Greatland Gold using MMI to pinpoint gold mineralisation

Greatland Gold, a precious and base metals exploration and development company, has begun a Mobile Metal Ion (MMI) surface geochemistry survey at Ernest Giles East. In addition, a ground gravity survey across Ernest Giles East is expected to commence within the next few weeks. Results of the exploration program are expected to be disclosed in September 2017.

  • Exploration work seeks to demonstrate the broader potential for gold mineralisation
  • Greatland’s technical team has begun a 3.2 km by 400 m spaced MMI survey, and the company expects to commence a 1.6 km by 200 m spaced gravity survey across the same area within the next few weeks
  • Results from these surveys will be used to establish gold exploration targets on these new licences for follow up work and drilling.

The Ernest Giles East area covers approximately 600 km2, including a large 80 km long north-south trending sequence of rocks which represent an extension of the gold prospective Ernest Giles greenstone sequences. This exploration program follows on from recent significant developments at the project including the identification of two large zones of gold mineralisation at the Meadows target in the southwest corner of the project, and an agreement with Newmont Exploration Pty, a subsidiary of Newmont Mining.

Mobile Metal Ion (MMI) geochemistry is a proven advanced geochemical exploration technique known to find mineral deposits. It is especially well suited for deeply buried mineral deposits. MMI™ measures metal ions that travel upward from mineralization to unconsolidated surface materials such soil, till, sand and so on. These mobile metal ions are released from mineralized material and travel upward toward the surface. Using careful soil sampling strategies, sophisticated chemical ligands and ultra sensitive instrumentation, SGS is able to measure these ions. After interpretation, MMI data can indicate anomalous areas. SGS is the sole provider of MMI technology.

Gervaise Heddle, Chief Executive Officer, commented: “This survey is a natural progression following successful demonstration last year of the presence of large zones of gold mineralisation on the Western side of the Ernest Giles project. We hope that this new exploration program will highlight the prospectivity of the new Eastern licences; licence areas where virtually no modern exploration has taken place, and confirm our belief in the potential of this exciting new gold district to host several multi-million ounce deposits.”
