GOLD: Inventus likes results of Pardo ore sorting and bulk sampling



ONTARIO – Inventus Mining Corp. of Toronto is mulling over the results of two recent studies from its Pardo paleoplacer gold project near Sudbury. The project is a conglomerate-hosted deposit within rocks 2.4 billion years gold. A similar sedimentary formation hosts the Witwatersrand basin, where many of the world’s most productive gold mines are.

Inventus says that the first ore sorting trial on material from Pardo has been very effective. Simulations suggest that 91% of the contained gold could be sorted into only 35% of the original mass (i.e. 35% mass pull). The average simulated gold grade of the product is 29.37 g/t gold, compared to 11.31 g/t in the feed.

A mini-bulk sample weighing 110.7 kg was taken from Pardo so that processing methods could be evaluated. The sample was treated to grinding and gravity concentration on a shaker table. Approximately 69% of the gold was collected by gravity methods. The balance reported to a tailings concentrate. Inventus plans to optimize gold recovery perhaps with the addition of other processes.
