Summary Points:
- Lefroy Exploration (ASX:LEX) has increased its near-surface gold resource at Mt. Martin by 13% to 439,000 ounces.
- The update follows 30 drill holes, with assays revealing significant gold intercepts, including 21.2m @ 4.32g/t gold and 33m @ 3.82g/t gold.
- Exploration efforts continue at Mt. Martin and the broader Lefroy Gold Project, targeting multiple shear zones for further resource growth.
Lefroy Exploration (ASX:LEX) has recently reported a 13% increase in its near-surface gold resource at the Mt. Martin deposit, now reaching 439,000 ounces. This boost in resource is based on the results from a new set of 30 drill holes that focused on zones located less than 200 meters deep. These efforts have strengthened the company's position in the Kalgoorlie region of Western Australia, where the Lefroy Gold Project (LGP) spans 635 square kilometers.
Key Drilling Results
The latest drilling campaign targeted the main shear zone, as well as the 'east shear,' both located within the Mt. Martin area. Notable assay results included:
- 21.2 meters @ 4.32g/t gold from 30 meters depth
- 33 meters @ 3.82g/t gold from surface within the main shear zone
- 3.7 meters @ 3.98g/t gold from 38 meters depth
- 35 meters @ 1.8g/t gold from 209 meters depth
These significant intercepts demonstrate the high-grade potential of Mt. Martin, particularly in shallow areas, and emphasize the value of further exploration within this deposit. Additionally, the recent drilling results contribute to the overall growth of the gold resource, especially in the inferred category.
Exploration and Growth Prospects
Lefroy Exploration's 100% ownership of the Mt. Martin deposit allows it to pursue aggressive exploration and resource development strategies. Geotechnical teams have identified multiple shear zones within the project area, focusing particularly on the Main, East, and Adelaide Shear target areas. These corridors are expected to yield further growth in the gold resource as exploration continues.
The Mt. Martin deposit forms a critical part of the broader Lefroy Gold Project (LGP), located in the well-established Kalgoorlie terrane. This area is known for its mining infrastructure, making it a favorable location for future mining operations. The company has also utilized geophysical surveys, including geomagnetic and downhole analysis, to refine its resource estimates and target new zones of interest.
Strategic Direction
Lefroy Exploration’s leadership has expressed optimism regarding the potential for further growth at Mt. Martin. According to CEO Graeme Gribbin, the company is highly encouraged by the recent expansion of the near-surface gold resource. The next phase of exploration will involve deeper drilling programs, targeting down-plunge extensions of the Main, East, and Adelaide Shears, which could further increase the resource base.
In addition to Mt. Martin, the company’s broader Lefroy Gold Project continues to show promise, particularly with the high-grade potential identified at the Burns Central Au deposit. This strategic focus on shallow, high-grade deposits positions Lefroy Exploration well for future development and resource expansion across the project area.
Bottomline
Lefroy Exploration's continued success at Mt. Martin highlights the potential for significant resource growth within the Lefroy Gold Project. With ongoing exploration targeting multiple high-priority shear zones and additional geotechnical work underway, the company is well-positioned to unlock further value in the Kalgoorlie region. The 13% increase in near-surface gold resources strengthens Lefroy's future development prospects, particularly as it focuses on advancing its exploration programs across its extensive landholding in Western Australia.
