Premier1 Concludes Extensive Drilling Program at Yalgoo Gold Project in Western Australia
Perth-based exploration company Premier1 has successfully completed a reverse circulation (RC) drilling campaign at its Yalgoo gold project located in Western Australia. This initiative aimed to test a series of high-priority targets as the company seeks to expand its presence within the prospective greenstone belt region.
The drilling program involved 16 RC holes, totaling an impressive 2776 metres. The focus was on structural and geochemical sweet spots across the large-scale hydrothermal system at the company's Mt Kersey, Central Block, Carlisle, and Crescent South prospects. Funding for this effort was partially supported by a grant from Western Australia's highly competitive Exploration Incentive Scheme.
Focus on Mt Kersey Prospect and Key Targets
The primary target of the drilling was the Mt Kersey prospect, situated near Premier1's Wadgingarra maiden inferred resource, which currently holds 150,000 tonnes grading 2.7 grams per tonne (g/t) gold for 13,000 ounces. Nine RC holes, amounting to 1924 metres, were drilled to test a 500-metre-long structural and geochemical trend associated with a major interpreted inverse fault, often crucial for gold transport.
Soil geochemistry in the area has revealed a broad hydrothermal footprint with a gold anomaly stretching north-south. This includes pathfinder zoning, transitioning from deeper molybdenum in the south through bismuth-tellurium and tungsten zones to shallower arsenic-dominant sections in the north. Historical rock chips from the anomaly zone have returned exceptional grades, such as 26.4g/t and 14.2g/t gold, highlighting its potential.
Elsewhere, Premier1 drilled three holes at the Central Block prospect, targeting previously untested electromagnetic anomalies and historical surficial gold workings. Another three holes tested the Carlisle prospect, following up on a previous intersection of 10 metres grading 3.1g/t gold from 19 metres, including 7 metres at 4.3g/t. The final hole was drilled at Crescent South, aiming to extend a high-grade intercept from last year's drilling that returned 3 metres at 31.5g/t gold from 97 metres, with one metre at 91.9g/t gold.
Geological Context and Historical Significance
The Yalgoo project is located in the Yalgoo-Singleton greenstone belt, positioned between major producers Ramelius Resources to the north and Capricorn Metals to the south. This area, founded in the 1890s during a gold rush, is known for hosting high-grade orogenic gold and base metals deposits. It lies along strike from operations like 29Metals' Golden Grove and newer discoveries such as Capricorn Resources' Golden Range and Deflector mine, with historical significance for gemstones like emeralds and topaz.
Premier1's Wadgingarra prospect serves as the anchor for the Yalgoo holding, featuring a 13,000-ounce near-surface resource where high-grade gold starts at surface and remains open along strike and at depth. Despite limited modern drilling, early 2025 RC work yielded strong results, including bonanza hits at Crescent Carlisle prospects.
Company Statements and Future Outlook
Simon Phillips, executive director of Premier1, stated, "Getting the rig on the ground and completing drilling at Mt Kersey is a milestone for the company, especially following our recent 100% acquisition of the Yalgoo gold project." Exploration manager Paul Smith added, "The EIS-funded program successfully intersected the key geological units and structures, including metasedimentary units and quartz dolerites. We are encouraged by initial observations from drill chips and logging."
Samples from the drilling campaign have been sent to the laboratory for assays, with results expected within four to six weeks. These outcomes could reveal whether Premier1 is sitting on a broader gold system beneath the Yalgoo greenstones, potentially enhancing the company's resources and balance sheet.
Beyond Yalgoo, Premier1 is not limited to a single project. Its second major venture, Abbotts North, is located in the active Meekathara-Murchison greenstone belt, further diversifying its exploration portfolio. If assay results align with recent drilling successes, Premier1's expanding resources may significantly boost the region's gold prospects and the company's financial standing.
