Talon Metals Corp. (TSX: T.TLO, Stock Forum) said it has received positive metallurgical results from its Trairão project in Brazil.
The Trairão Iron project, located in Pará State, has a 1.4 billion tonne indicated mineral resource estimate plus a 1.2 billion tonne inferred mineral resource estimate.
According to the Talon Metals press release, previously tested samples, using Davis Tube at P100 passing 45 microns, were selected for further Davis Tube testing at a finer grind of 25 microns.
The updated metallurgical test results from these samples confirm that in the vast majority of cases, the concentrate grades increase significantly with finer grinding, indicating that a premium grade product can be attained from the Trairão Project.
Thirty samples of magnetite-rich mineralization were submitted to SGS in Lakefield, Ontario for Davis Tube testing at a grind P100 of 25 microns using low magnetic intensity separation of 800 Gauss to produce a iron concentrate.
Concentrate grades increased significantly with finer grinding, with grades ranging between 58.9% and 71.3% iron, with the average iron grade increasing from 60.1% to 67.1%.
Due to the requirement for finer grinding of the fresh rock, Talon has identified a number of energy efficient, proven, large scale fine grinding technologies capable of handling high rock volumes.
To this end, Xstrata Technology, who is independent of Talon, has engaged with Talon to assess the applicability of its IsaMill™ Technology on the Trairão Project.
The IsaMill™ Technology is an energy efficient, large scale grinding machine, which, if applicable to the Trairão Project, would allow for large scale, economically efficient fine grinding at the Trairão Project in order to maximize liberation while controlling energy consumption.
Talon is an exploration and development company focused on its iron projects in Brazil.
On Thursday, Talon’s stock was up 8.7% and was trading at $0.25 a share. The company has a market cap of $23 million, based on 92 million shares outstanding. The 52-week high and low was $0.85 and $0.23 respectively.
