WINSHEAR REPORTS ADDITIONAL SOIL SAMPLING RESULTS, PRESENTING NUMEROUS LARGE GOLD TARGETS FROM THE 2025 EXPLORATION PROGRAM AT THE THUNDER BAY PROJECT

Winshear Metals Corp. has released results from the 2025 follow-up soil sampling program over the 360-square-kilometre Thunder Bay project in Ontario, which has identified several large gold targets.

Richard Williams, chief executive officer of Winshear, commented: "We are very happy with the results from the 2025 exploration program, which demonstrate the potential for large-scale gold systems on the property. The locations of these targets, centred around major structural intersections, is very encouraging."

Summary

• A total of 272 reconnaissance till samples were collected.
• Till sample results clearly identified the Inflection and El Dorado targets as well as a number of secondary targets in the central and northern parts of the project area. All till samples were analyzed for multielement using aqua regia digestion and inductively coupled plasma mass spectrometry with an optical emission spectroscopy (ICP-OES) finish and fire assay with an atomic absorption finish (FA AA) for gold, with initial results reported September, 2025 (see news release dated Sept. 22, 2025).
• A total of 565 B horizon soil samples were subsequently collected in more detailed sampling density over the Inflection and El Dorado targets in Q3/Q4 2025. These were analyzed with the same analytical package as the till samples.
• Soil sample results clearly show large gold-in-soil anomalies at both Inflection and El Dorado.
• The Inflection gold target is focused in a structurally complex area at the intersection of the southeast-trending Shebandowan and Gold Hill faults, and the northeast-trending Loon Lake and Thunder Bay faults.
• The El Dorado target is located at the intersection of the Loon Lake/Thunder Bay faults with the east-west-trending El Dorado fault. This target is open in all directions.
• Subsequent to the 2025 field season, the company decided to reanalyze all till and soil samples for gold using Instrumental Neutron Activation Analysis (INAA) to exploit this technique's lower detection limit. While there was some discrepancy between the FA AA and INAA analytical techniques, the results largely correlate spatially, apart from a third strong anomaly identified in MacGregor township in the INAA results.
• The approximately 10-kilometre-long anomaly, named the MacGregor target is located between the Inflection and El Dorado targets, where the MacGregor fault intersects the Loon Lake fault (120 parts per billion Au in till).
• Finally, a secondary and intriguing target named Kingfisher, was located along the Kingfisher fault in the northern part of the project area. The company has expanded its land potion to cover more of this prospective fault.
• INAA gold results for the soil samples clearly show the strength of the Inflection target, with assays up to 299 ppb Au.

2026 work program

The company will conduct a number of detailed infill soil sampling grids as soon as weather conditions permit, followed by airborne magnetics to refine the gold targets for prospecting and drill target definition.

Technical information

Till samples were collected by using pickaxes and shovels to excavate a hole deep enough to expose unweathered material and determine if it was basal till before an approximately three-kilogram sample was collected. Samples were stored at the contractor's secure warehouse facility before being transported by the contractor staff to the Actlabs laboratoy in Ancaster, Ont.

B horizon soil samples were collected at individual stations using a hand auger. At each site, surface organic material (O/A horizons) was removed. Where present, a B-horizon soil sample was collected from the first well-developed, oxidized horizon beneath the organics (typically approximately 15 to 40 centimetres depth, depending on local conditions). Approximately 0.5 kg of fine material (avoiding large clasts, roots and obvious contamination) was placed into labelled sample bags and sealed.

Sample ID, UTM co-ordinates (NAD83 Zone 16), sample medium/type and site notes were recorded in the field. Samples were transported to Activation Laboratories Ltd. (Actlabs) in Thunder Bay, Ont., for preparation. Gold was analyzed using a 30 g sample and FA AA (fire assay with an atomic absorption finish) with a detection limit of five ppp. Multielement analysis was conducted using Actlabs' 1E3 method -- ICP-OES (inductively couple plasma optical emission spectroscopy finish), providing results for 38 elements, including silver, arsenic, cobalt, copper, molybdenum, nickel, lead, antimony and zinc.

Instrumental Neutron Activation Analysis (INAA) analysis was also conducted by Actlabs. Samples are encapsulated and irradiated in a nuclear reactor. After a suitable decay, samples are measured for the emitted gamma ray fingerprint. INAA is considered to be a very good technique for Au analysis with a detection limit of one ppb.
