At the time, the company was still relying on standard industry250.847.9301methods to estimate the gold grade.info@hy-techdrilling.comWe did our first bulk sample, Whymark recalls, but before we extracted it from the ground, we drilled it off with a standard diamond drill core to try to predict what the grade would be.The results were something of ashock, returning a very different grade from the mill than from what Inventus had drilled. The mismatch, it was deduced, pointed to a strong nugget effect, resulting from gold being distributed unevenly and as clusters, thereby making conventionaldrilling less reliable. This triggered the need to extract larger, more representative samples.Pivoting to bulk sampling required several years of permitting and environmental work. And since the company was limited to 1,000 tonnes under standard exploration rules, Inventus was obliged to pursue more ONTARIO PROSPECTOR WINTER 2025/26 11'
