Highlights
Lighthorse prospect shows extended primary gold mineralisation.
RC drilling confirms continuity of gold-bearing zones.
Mineralisation remains open to the north with further potential.
Kalgoorlie Gold Mining (ASX:KAL) has expanded gold mineralisation at its Lighthorse prospect, with RC drilling revealing significant continuity and depth potential. Exploration continues in multiple areas.
Expanding Gold Horizons at Lighthorse
Kalgoorlie Gold Mining (ASX:KAL) has reported a major advancement in its exploration activities at the Lighthorse prospect, part of the broader ASX mining stocks landscape. The company’s latest reverse circulation (RC) drilling program has revealed a significant extension of primary gold mineralisation, confirming a near-surface anomaly first identified through earlier aircore drilling.
The updated results suggest that the mineralised system remains open to the north, where geophysical surveys have indicated further gold potential. This discovery enhances Kalgoorlie Gold Mining’s exploration footprint and reinforces the prospect’s relevance in the east Kalgoorlie region.
Key Findings from the RC Drilling Program
The second RC drilling campaign at Lighthorse aimed to investigate sub-audio magnetic geophysical targets and follow up on previous aircore anomalies. A total of 38 holes were completed, covering an extensive area and intersecting fresh rock zones rich in primary orogenic gold. These intersections were associated with shearing, alteration, sulphide development, and quartz veining, which provide key structural indicators of gold mineralisation.
Drilling results show continuous gold-bearing intervals, highlighting the potential scale and continuity of the mineralised system. The extended strike length of mineralisation now exceeds earlier estimates, demonstrating the effectiveness of the company’s strategic exploration approach.
Strong Geophysical Correlations Support Exploration
The Lighthorse prospect’s gold mineralisation exhibits a strong correlation with a north-south trending magnetometric conductivity ridge identified during recent surveys. Areas of thick and continuous mineralisation coincide with regions of elevated conductivity and subdued magnetic response. The conductivity ridge extends beyond the limits of current drilling, indicating additional exploration opportunities along strike.
Future RC drilling programs are planned to deepen current holes and better define the geometry, continuity, and depth of primary gold mineralisation. These efforts aim to provide a more comprehensive understanding of the system’s potential below the near-surface depletion zones.
Southern Exploration and Additional Prospects
RC drilling at the southern extent of Lighthorse intersected sub-grade and discontinuous gold anomalies, marking the approximate southern limit of contiguous mineralisation. Further exploration at nearby Wessex and Providence South prospects is ongoing, following up on earlier aircore results.
At Providence South, primary gold intercepts were noted near ultramafic units hosting regional gold deposits. However, deeper drilling at Wessex has yet to confirm significant primary gold, emphasizing the importance of continued exploration and diamond drilling programs to refine understanding of these areas.
Diamond Drilling Progress and Incentive Schemes
Diamond drilling is underway at key targets such as Kirgella Gift and Providence, with drill core currently being logged and processed. Initial samples have been submitted for assay, and results will guide the next stage of exploration and evaluation.
The company has received an initial refund under the Exploration Incentive Scheme following submission of its interim report. This support aids in advancing exploration programs and highlights the government’s backing of mineral exploration initiatives.
Future Plans and Market Implications
Kalgoorlie Gold Mining continues to evaluate the Lighthorse prospect and surrounding areas with a combination of RC and diamond drilling. The ongoing efforts aim to expand mineralisation understanding, targeting zones that could contribute to larger-scale gold deposits in the region. Investors and stakeholders in the ASX stock market are closely monitoring the progress, considering the impact on regional exploration dynamics and potential for future developments.
Further exploration is also likely to influence related indices such as the ASX100, ASX200, and ASX300, as Kalgoorlie Gold Mining’s discoveries could affect sector-wide sentiment. Additionally, exploration outcomes may have implications for ASX dividend stocks that operate in the mining and resources space.
