Mallina Gold Project

About the Mallina Gold Project

The Mallina Gold Project (MGP) is a 1,200km2 contiguous tenement package which has been consolidated by De Grey over a period of several years. The landholding gives the company a dominant position in the Mallina Basin of the Pilbara region.

In late 2019 a major gold discovery was made at Hemi in the central area of the MGP. Gold mineralisation at Hemi is hosted in a series of intrusives associated with stringer and disseminated sulphide rich zones. This style of mineralisation is new to the Pilbara region and shows a scale of mineralisation not previously seen in the Mallina Basin.

There are at least four look-alike intrusion targets already identified in the immediate vicinity of Hemi: Scooby, Shaggy, Antwerp and Alectroenas. Three already host known shallow gold mineralisation with the fourth, Alectroenas, never previously drilled.

Six drill rigs are currently operating at the MGP in a combination of aircore, RC and diamond drilling.

The Company has a three-tiered exploration strategy at the MGP following the discovery of the Hemi deposit in late 2019:

  • Hemi: aspirational goal of establishing Tier 1 production potential from Hemi and nearby zones by proving significant extensions to the mineralisation footprint and at depth using RC and diamond drilling.
  • Greater Hemi and shear-hosted opportunities: delineate the known mineralised intrusives around Hemi and use aeromagnetics and aircore drilling to test for new intrusions throughout the MGP.
  • Other MGP resources: test for other mineralisation styles across the 200km of shear zones and continue to incrementally expand the existing 2.2Moz resource outside Hemi.
