Data Description

NGEx Minerals has compiled a collection of digital data and files that relate to drilling and exploration at its Lunahuasi Project, Argentina, including collar coordinates, composited assay intervals, and down-hole survey data (“The Dataset”), that are available for download at https://ngexminerals.com/projects/vicuna-district/lunahuasi/lunahuasi-overview/

The Dataset includes all drilling assay and bulk density results on a sample-by-sample basis, previously disclosed as summaries or composite intervals within NGEx Minerals news releases.

While NGEx Minerals has made best efforts to validate and verify the data using the methods described below, the accuracy, completeness, or reliability of The Dataset cannot be guaranteed. Users are advised to exercise caution and discretion in relying on the information contained in The Dataset for any purpose.

Qualified Person Statement

The information within The Dataset has been verified for NGEx Minerals (2023-2025) era data, includes some historical data that has not been possible to fully verify, and was compiled under the supervision of Bob Carmichael, B.A.Sc., P.Eng., Vice President Exploration for NGEx Minerals, a ‘Qualified Person’ as defined under Canadian National Instrument 43-101.

Samples were cut at NGEx’s operations base in San Juan, Argentina by Company personnel. Diamond drill core was sawed and then sampled in maximum 2-meter intervals, stopping at geological boundaries. Core diameter is a mix of PQ, HQ and NQ depending on the depth of the drill hole. Samples were bagged, tagged, and packaged for shipment by truck to the ALS preparation laboratory in Mendoza, Argentina where they were crushed and a 500g split was pulverized to 85% passing 200 mesh. The prepared sample splits were sent to the ALS assay laboratory in Lima, Peru for copper, gold and silver assays, and multi-element ICP. ALS is an accredited laboratory which is independent of the Company. Gold assays were by fire assay fusion with AAS finish on a 30g sample (Au-AA23). Any samples returning > 10 g/t were then reanalyzed by fire assay with gravimetric finish on a 30g sample (Au-GRA21). Copper and silver were assayed by atomic absorption following a 4-acid digestion. Samples were also analyzed for a suite of 48 elements with ME-MS61 plus mercury and a sequential copper leach analysis was completed on each sample with copper greater than 500ppm (0.05%). Sequential copper analysis involves the sequential leaching of the sample by acid, followed by a cyanide solution. It can be used to differentiate copper speciation, with copper oxide minerals leachable with acid and secondary copper minerals (enargite, chalcocite, covellite) leachable by cyanide. The residual copper remaining following the sequential leaches it typically contained in chalcopyrite and bornite. Copper and gold standards as well as blanks and duplicates (field, preparation, and analysis) were randomly inserted into the sampling sequence for Quality Control. On average, 10% of the submitted samples are Quality Control samples. No data quality problems were indicated by the QA/QC program.
