Think it’s all about Hemi for De Grey Mining? Think again, with the exciting gold explorer racking up some encouraging hits from regional exploration at the 9Moz Mallina gold project. The new results open up a potentially larger corridor that can potentially deliver further Hemi-style discoveries on De Grey’s 100% owned ground.

While the maiden 6.8Moz Hemi intrusion has rightly stolen the headlines, there’s about to become more focus on new targets De Grey (ASX:DEG) has uncovered at its Pilbara gold project with resource definition drilling complete ahead of an update later this quarter.

RC and aircore drilling has recently been completed at the Charity Well and Geemas prospects in the western end of the Mallina project.

Three recent RC holes drilled as part of a larger program at Charity Well included 18m at 1.5g/t gold from 23m, 6m at 2.8g/t from 139m and 13m at 1.1g/t from 221m in a single hole, 15m at 1.1g/t from 81m and 18m at 0.6g/t from 318m ending in mineralisation.

Aircore drilling has been equally promising, hitting 30m at 0.4g/t from 4m, 37m at 0.6g/t from 8m and 4m at 3.4g/t from 16m.

Those results have extended intrusion-hosted mineralisation at Charity Well to 1km of strike, remaining open to the northeast and at depth. That’s around double of the size of the target intrusion originally identified in RAB drilling.

It is located just 4km to the north of the 524,100oz intrusion hosted Toweranna gold deposit which contributed a not insignificant 300,000oz of free milling gold to the mineable resource in last year’s Mallina scoping study.

But wait, there’s more

Follow up RC drilling at Geemas, 12km southwest of Charity Well in the same structural corridor, also hit intrusion-hosted gold mineralisation, which is popping up just about everywhere on De Grey’s extensive tenement package.

New results from Geemas included:

  • 1m at 4.5g/t Au from 33m and 5m @ 2.2g/t Au from 91m in MWRC0202, and;
  • 2m at 1.2g/t Au from 3m and 3m at 1.1g/t Au from 64m in MWRC0197.

Like Charity Well, drilling at Geemas is starting to reveal its true scale. The intrusion has been confirmed to have a strike length in the order of 800m and is 300m wide with smaller, subordinate intrusions nearby. The new results at Charity Well open up a potentially larger corridor to the northeast and delivering plenty of potential for more Hemi-style discoveries.

“These new regional exploration drilling results at Charity Well and Geemas demonstrate the potential for De Grey to make new discoveries of intrusion-hosted gold deposits in prospective geological settings across our regional tenement package,” DEG General Manager of Exploration Phil Tornatora said.

“The new results at Charity Well open up a 20km prospective structural corridor running to the northeast of Charity Well and intersecting the east-west Withnell-Mallina trend.

“Work is also currently underway around Withnell and will shortly commence in the Blue Moon area, located to the west of the Gillies prospect.”
