PRESS RELEASE: 2nd LiDAR study confirms an extended GDM Devil’s Mountain opportunity

Latest Press Release

Great Divide Mining Ltd (ASX:GDM) announced today the completion of a second independent 3rd party study of LiDAR data at its Devils Mountain project.

Based on Queensland Government survey data, the second survey extended the first LiDAR survey’s results to the Kilkivan Prospect area and re-confirmed the prospectivity of GDM’s tenements at its’ Devils Mountain project.
Undertaken by specialists GeoCloud Analytics the interpretation indicated a total of 486 potential historical mine workings, including 40 adits, 16 shafts and 430 other known prospecting pits. Many of the old workings were not previously known to GDM.

“Aggregated with our first survey results delivers to GDM over 650 known & independently confirmed historical mine workings, including 23 shafts,” said GDM CEO Justin Haines.
GDM’s Devils Mountain Project comprises 5 x EPMs (17685, 26062, 26135, 26709, 28438) located ~30 km northwest of Gympie. Highly prospective for gold the region is also known for copper, silver, lead, tungsten, mercury and manganese. The region’s geology is very similar to the proven and nearby Gympie gold fields.

Adding the Kilkivan prospects area, over EPM 26135, a total of 80 km2, the new LiDAR dataset has allowed GDM to get a more accurate picture of historical gold mining at Devils Mountain,” said Haines. “Shafts and adits are good indicators of the presence of significant gold mineralisation, because of the effort invested in manually producing those old excavations.”

“The LiDAR results have now twice confirmed GDM’s strategy of targeting areas of abundant historical workings and applying modern exploration technologies to those sites”, he said.

“At GDM we say… Plan Twice … Dig Once !” said Haines
