VANCOUVER, BC, April 29, 2025 /CNW/ - Callinex Mines Inc. (the "Company" or "Callinex") (TSXV: CNX) (OTCQX: CLLXF) is pleased to announce plans to advance the Company's 100% owned Point Leamington Deposit, Newfoundland (the "Project"). This Project hosts a volcanogenic massive sulphide ("VMS") deposit (the "Deposit"), which contains significant gold, copper, zinc and silver mineralization and is open for expansion (Pt. Leamington Deposit 3D View). The Deposit is located within a mineral lease and is accessible by road followed by trails and is approximately 37km from the city of Grand Falls-Windsor and is also 20km from the Newfoundland hydroelectric power grid (Pt. Leamington Project Area Overview). Investors are invited to view a pre-recorded webinar detailing the exploration objectives outlined below by viewing: Callinex 2025 Pt. Leamington Deposit Exploration Overview
Max Porterfield, President & CEO of Callinex Mines stated, "Point Leamington is a large, near surface VMS deposit in the mining friendly province of Newfoundland that has a considerable gold resource in addition to copper, zinc and silver. Given the significant rise in metal prices, in particular gold, the intrinsic value of the Point Leamington deposit has risen dramatically overall and in relation to other deposits Callinex possesses." Mr. Porterfield continued, "Additionally, Callinex has strengthened our team with expertise to maximize value at Point Leamington and other projects within the Company's robust portfolio. We plan to aggressively advance this Project with an exploration campaign to expand the known resource and discover new deposits on the broader land package in tandem with mineralogical and metallurgical test work."

1.
Mineral Resources, which are not Mineral Reserves, do not have demonstrated economic viability.
2.
The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.
3.
The Inferred Mineral Resource in this estimate has a lower level of confidence than that applied to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of the Inferred Mineral Resource could be upgraded to an Indicated Mineral Resource with continued exploration.
4.
The Mineral Resources in this Technical Report were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the CIM Standing Committee on Reserve Definitions and adopted by the CIM Council (2014) and CIM Best Practices Guidelines (2019).
5.
The Mineral Resource Estimate was based on August 2021 consensus economics forecast metal prices of US$1,625/oz gold, US$22/oz silver, US$3.50/lb copper, US$1.20/lb. Zinc.
6.
Additional details of the Mineral Resource Estimate, including the parameters and assumptions, are set forth in the Company's news release dated October 25, 2021.
The Company's exploration portfolio hosts several base and precious metals rich VMS deposits strategically located within known mining districts across Canada. The portfolio provides exposure to underlying metal prices, which in an escalating price environment, can have a significant material impact on the value of each specific deposit. Over the last several years Callinex has quietly continued to work on the Point Leamington Project in preparation to advance it at an optimum time. The strong up-move in gold prices over the last year makes now a great time to renew our focus on this Deposit.
Exploration Opportunities
There is an opportunity to significantly expand a higher-grade zone of the Deposit with additional drilling at depth. The most recent hole drilled in 2004, PL04-077, intersected 4.67m grading 4.37 g/t Au, 15.05% Zn, 57.88 g/t Ag and 0.36% Cu and PL-056 intersected 4.51m grading 2.27 g/t Au, 8.84% Zn, 81.66 g/t Ag and 0.61% Cu, which are the two deepest holes to intersect the Deposit. Drill holes PL04-077 and PL-056 are located 150 metres apart and the Deposit is open for extension below the 435 metre level (Pt. Leamington 3D Long Section).
The Deposit also has potential to host additional tonnage along strike. Drill hole PL04-073, drilled during the 2004 exploration campaign, intersected 3.9m grading 1.65 g/t Au, 5.18% Zn, 33.1 g/t Ag and 0.27% Cu (Pt. Leamington Deposit Long Section). The Company is currently reprocessing historic borehole pulse electromagnetic data surrounding the largely untested area and additional drilling may be completed in the future.
The Point Leamington Deposit style of mineralization, alteration, and host rocks suggests that it is a Kuroko-type VMS deposit hosted in Cambro-Ordovician age rocks, which are similar to the past producing Buchans and Duck Pond Mines in the Point Leamington area. The massive sulphides occur at a transitional period between altered felsic volcanics (dominantly flows, breccias, and pyroclastic) and a sedimentary / mafic volcanic sequence. As a result of reviewing historical regional data, the Company believes that there is significant opportunity to discover additional deposits with further exploration efforts.
Additionally, Callinex's larger exploration land package at the Project includes a number of untested geophysical anomalies within favorable geologic units that will be further refined with plans to be drilled. These target areas have been identified after reviewing Callinex's proprietary exploration database including over 2,400 line-kilometers of modern airborne electromagnetic survey data with a focus on nearby areas with a similar geological setting as the Deposit.
Gold, Copper and Zinc Mineral Processing
Callinex has engaged a leading consulting firm with a core expertise in the economic metallurgical recovery of gold, to oversee and manage metallurgical work at the Deposit moving forward. From a review of prior mineralogical studies and metallurgical test work, a process will be put in place to confirm recovery of copper and zinc as well as a promising processing route has been identified for the recovery of gold from the Deposit.
The Company plans to collect representative samples from both identified gold zones in the Deposit, to be used initially for a detailed mineralogical study. These samples will be used in a bench scale metallurgical test program, involving a flotation program to recover copper and zinc, separate arsenopyrite from pyrite, and to recover liberated gold. The bench scale test work is expected to be confirmed by a test program in a respected commercial lab. Gold concentrate produced will be processed with a focus on leach alternatives to maximize gold recovery or sold in the open market. The results of this multi-phase metallurgical program will be used to generate a preliminary economic evaluation of the entire Project.
The Company also intends to complete an up to 5,000 meter exploration campaign at the Project to grow the high grade mineralization associated with the deposit, test newly identified high priority targets and collect samples to complete mineralogical studies and metallurgical testwork for the economic recovery of the metals with a particular focus on gold.

Point Leamington Project
The Point Leamington Project, consisting of Mining Lease 136 (2655), is located approximately 37km by road and trails from the City of Grand Falls-Windsor and approximately 20km from the provincial power grid. The Deposit is a large, felsic-hosted VMS deposit that dips 70 degrees to the west, has a strike length of 500m and a maximum thickness of 85m. Massive sulphides have been intercepted to a depth of 360m below surface from a total of approximately 21,714m of drilling in 72 drill holes. Regional government mapping and lithogeochemical sampling has indicated that Point Leamington's host volcanic stratigraphy extends well beyond the vicinity of the Deposit.
