point to a stratigraphically deeper Cu-Ag horizon but also represent a proof of concept that substantial grades and thicknesses of copper and silver exist at the discovery, in addition to excellent grades of Zn-Pb. The growing presence of critical minerals at Ballywire, namely, copper, germanium and now potentially antimony, highlights the rising strategic importance of this discovery for Ireland, the EU and our shareholders. With today's Cu-Ag milestone, continued drilling to the NE and along our prospective 6km trend, plus the start of drilling with our third rig, we are poised to further grow shareholder value as the year progresses."

New Step-Out Holes at Ballywire Discovery

The Ballywire prospect at the Company's 100%-owned PG West Project in Republic of Ireland, represents the most significant mineral discovery in Ireland in over a decade. First announced in Sept-2022, the discovery has 52 holes drilled and reported by Group Eleven to date, including the most recent four holes (25-3552-30, -31, -32, and -33) reported today (see Exhibits 1 to 7).

High-grade Zn-Pb mineralization from 25-3552-31 (see Page 1 and Exhibits 1 to 4) consists predominantly of sphalerite, galena and pyrite. High-grade Cu-Ag mineralization in this hole consists of suspected tennantite/tetrahedrite, chalcopyrite, sphalerite, galena and pyrite along and/or close to the base of the Waulsortian Limestone (see Exhibit 1). Noteworthy is the presence of elevated antimony within the Cu-Ag zone. For example, the 6.39m interval below, grading 3.72% Cu and 838 g/t Ag, also grades 0.27% Sb (including 0.80m of 10.45% Cu, 1215 g/t Ag and 0.83% Sb).

Note: True width of the mineralized interval in hole 25-3552-31, as a percentage of the down-hole interval, is estimated to be 50-70%; for photographs of Cu-Ag rich core, see Appendix and www.groupelevenresources.com.

Three other holes released today were drilled in a 150m gap to the NE of 25-3552-31 (25-3552-30, -32 and -33; see Exhibit 2). Hole 25-3552-30 returned nil mineralization, 25-3552-32 returned three intervals of mineralization up to 0.94m of 2.4% Zn+Pb (0.9% Zn and 1.5% Pb) and 8 g/t Ag, and 25-3552-33 returned three intervals of mineralization up to 0.82m of 2.9% Zn+Pb (1.1% Zn and 1.8% Pb) and 7 g/t Ag. These zones of mineralization are narrower and weaker than those at the main discovery trend but generally in line with recent holes drilled further to the ENE (see holes G11-3552-24, -26 and 28 in news release dated 25-Mar-2025). Disseminated copper mineralization, as well as, mineralized veins and fractures, is strengthening towards the north, suggesting massive sulphide mineralization may be present further north (see northern-most purple line in Exhibit 4). A second mineralized trend is also emerging to the south where the interpreted Cu-Ag rich 'feeder' fault pierced by drilling along the main discovery trend appears to correlate with mineralization approx. 350m along strike to the ENE, intersected in G11-3552-08 (see solid and dashed purple lines in Exhibit 4). Drilling is ongoing in the NE area to test the above targets.

Copper-Silver Target

Today's results add to a growing body of evidence that support the interpretation of a Cu-Ag 'feeder' fault parallel to and spatially associated with the main Zn-Pb-Ag discovery at Ballywire (see Exhibit 4). With up to 10.45% Cu and 1,880 g/t Ag in a mineralized horizon near a steeply dipping structure, mineralizing fluids are interpreted to have emanated from deeper in the sedimentary sequence (see Exhibit 5). Meanwhile, the stratigraphy of the region suggests that the Lower Limestone Shale horizon exists approximately 100-200m below the discovery horizon (base of the Waulsortian Limestone). This horizon hosts four well known Cu-Ag historic occurrences in the surrounding area (see Denison, Oola, Gortdrum and Tullacondra in Exhibit 8, located approx. 5km, 9km, 10km and 45km away from Ballywire, respectively).

These historic Cu-Ag occurrences can be interpreted as the eroded remnants of originally more vertically extensive mineralizing systems, likely representing the roots of stratigraphically higher Zn-Pb-Ag mineralization. At Ballywire, the mineralizing system has the potential to be much larger than its neighbouring occurrences (based on a relatively larger footprint to date); additionally, any Cu-Ag mineralization would notionally be intact below the existing Zn-Pb-Ag mineralization.

Given the compelling nature of this exploration model, Group Eleven added a third rig and began drilling this deeper Cu-Ag target this week.

Notes to Exhibit 8: (a) Pallas Green MRE is owned by Glencore (see Glencore's Resources and Reserves Report dated December 31, 2024); (b) Stonepark MRE: see the 'NI 43-101 Independent Report on the Zinc-Lead Exploration Project at Stonepark, County Limerick, Ireland', by Gordon, Kelly and van Lente, with an effective date of April 26, 2018, as found on SEDAR; and (c) the historic estimate at Denison was reported by Westland Exploration Limited in 'Report on Prospecting Licence 464' by Dermot Hughes dated May, 1988; the historic estimate at Gortdrum was reported in 'The Geology and Genesis of the Gortdrum Cu-Ag-Hg Orebody' by G.M. Steed dated 1986; and the historic estimate at Tullacondra was first reported by Munster Base Metals Ltd in 'Report on Mallow Property' by David Wilbur, dated December 1973; and later summarized in 'Cu-Ag Mineralization at Tullacondra, Mallow, Co. Cork' by Wilbur and Carter in 1986; the above three historic estimates have not been verified as current mineral resources; none of the key assumptions, parameters and methods used to prepare the historic estimates were reported and no resource categories were used; significant data compilation, re-drilling and data verification may be required by a Qualified Person before the historic estimates can be verified and upgraded to be compliant with current NI 43-101 standards; a Qualified Person has not done sufficient work to classify them as a current mineral resource and the Company is not treating the historic estimates as current mineral resources. 'Rathdowney Trend' is the south-westerly projection of the Rathdowney Trend, hosting the historic Lisheen and Galmoy mines.
