Only in the main area of the Cummins range rare earth project to achieve an excellent high-grade interception of up to 10.6% TREO
The latest results include a world-class intercept of 102.9m at 1.6% TREO, and more analysis is coming soon
For • RareX Company
RareX Limited (ASX: REE; or) is pleased to announce that it has conducted diamond drilling in the main area of the Cummins Range Rare Earths project, which has 100% equity in the Kimberley region of Western Australia, and has obtained more extensive and high-grade results.
The results-some of the results from CDX0002, CDX0003, CDX0004, CDX0005 and CDX0011-clearly demonstrate the great potential of the main area to include a wide range of high-grade mineralization zones, and strengthen the opportunity to significantly increase the current mineral resources 18.8Mt, 1.15% TREO 0.14% Nb2 O5 (indicated resources are 11.1Mt, 1.32% TREO 0.17% Nb2 O5; inferred resources are 7.7Mt, 0.88% TREO 0.151% Nb2 O5).

Jeremy Robinson, Managing Director of RareX, said: "These outstanding results have changed the rules of the game in Cummins. The diamond drilling completed at the end of the year aims to unlock the potential of major areas and show that we have the potential to be bigger and higher.
The grade item we have is here. These results strongly prove this belief.
"Part of the analysis from CDX0011 returned the highest grade ever recorded in the Cummins Mountains, including very high grade areas with a grade of 10.6% TREO-rare in such deposits. In addition, we have a world-class 103 meters in the well Intercept CDX0004, we have a very large primary mineralization zone in the area where previous prospectors believed that the mineralization was upgraded due to the weathering process, which is a very exciting development for the project.
"We look forward to obtaining a balance of analysis in this rapidly developing and growing deposit, and plan our next phase of exploration and use."
The analysis results of the borehole CDX0011 from 93m to 141.9m downhole have been received. This area has returned a very high-level result of 21.9m under 3.1% TREO, 0.6% NdPr and 0.2% Nb2 O5, including 3m at 10.6% TREO containing 1.8. % NdPr.
It is important that this new rock intersection is interpreted as the true width, and the previously announced hole from CRX0063 (41m @ 2.4% TREO, containing 0.5% NdPr and
0.5% Nb2 O5 ASX announcement, September 9, 2021). The hole is shown in Figures 1, 2 and 4.

The borehole CDX0004 measured up to 102.97m at 1.6% TREO, 0.3% NdPr and 0.4% Nb 2 O 5. The area where the hole was drilled was previously explained by previous prospectors as an area where rare earth minerals were upgraded through the weathering process. Instead, the hole has passed through the wide breccia zone at the hanging wall of the main fault.
The breccia zone has a uniformly wide interval of 1% to 2% TREO and strong niobium mineralization. As shown in the previously published borehole, this borehole was also drilled into the belt-CDX0007 61.4m, 1% TREO, 0.2% NdPr and 0.3% Nb2 O5 (75m westward) and CRX0066 40m, 1.8% TREO and 0.4% NdPr
And 0.3% Nb2 O5 (36 million northward) (ASX announcement November 10, 2021).
The rare earth and niobium grades seem to be increasing eastward, and the higher grade area of 2% TREO, 0.4% NdPr and 0.5% Nb2 O5 in the CDX0004 hole is 46.97m. The lower half of the breccia has a higher degree of mineralization and enters the interpretation position of the main fault, as shown in Figure 3.
The result of niobium immediately above the main fault is also very high, with an intercept of 9m under the conditions of 1% Nb2 O5 and 2.3% TREO.

The most notable is the shallow intercept in the CDX0002 hole-11.3m, containing 2.4% TREO and 0.4% NdPr and 0.2% Nb2 O5, including the very high grade range of 3.1m, containing 7% TREO and 1.8% NdPr. After receiving all the tests,
Only these new areas will be mapped to the entire deposit.
Hole CDX0003 produced high-grade results at the main fault location, 23.9m, 2.5% TREO, 0.5% NdPr and 0.3% Nb2 O5, including 2.3m, 7.3% TREO, 1.7% NdPr and 0.6% Nb2 O5. The hole is drilled as a filling of the oxide part of the resource and metallurgical drilling.
High-grade mineralization starts at 20m below the surface and is interpreted as >80% of the true width. Together with CDX0004, this hole will be used for a large number of metallurgical test work research conducted by local experts in Western Australia.
The use of diamond core drilling has significantly improved the geological understanding of Cummins Mountain deposits and continues to provide high-grade rare earth and niobium mineralization.
Many new zones on the hanging wall and footwall have been drilled to depths beyond expectations, which is very exciting. The shallow-wide breccia zone has better interception effects of rare earth niobium.
