Latest Assays Confirm Widespread Rare Earth Mineralisation Over An Expanded Western Zone At Cowalinya

Heavy Rare Earths Limited (“HRE” or “the Company”) is pleased to report assays from another 118 air core holes from its recently completed 441-hole rare earth exploration and resource expansion drilling program at its 100 per cent-owned Cowalinya project in the Norseman-Esperance region of Western Australia.

• Assays received for additional 118 holes from HRE’s rare earth exploration and resource expansion drilling program at Cowalinya
  
• Further thick and/or high-grade rare earth intercepts reported
• Widespread rare earth mineralisation now occurs over 5 kilometres of strike and up to 3 kilometres wide in an expanded Western Zone
• New drill intersections include:
  • AC424: 6 metres @ 2597 ppm TREO (54.8% magnet REOs) from 9 metres and 4 metres @ 1976 ppm TREO (31.8% magnet REOs) from 21 metres
    
  • AC440: 14 metres @ 1278 ppm TREO (24.8% magnet REOs) from 14 metres
    • including 4 metres @ 3040 ppm TREO from 18 metres
  • AC361: 6 metres @ 1771 ppm TREO (23.9% magnet REOs) from 20 metres
    
    • including 4 metres @ 2489 ppm TREO from 22 metres
  • AC363: 10 metres @ 1200 ppm TREO (19.9% magnet REOs) from 30 metres
    
    • including 4 metres @ 2437 ppm TREO from 34 metres
  • AC412: 22 metres @ 1018 ppm TREO (24.7% magnet REOs) from 16 metres
    
    • including 2 metres @ 4087 ppm TREO from 18 metres
  • AC344: 12 metres @ 1212 ppm TREO (18.5% magnet REOs) from 22 metres
    
    • including 4 metres @ 2008 ppm TREO from 26 metres
  • AC418: 5 metres @ 1784 ppm TREO (24.2% magnet REOs) from 21 metres
    
  • AC269: 14 metres @ 1135 ppm TREO (25.3% magnet REOs) from 10 metres
    • including 4 metres @ 1646 ppm TREO from 12 metres
  • AC387: 21 metres @ 867 ppm TREO (25.1% magnet REOs) from 24 metres
  • AC312: 36 metres @ 656 ppm TREO (23.3% magnet REOs) from 18 metres

Most of these assays have been returned from holes in the newly discovered Western Zone of rare earth mineralisation (refer to ASX announcements 3 January 2023, 31 January 2023 and 1 March 2023) located west of and, in a significant expansion of this zone, south-west of the Cowalinya South resource¹. The Western Zone now strikes over a minimum of 5 kilometres and is 3 kilometres wide (Figure 1). It has an average thickness of 11.3 metres, a material increase on the ~9 metre average thickness of the Cowalinya resource².

Assays from 9 of 11 adjacent 200-metre-spaced holes in the Western Zone along 6358600N (AC303-AC313) feature 14- to 36-metre-thick mineralised intervals grading up to 814 ppm TREO. This line of holes is positioned mid-way between drill traverses for which cross- sections were presented in previous announcements (refer to section A-B in ASX announcement 3 January 2023, and section C-D in ASX announcement 1 March 2023).

Two kilometres further south along 6356600N, section A-B which measures 2.2 kilometres in length, comprises twelve 200-metre-spaced holes AC173-AC175 and AC410-AC418. Over half of these holes intersected thick and/or high-grade rare earth mineralisation as shown in Figure 2, and these intercepts are listed below:

• AC175: 22 metres @ 576 ppm TREO from 22 metres
• AC411: 20 metres @ 755 ppm TREO from 15 metres
• AC412: 22 metres @ 1018 ppm TREO from 16 metres
• AC413: 10 metres @ 747 ppm TREO from 17 metres
• AC415: 16 metres @ 929 ppm TREO from 11 metres
• AC417: 6 metres @ 1010 ppm TREO from 23 metres
• AC418: 5 metres @ 1784 ppm TREO from 21 metres.

Holes from the adjacent drill line 400 metres south also returned assays as high as 2597 ppm TREO over 6 metres.

Assays are awaited from another 30 holes which will complete the drilled extent of widespread saprolite-hosted rare earth mineralisation in the Western Zone on HRE’s E63/1972 tenement. They are expected to be reported during April.
