CZR Resources Limited announced exploration is ramping up at its Croydon Gold Project in the Pilbara ahead of drilling in the coming quarter. The Croydon project is located in the Mallina Basin between Karratha and Port Hedland. The region contains De Grey Mining Limited's (DEG) Hemi gold deposit, which has an 8.5Moz resource.

The Mallina Basin has the potential to emerge as a major gold province and CZR's Croydon project covers approximately 40km strike of the Mallina Basin, about 70km south-east of Hemi. Gold mineralisation at Hemi is hosted in a series of intermediate intrusions associated with sulphide (pyrite and arsenopyrite) stringers and disseminations within brecciated and altered quartz diorites that intrude into the surrounding Archaean aged Mallina Basin sediments. Magnetic surveys, particularly over the Western target, are relatively ineffective at detecting buried, or `blind', intrusions due to the overlying Mallina Basin sediments.

Ground based gravity differentiates density contrasts between different rock types, in particular lower density intrusions next to higher density mafic and ultramafic rocks, which is the target setting for gold mineralisation at Croydon. A total of 4,000 gravity stations are planned over the Western and Eastern targets, at a nominal 100m station x 200m line spacing. The data collection is expected to be completed by mid-late December, with 3D inversion modelling planned early in the March 2023 quarter.

Priority drill targets, using the newly acquired gravity data and existing geochemical data will then be tested later in the March 2023 quarter, weather and approvals permitting.
