High Grade Zinc, Copper, Lead and Silver Assays at Depth

at Gibsons in Step Out Holes

Critical Resources Limited (ASX:CRR) ("Critical Resources" or the "Company") is pleased to advise that it has received assay results from its 8th and 9th drill holes at its 100% owned Gibsons prospect. Diamond drill holes CRR21DD_02A ("Hole 02A") and CRR21DD_07A ("Hole 07A") have intersected further zinc, lead, copper and silver bearing zones of sulphide mineralisation. Hole 02A and Hole 07A are step out holes that further demonstrates the increased potential of the mineralised extent of the Halls Peak system.

Highlights

Hole 02A

• 6.37m @ 7.31% Zn, 0.89% Pb, 0.22% Cu, 10.33g/t Ag, 0.08g/t Au, from 72.65- 79.02m downhole
  o Including 2.01m @ 13.14% Zn, 1.82% Pb, 0.44% Cu, 17.20/t Ag, 0.09 g/t Au from 73.38-75.39m downhole
• 5.3m @ 4.10% Zn, 1.78% Pb, 0.49% Cu, 25.17g/t Ag, 0.09g/t Au from 166.3- 171.6m downhole

• Including 1.2m @ 9.4% Zn, 4.76% Pb, 1.29% Cu, 74.39g/t Ag, 0.16g/t Au from 170.4 - 171.6m downhole

Hole 07A

• 34.3m @ 2.14% Zn, 0.83% Pb, 0.32% Cu, 7.02g/t Ag, 0.05g/t Au from 70.3-104.6m downhole

• • Including 3.35m @ 6.06% Zn, 2.06% Pb, 0.23% Cu, 7.86g/t Ag, 0.02g/t Au from 83.55-86.9m downhole and
  • 4.5m @ 9.22% Zn, 4.34% Pb, 0.98% Cu, 23.81g/t Ag, 0.08g/t Au from 98-102.5m downhole
• Holes 02A and 07A are step-out holes in an area previously untested
• Strong mineralisation at depth continues to expand the potential of the Halls Peak System
• Cores from completed holes 02, 04, 14, 15 and 16 are currently being assayed at the ALS laboratory in Brisbane with results expected progressively

The Company is pleased to receive further assays from Hole 02A and Hole 07A at its 100% owned Halls Peak project in New South Wales. Results continue to demonstrate the scale potential of the Halls Peak system, particularly at depth and provides strong support for an expanded drill program.

Critical Resources Managing Director Alex Biggs said: "Further positive results confirm the growing potential of the Halls Peak system. As our drill program continues we are excited to see significant grades and intersections that provide increased confidence that Halls Peak could be a transformational asset for the Company. Our drill program is continuing and we look forward to starting drilling at our Sunnyside prospect which is approximately 1.5km along strike from our current drilling at the Gibsons prospect. This will add further growth potential to the Project".
