Critical Resources Limited advise that it has encountered further visual Massive and Base Metal Sulphides in its sixth diamond drill hole (Hole 09) of its drilling campaign at the Gibsons prospect, part of the broader Halls Peak project in New South Wales. Visual Massive and Base Metal Sulphides have been encountered between 56.2m and 61.5m downhole and down to 138m, a depth previously undiscovered indicating further depth potential of the Halls Peak system. Visual Massive and Base Metal Sulphide intervals have been intersected in Hole 09 between 56.2m and 61.5m downhole 1 Base Metal Sulphides also detected as deep as 138m - a depth previously undiscovered 1. Results indicate further depth potential of the Halls Peak system Hole 09 is a step-out hole and represents new mineralisation.

Drill rig currently drilling hole CRR21DD_08A. Cores from previously reported drilling are being assayed at the ALS laboratory in Brisbane with results expected in the short term. Drilling has recommenced at Gibsons after the Christmas break with ~2,500m planned including a subsequent 3-hole drill program at the Sunnyside prospect for ~1,700m.

Holes are designed to confirm near surface mineralisation and deeper targets to a maximum depth of up to 500m. The following base metal sulphide contents are visual estimates (estimated combined percentages of sphalerite -zinc mineral, galena-lead mineral, chalcopyrites-copper mineral). Quantitative assays will be completed by an ALS laboratory in Brisbane 56.2-57.05m: 20% base metal sulphide.

57.05-57.8m: 55-60% massive base metal sulphide. 57.8-59.8m: 20% base metal sulphide. 59.8-61m: sparse base metal sulphide.

61-61.5m: sparse base metal sulphide. 132.6-138.1m: Foliated black carbonaceous shale with intermittent intervals of base metal sulphides (dominantly sphalerite with lesser galena). 140-143.8m: Foliated black carbonaceous pelite with abundant fine disseminated pyrite with possible minor base metals.

148-149.5m: Estimated to contain 5-10% pyrite as clots and discontinuous foliations with possible minor base metals in foliated black carbonaceous pelite. The presence of minor base metal sulphides in the interval 132.6-138.1 metres extends the down hole depth of the known base metal exhalative system and indicates potential for discovery of further massive sulphide lodes both laterally and at depth.
