Outback Goldfields has provided an aerial drilling program update at the Yeungroon Gold Project in central Victoria, Australia. The purpose of the large-scale drilling on top of the shale was to widen and sample new rock below a wide, open, two-mile-long anomaly at the surface.
HIGHLIGHTS: Extensive Co. Gold Arsenic Anomaly in Two-Mile Rock Samples: Geophysical directional drilling at O’Connors revealed large areas of highly anomalous arsenic and gold, similar to those observed in the nearby alteration halos of other gold-quartz reefs in the center of the country. Victoria. Extensive drilling over the shale was the first effective step: shallow grid-based drilling through several blind and hidden geophysical targets proved to be an important and cost-effective first step in generating new drilling targets. Anomalies open along the extension: Encouraging gold results at the northern and southern ends of the anomalies support the possibility of further expansions along the line.
The company is very pleased with O’Connors’ discovery campaign and results. The large-scale aerial drilling program is designed to explore beneath the vegetation and take samples from the top of the bedrock below the cap. These analyzes represent only 60% of the total meters drilled, so additional analyzes for gold from other wells are warranted.
The program succeeded in identifying a new large area of gold anomaly associated with a large-scale open basis anomaly. The spatially synchronized gold and arsenic anomalies are associated with the north-northeast running O’Connors fault and related fission faults. The Geological Survey of Victoria published a 2008 study of the geochemistry of host rocks and alteration halos around gold deposits in central Victoria.
The study found that low-grade gold halos can extend 30–90 m from primary mineral structures (such as quartz reefs) with threshold values between 10 ppb and 100 ppb gold (Arne et al., 2008). Higher gold values for the O’Connors drilling program with air drilling of 0.43 g/t (432 ppb) Au and 0.27 g/t (270 ppb) Au (Figs 1 and 2) are highly abnormal and directly represent the objectives of systematic testing. . The O’Connors’ Golden Arsenic Anomaly stretches for more than two miles and remains open the entire length.
This included rock samples, color, quartz veins, and mineral notes, and were made concurrently with the sampling. All samples were transported by Outback from the dig site to the company’s research office in Ballarat.
