New rare earth discovery 52 km from Deep Leads
Thicker higher grades
Discovery ofhigh grade REEatPortrush 52 km east of Deep Leads
ABx Group (ABx) has discovered a new rare earth element (REE) prospect at Portrush located 52 km east of ABx's Deep Leads REE project in northern Tasmania (see Figure 1)
Results from Portrush include hole PR033 grading 4,800 ppm total rare earth oxides (TREO)

Deep Leads drill program delivered thicker, highergrade REEresults:
Latest results at Deep Leads indicate thicker and higher-grade mineralisation. Holes at Deep Leads were stopped by the wet clays and broken ground of the mineralised horizon
Those holes that penetrated further into the mineralisation show a wide distribution of thicker, higher grade REE mineralisation that extends for several kms
The best intercept to date in hole DL190 is 5m thick, including a metre at 3,943ppm TREO
Discovery holes DL190, DL409 and DL403 confirm that the deposit continues strongly tothe southeast and west - see Figures 2 and 3
A more powerful multi-purpose drill rig is being deployed to drill major step-out holes

37 holes at Wind Break project returned strong REE mineralisation at the bottom of the holes
Four of the holes had grades from 1,000 to above 1,500ppm TREO and two of the holes encountered mineralisation 4 m thick. All holes at Wind Break ended in REE mineralisation
ABx exploration manager, Paul Glover commented; "We are discovering better grades and thicker mineralisation over a much larger province than thought possible."
ABx operations manager, Nathan Towns commented; "Our next drill program will sample the full thickness of this shallow, clay-hosted REE and give us some indications of how large these discoveries can be. It's time to step-out much wider."
ABx REE discoveries across northern Tasmania
ABx is an emerging hi-technology and explorer-developer company that is the first company to discover clay-hosted REE in northern Tasmania, initially at Deep Leads. ABx's latest assay results confirm that ABx has now made REE discoveries in three locations (see Figure 1):
- Deep Leads project
- Wind Break project located 16 km northeast of Deep Leads
- Portrush project located 52 km east of Deep Leads
Deep Leads project
In the latest drilling program, several holes were able to penetrate deeper into the REE mineralisation zone before becoming stuck. Without special equipment, drill rods become bogged in wet clays and drill bits get stuck in broken ground.
REE intercepts from those holes that penetrated further into the mineralisation are:

Discovery hole. DL190 is considered to be a discovery hole because it intersected 5m of REE mineralisation and included the highest grades at Deep Leads to date (3,943 ppm TREO).
DL190 is the southernmost hole, indicating a strengthening REE mineralisation trend towards the south-east which could extend for a considerable distance and is currently unexplored - (see Figure 2).

DL187 is a shallow hole that is more enriched in cerium than usual, which usually occurs in samples above the main REE mineralised zone. DL187 is a strongly mineralised intercept, and a new hole is planned nearby to test to at least 15 metres depth.

DL409 is located in the south-westernmost corner of the drilled area, which indicates that the southwestern edge of the plateau is well mineralised.

DL403 discovered a thick, high-grade intercept in a high-grade area that is open to the northwest (see Figure 2). Hole DL403 ended still in high-grade REE mineralisation.
Step-out drilling target
A work-program has been designed to drill holes to significantly expand the drill coverage of the REE mineralisation at Deep Leads as shown in Figure 3.
