Harvest Minerals Limited announced that it has identified potential for Rare Earth Elements (?REE?) at its 100% owned Arapuá Fertiliser Project in Brazil (?Arapuá Project?). Highlights: Laboratory analysis of rock sample demonstrates the occurrence of REE with contents ranging from 1,176 ppm to 1,860 ppm of total rare earth oxides (?TREO?). A broader sample collection database characterized according to the degree of weathering has demonstrated REE contents from 549 ppm to 1,375 ppm TREO, not including analysis of all REE elements.

Historical laboratory analysis being validated by Harvest has indicated REE contents ranging from 1,837 ppm to 4,117 ppm TREO. REE-focused programme initiated to undertake re-assaying of substantial set of selected rock samples and drilling data for detailing of mineralization and potential association of REE with ionic clays. The Arapuá Project comprises nine exploration mineral rights covering a combined area of 14,481 hectares, spanning the Arapuá and Maximus blocks, which are owned by a subsidiary of Harvest's, Triunfo Mineracao do Brasil.

In 2017, Harvest disclosed its initial JORC compliant mineral resource estimate (?MRE?), indicating a total Indicated and Inferred Resource of 13.07 million tonnes at 3.1% K2O and 2.49% P2O5. This estimate was derived from drilling and exploration efforts, accounting for only 6.7% of the known mineralization. Throughout the exploration and drilling phases aimed at defining the MRE, a considerable number of samples were collected and are currently stored at the Arapuá Project's facilities.

Upon revisiting the laboratory analysis database for these samples, the presence of REE has been identified in the kamafugite rocks, the rock type associated with the Arapuá Project's mineral resources. Harvest has also identified in its sample collection database a total of 152 samples which have shown REE occurrences, although they have not been analysed for a number of REE elements such as Pr, Nd, Sm, Eu, Gd, Dy, Ho, Er and Tm. The analyzed samples were characterized according to their degree of weathering using the Chemical Index of Alteration (?CIA?).

The CIA was applied considering the potential association of REE with clays. However, this association still requires detailed investigation. These samples will undergo geochemical analysis to obtain the total concentration of REE.

Historical studies conducted within the Arapuá block, documented in a report titled ?Capacete Project Audit Report?, which was obtained by Harvest during the acquisition of the Arapuá project, also highlighted significant REE findings from samples collected in the Arapuá block. Harvest is presently engaged in sample collection from the same locations within an area known as the Capacete area, as part of its own data verification process.
