Our History
Petra Minerals Pty Ltd was formed to manage and direct the Company's exploration and development of minerals in alluvial form in the Central Victorian Goldfields.
Since 1996 the company has been assessing the deep leads in the Creswick, Clunes, Moolort and Lexton areas. Deep leads are ancient rivers now buried deeply beneath the current land surface. In the late 1800's the deep leads were extensively mined for their alluvial gold. In the Creswick - Clunes areas some
At 1 March 2021 Petra Minerals holds a 100 percent interest in two exploration licences and three retention licences covering an area of approximately 287 square kilometres along the Berry, Ascot-Clunes, Moolort and Madame Hopkins deep leads (see map of Petra's licence holdings below).
Our Resources
Within the sediments of the deep leads Petra have delineated a resource of high purity quartz of the order of 7 billion tonnes which contains yet to be quantified resources of gold and heavy minerals including rutile and zircon.
This represents a very substantial resource.
Analysis of the quartz shows that the raw material in the deep leads is of high purity and is suitable for beneficiation to World Class specifications for the manufacture of ultra pure quartz for use in the semiconductor industry, for solar panels, and TV and monitor screens.
Since 2009 Petra have been researching and developing a propriety bore-hole mining method to extract the alluvials from the deep leads. By this method the resource is able to be extracted through small diameter drill holes without the need for large scale excavation and land-surface disturbance that characterises many mining operations. The borehole mining process uses only the natural water and in-ground pressure that occurs in the deep lead and does not introduce any chemicals into the natural system. The bore-hole mining method does not involve the breaking up of the ground - a process known as "fracking".
Encouraged by the discovery of the resource and by the discovery of a mining method that minimises environmental impacts, Petra have determined to continue studies to take the project from the current exploration operations to detailed resource evaluation, prefeasibility and mining evaluation with the aim of developing a mining operation that is consistent with the expectations of the local community.
This will involve extensive community consultation as detailed environmental effects studies, mining feasibility, product quality and market evaluation are undertaken to establish the viability of a mining operation.
