Castillo Copper releases drilling results at Broken Hill

Highlights:

• Assays from seven drill-holes across FG and TT prospects, confirm a significant shallow clay-hosted REE discovery – up to 2410 ppm TREO, with high-value Magnet REOs representing up to 29.9% of the grade – the best intercepts comprise:
  • 20 m @ 1780ppm TREO (28.9% Magnet REO) from surface including 4 m @ 2410 ppm TREO from 16 m (FG_003RC).
  • 7 m @ 1048 ppm TREO (29.9% Magnet REO) from 12 m (TT_002RC).
  • 19 m @ 847 ppm TREO (29.6% Magnet REO) from surface (TT_003RC).
  • 8 m @ 773 ppm TREO (24.0% Magnet REO) from 48 m (FG_004RC).
  • 4 m @ 732 ppm TREO (27.1% Magnet REO) from 24 m (TT_001RC).
  • 19 m @ 661 ppm TREO (28.0% Magnet REO) from surface (FG_002RC).
  • 32 m @ 636 ppm TREO (25.7% Magnet REO) from 52 m (FG_003RC).
  • 28 m @ 614 ppm TREO (27.8% Magnet REO) from 4 m (FG_004RC).
• Assays from FG_001RC are still pending, however, results for FG_002-4RC delineate an initial 800 m strike event starting near FG’s eastern boundary:
  • Further, with REE mineralisation open in all directions, and FG circa 4 km long by 1 km wide (W-E), the board has ordered follow up geological mapping, sampling and auger drilling to target extending the known strike event to the west.
• While cobalt assays met expectations, the new discovery has pivoted the board’s strategic focus for the current drilling campaign and beyond to fully understanding the extent of REE mineralisation across the BHA project’s east zone.

Ged Hall, Chairman of Castillo Copper, commented:

“With global demand for REEs on an upward trajectory, the board is delighted the assays confirm a new shallow clay hosted REE discovery within the BHA project’s east zone. In particular, the board notes drill-hole FG_003RC which intersected an aggregate 52 m of REE mineralisation. This is a game-changing event for the group, as exploration efforts moving forward are going to focus on extending known REE mineralisation, especially at the Fence Gossan and Iron Blow prospects in due course.”
