WALKER LANE RESOURCES LTD. RECEIVES POSITIVE RESULTS FROM AIRBORNE GEOPHYSICAL SURVEYS AND GEOLOGICAL MAPPING COMPLETED BY COEUR ON THE SILVERKNIFE PROPERTY, BC AND ALSO ARE CLARIFYING DETAILS RELATED TO THEIR RECENT NEVADA TRANSACTIONS

Walker Lane Resources Ltd. has received results from Coeur Silvertip Holdings Ltd. on field geophysical and geological studies completed in late 2024 on the Silverknife property in British Columbia. Coeur contracted Expert Geophysics Ltd. and Precision Geophysics to complete the airborne geophysical surveys and 39627 Yukon Inc. to complete geological mapping of the Silverknife property and an initial geochemical survey of the northern portion of the property.

This work was completed by Coeur as a part of the option agreement for the Silverknife property with Walker Lane. The four-year option agreement provides for $3.55-million in work expenditures and $500,000 in property payments by Coeur to earn a 75-per-cent interest in the Silverknife property, which is immediately adjacent to Coeur's Silvertip mine claims.

The primary results of these work efforts are:

• The geological map of the property is now significantly revised and better defines the location of prospective lithological units;
• The geophysical surveys served to:
  • Define the presence of complex fault structures;
  • Present additional conductivity data;
  • Identify a potential new prospective zone in the northeastern section of the property;
  • Enhance the continued prospectivity of the Tootsee River North, Silverknife Central and Silverknife South zones of exploration prospectivity.

Kevin Brewer, president and chief executive officer of Walker Lane noted, "We are very pleased with that the geological mapping and airborne geophysics has clearly served to better define and confirm the zones of exploration prospectivity. This work identified key structural features such as faults, which are known in the region to be controls and loci of mineralization. Other features such the presence of fugitive calcite in outcrops typically demonstrates that you are in close proximity to a potential carbonate replacement deposit (CRD). The four prospective areas on the Silverknife property are both significant and of substantial areal extent and present valid drill targets for future exploration efforts. The property has been subjected to limited drilling confined primarily to the Silverknife prospect that in itself remains open for further expansion along strike and at depth. Given the propensity of potential mineralization in such close proximity to the Silvertip deposit, one of the world's largest and highest-grade CRD deposits, finding this much prospectivity is a very exciting development. There clearly is a great amount of work to be completed at Silverknife. We look forward to Coeur's continued commitment to explore Silverknife, which may include some drilling."

Precision Geophysics -- airborne high-resolution gradient magnetic and radiometric survey results

When magnetic and radiometric data are integrated into a single-pass airborne geophysical survey, they provide complementary information that serves as a robust geophysical framework. The magnetic and radiometric data collected by Precision were useful in mapping lithology, structure and alteration features present on the Silverknife property. The total magnetic intensity (TMI) data indicated the potential existence of three main lineaments within the Silverknife property. In the instance of Silverknife, the lineaments express underlying geological structures such as faults. Faults are important as they present corridors for the migration of mineralizing fluids. Two lineaments, northeasterly and northwesterly trending are prominent throughout the property area. The third lineament is a more northerly feature that occurs in the area of the Silverknife property. The most prominent structural feature identified from the TMI data was a northeasterly trending structure known as the SVT NE fault, which is a major regional fault that transects the central portion of the Silverknife property. In this area, the SVT NE fault and the secondary lineaments appear to be in a crosscutting relationship, which are often prime target areas for mineralization and are considered highly prospective as they coincide with historical soil geochemical anomalies in the Silverknife Central zone. Geological mapping has also indicated the presence of Atan and Kechika group limestones in this area, which are favourable rock units to host carbonate replacement deposits. The Silvertip mine is characterized as a carbonate replacement deposit. In addition, the potential of additional structures throughout the Silverknife Central zone to the western boundary of the Silverknife claims presents numerous targets for drilling and expansion of mineralization identified in the Silverknife property, and this area is yet to be drilled.

The Precision TMI data also indicated a near-north-trending fault that cuts the McDame limestones and Tapioca group in the Silverknife South zone. The TMI data were complemented by residual magnetic intensity (RMI) and reduced to magnetic pole (RTP) that also showed the same structural lineaments.

In-line gradient (ILG) and horizontal gradient showed the same structure features as the TMI data.

However, they also showed the potential for more complex faulting along the southern and northern contacts of the Cassiar batholith that could represent block faulting in the metasediments.

In addition, these data showed the presence of a north-oriented structure in the northeasternmost portion of the Silverknife property, which presented a new area of exploration prospectivity previously undetected.

Calculated vertical gradient (CVG) data presented a distinct continuum of structures extending from south of the Silverknife property into the Silverknife South zone.

The radiometric data serve to delineate the extent and potential contacts of different lithological rock units. Areas of high potassium were noted to occur in the Tootsee River North and Northeastern zones. The significance of these data is not yet determined.

Expert Geophysics helicopter-borne electromagnetic and magnetic survey results

Electromagnetic and magnetic surveys were carried out to:

• Provide data to aid in mapping bedrock structures and lithologies, including possible alteration and mineralization zones;
• Provide observations of apparent conductivity corresponding to different frequencies;
• Inverting EM (electromagnetic) data to obtain the distribution of resistivity with depth;
• Collecting VLF-EM (very-low-frequency electromagnetic) and magnetic data to study properties of the bedrock units.

The electromagnetic survey verified information from the data in Precision's surveys but also identified new information. A conductivity low south-southeast of the Silverknife property suggests the presence of a near-surface intrusive in that area. This is important because an intrusive provides a potential heat source and driver for mineralizing fluids into the overlying sediments, which comprise limestones and sandstone, which are good hosts for CRD mineralization. The survey also indicated a conductivity high in the northeastern zone further strengthening exploration interest in that area.

Several axes of high-conductivity/low-resistivity were found to transect the Silverknife property and are coincident with interpreted fault structures. This relationship is important as mineralization within the Rancheria silver district is often associated with faults and may also be correlated with the axes of a conductivity anomaly.

Three conductive axes occur in the: (i) Tootsee River North zone; (ii) the Silverknife Central zone; and (iii) coincident with the regional SVT NE fault structure that transects the central portion of the property. This last axis extends from outside of the Silverknife claim block and thence east-northeasterly across the entire claim block. This therefore represents the potential for a major fault structure with the geophysical signatures of silver-rich CRD being that of high conductivity and low resistivity. Additional resistivity data enabled the development of a three-dimensional lithographic model suggesting the orientation and extent of the rock units within the Silverknife property. This information is expected to significantly aid the planning of future drill programs.

VLF-EM data served to further verify other data sets as to the possible extent and location of fault structures within the Silverknife property.

Geological mapping

An updated geological map has been constructed from field mapping, drill data and geophysical surveys. The extent of prospective units to host CRD mineralization has been found to be considerable. More specifically, the highly prospective McDame limestone occurs in both the Tootsee River North zone and the Silverknife South zone. Other prospective units in the central part of the property, including the Atan and Kechika group limestones, occur within the central portion of the property, which is now assumed to be of significant prospectivity from previous known CRD mineralization and positive geochemical and geophysical signatures.

Summary

This recent geophysical work, in combination with property mapping and previous geophysical data, has contributed significantly to the understanding of the geology of the Silverknife property. It has also contributed significantly to better defining targets for CRD mineralization and assisting to pinpoint targets for extensive drill campaigns.
