NewCastle Gold’s preliminary surface drill testing program has been completed over the JSLA backfilled pit at the Castle Mountain gold project located in San Bernardino County, California. This work is part of an initial assessment of the backfill material placed within the formerly mined JSLA open pit and the viability for its use as feed material in a potential Run-of-Mine heap leach program (ROM). The ROM program provides an opportunity to reprocess large volumes of sub 0.5 g/t material that was previously treated as waste.

“We are very pleased with the initial findings of the backfill drilling program as it confirms our opinion on the potential of the ‘old waste’ material as mineralized feed for a ROM heap leach. Armed with this data we intend on examining the merits of operating a modest sized ROM heap leach prior to the full restart of the permitted Castle Mountain Mine,” Marc Leduc, COO.

“The operational concept of reprocessing the ‘old waste’ material on a ROM heap leach pad could help benefit the project as we could potentially be back in production earlier. The ROM program provides us with the option of quickly restarting the operation as early as 2018, subject to initial capital financing,” added Leduc.

The JSLA open pit, mined between 1991 to 1996, was subsequently backfilled with blasted ROM ‘waste’ material from the Jumbo and Oro Belle open pits, located to the north, as the historical cut-off grade for mining was 0.50 g/t Au based on the prevailing gold prices.

The current surface drilling program is aimed at identifying where to start the pre-stripping of the starting pit.
