Lodestar identifies five targets at Goldrun

Mr. Lowell Kamin reports LODESTAR METALS PROVIDES EXPLORATION UPDATE ON GOLDRUN PROJECT IN NEVADA: FIVE NEW UNDRILLED IP TARGETS SUPPORTED BY SIGNIFICANT GOLD INTERSECTIONS AND HIGH-GRADE SILVER Lodestar Metals Corp. has identified five new undrilled, high-priority induced polarization targets at its flagship Goldrun project. These targets, defined through the 3-D integration of historical deep dipole induced polarization data with drill results and surface sampling, are supported by strong gold intercepts and exceptional silver grades, and demonstrate clear-scale potential for mineralization. The company has launched a multilayered exploration program -- including a 395-sample soil geochemistry survey, a high-resolution ground magnetic survey scheduled for September and newly processed lidar mapping -- to further refine these targets and advance toward potential discovery. Lowell Kamin, president and chief executive officer of Lodestar, stated: "At Lodestar, our focus is simple: find high-impact discoveries in the best places to explore. Our work at Goldrun is progressing steadily, driven by strong data and smart use of capital. We believe we're on the path to uncovering new gold and silver systems in Nevada, and we're committed to delivering long-term value for our shareholders." Technical director Leo Horn commented: "Our latest compilation work integrating historical DDIP data into 3-D has provided several breakthrough targets where strong chargeability IP anomalies are likely to represent disseminated sulphide mineralization commonly associated with gold and silver deposits. Significant nearby gold intersections, along with exceptional silver results -- including over 100 g/t Ag in drilling and up to 3,307 g/t Ag in surface samples -- greatly enhance the prospectivity of these exciting new drill targets. Together, these results further demonstrate the scale potential of mineralization at Goldrun." DDIP review and 3-D targeting advancements As previously mentioned, the company has integrated historical DDIP data into the geoscience analyst 3-D software with the support of geophysical consultant Resource Potentials. Following an initial review, five promising IP targets (T1 to T5) have been identified from five interpreted DDIP cross-sections across two highly prospective areas: Gomes and Independence. Highlight results include the following. (1) Gomes prospect: Two undrilled chargeability anomalies are located 140 metres apart between significant historical intersections of gold and silver with the standout intersections: GAD-4: which contains a gold-rich zone of 13.7 metres at 1.3 grams per tonne gold including 1.5 m at 5.1 g/t Au as well as a silver-rich zone of 19.8 m at 26 g/t Ag and 0.3 g/t Au including three m at greater than 100 g/t Ag and 1.2 g/t Au; and GAD-2: 18.3 m at 0.8 g/t Au from 55 m and 33.5 m at 0.4 g/t Au from 179.8 m. (2) Independence trend: Three undrilled chargeability anomalies are observed along the eastern Independence trend over a 650-metre strike, which are strongly supported by historical intersections, including: HH-22: 10.7 metres at 55 parts per million Ag and 0.36 g/t Au from 47.2 m including 1.5 m at 218 g/t Ag and 1.2 g/t Au; UC-01: 15.5 metres at 38 g/t Ag and 0.35 g/t Au was reported from 18 metres. These gold targets are significantly enhanced by high-grade silver at surface, where recent 2024 rock sampling, as derived from the National Instrument 43-101-compliant study (see National Instrument 43-101 technical report on the Goldrun property, May 12), returned up to 3,307 g/t silver and 2.4 g/t gold. The sampling was conducted by Lodestar and Axiom consultants. This work has clearly highlighted at least five high-priority drill targets for gold mineralization as well as high-grade silver where consistency of the anomalies over considerable strike length of at least 140-plus metres at Gomes and 650-plus metres at Independence, which strongly supports scale potential of these prospect areas. Soil survey completed in southern Goldrun The company has elected to focus its 2025 soil geochemistry program on the southern half of the Goldrun claims. This area hosts the majority of historical drilling, known mineralization and geophysical coverage to date: A total of 395 soil samples were collected by Rangefront Geological Services. Sampling was completed on a 100-metre-by-100-metre grid, with 50-metre-by-50-metre spacing in areas of known mineralization. Samples have arrived at ALS and will be subject to fine fraction sieve followed by low level gold and full suite multielement analysis through aqua-regia digest. The soil analysis will significantly enhance drill targeting accuracy and help define the deposit style. This is crucial given the known presence of multiple deposit styles on the project, including carbonate replacement, Carlin-style, epithermal and other intrusive-related styles. Magnetics and lidar -- enhanced structural targeting tools The company has secured a cost-effective, high-resolution ground magnetic survey covering the entirety of the Goldrun claims. The survey, to be conducted on 25-metre-spaced lines, will be carried out by Zonge International. Scheduled for September, 2025, the survey is designed to significantly enhance the identification of key gold-silver-bearing structures in conjunction with the property's soil geochemistry. This will aid in defining potential drill targets that have not yet been identified through the reinterpreted induced polarization geophysics. Furthermore, the survey will complement the recent acquisition of high-resolution lidar digital elevation model data and imagery, which provide valuable insights for structural analysis across the property. There is a notable correlation between the lidar data and the historical structural interpretation made by Cambior in 1997, reinforcing the potential for further exploration and discovery.
