Kaiser Reef takes off with drones in Victorian gold search

Junior gold explorer Kaiser Reef has recently completed an underground drone stope survey, using cutting-edge technology to gather data from historical unsurveyed stopes that need to be accounted for in resource and mine studies at the company’s Maldon gold project in the Victorian Goldfields. The research is expected to assist independent consultancy MiningOne in its ongoing resource modelling.

A diamond rig was also recently mobilised by the company from Maldon to its nearby A1 gold mine.

Kaiser contracted underground drone surveying specialists MINELiDAR to conduct the survey using its Emesent Hovermap light detecting and ranging, or “LiDAR” drone mounted technique.

The drone survey is a safe and fast way to survey stopes, drives and shafts especially in situations where the ground cannot be tested for structural stability by engineers.

Data from the survey in conjunction with diamond drillhole results will allow a full resource and future mine plan model to be constructed.

The diamond rig wrapped up the first phase of drilling at Maldon recently and the company will use those findings within specified target regions for resource estimation. Deeper holes were also drilled outside the current model extents that are still awaiting results.

Maldon sits in the heart of the Victorian Goldfields and has produced more than 1.74 million ounces of gold at a whopping head grade of 28 grams per tonne gold. It is also home to the legendary Nuggety Reef, one of Australia’s highest grade historic gold mines that yielded 301,000 ounces at a startling grade of 187 g/t gold.

The Maldon goldfield is also in the Bendigo zone, with turbidite sandstone, siltstone and shale rock sequences.

Kaiser says one of its key attributes is the extensive existing infrastructure and the close proximity to Kaiser’s gold processing plant, a mere 3km away. The company believes because of the infrastructure a rapid and low-cost development could progress using Kaiser’s existing mining fleet for minimal additional cost.

Some of the historical drill hits that warrant further follow-up drilling work include 0.9m at 103 g/t gold, 2.73m grading 42.2 g/t gold, 2.75m going 22.6 g/t gold and a 0.44m hit that gave up a whopping 205 g/t gold.

Kaiser believes Maldon has a distinct advantage as it houses an established and serviced decline that allows excellent underground access for drilling the high-grade lodes and could potentially facilitate the resumption of modern mining in a cost-effective way.

Resource modelling work is steaming along at a historic mine that once produced mouth-watering grades and Kaiser will be eager to see if it can jump-start new life into the mine.
