UPDATE ON RARE EARTH EXPLORATION

Harvest Minerals Limited, the AIM listed fertiliser producer, provides an update on the latest REE exploration activities at its 100% owned Arapuá Project in Brazil ('Arapuá').

OVERVIEW

§ Exploration work to date has been conducted in consultation with PVW Resources Limited ("PVW"), through the cooperation agreement previously announced.

§ A further 36 historical samples were selected in consultation with PVW and sent for analysis.

§ Encouraging average TREO concentrations ranging from 2,110.53 to 2,656.99 ppm.

§ Confirmation of REE presence in "Bone" lithotype.

§ TiO₂ grades within the mineralized TREO intervals range from 12.55% to 15.42%.

§ Further RC Drilling and Sampling is planned.

§ Given the continued encouraging results, Harvest has advised PVW Resources that it will accelerate exploration activity directly as contemplated by the cooperation agreement

Brian McMaster, Chairman of Harvest, said: "Todays results continue the trend of encouraging and exciting results from our Arapuá Rare Earth Elements ("REE") project.  Whilst we are delighted to benefit form the technical expertise of PVW, Harvest will continue the next round of exploration directly in order to accelerate the programme. We have created a high-impact, low-cost exploration programme for the next phase, which is expected to get underway shortly. This coincides with the recent uptick in the fertilizer business as reported earlier this week (see RNS 16 June 2025).

FURTHER INFORMATION

A total of 36 additional historical samples from Pimentas I and Pimentas II targets were analysed by SGS Geosol with Protocol IMS95A for 48 elements in a new lithotype called "Bone" returning very promising results with average TREO concentrations per drill hole ranging from 2,110.53 to 2,656.99 ppm.

Additionally, the TiO₂ grades within the mineralized TREO intervals range from 12.55% to 15.42%. These results indicate a consistently high titanium content associated with the rare earth mineralization.

The next phase of exploration is due to commence in Q3 with an estimated cost of US$100,000, which will be funded from existing resources, and is to drill around 700 meters, generating around 700 samples, one for each meter and conduct laboratory tests. It is expected the RC drilling programme will take 30-45 days from mobilisation, with subsequent lab results from the assays reported shortly thereafter.
