MAPA Certification Update

Harvest Minerals Limited, the AIM listed natural fertiliser producer, is pleased to announce that the application to register KPfértil, the Company's multi-nutrient natural fertiliser, has been processed by the Ministry of Agriculture ('MAPA') in Brazil, and that all questions and information requested have been provided.

MAPA is now required to conduct a site visit to the Company's Arapua project, most likely for later in April. It is anticipated that the registration will then be granted shortly after that.

Harvest's Executive Chairman, Brian McMaster, said, "The certification process for KPfértil as a remineraliser has taken longer than we initially thought, although I'd like to reiterate that there have been no issues with KPfértil itself. The delay has not impacted on our day to day activities or our ability to produce and sell KPfértil as demonstrated by the signing of a 36Kt sales contract at the start of the month. Our focus is now on growing sales and revenues and I look forward to providing further updates."

This announcement contains inside information for the purposes of Article 7 of EU Regulation 596/2014

Notes:

Harvest Minerals (HMI.L) is a Brazilian focused fertiliser producer and owner of the 100% owned Arapua Fertiliser Project, which produces KPfértil, a proven, multi-nutrient, slow release, organic fertiliser and remineraliser. KPfértil offers many economic and agronomic benefits and addresses the significant demand for locally produced fertiliser in Brazil, with its abundant agricultural land; currently, the country imports 90% of the potash it uses but has a target to be self-sufficient in fertilisers by 2020. Covering 14,946 hectares and located in the heart of the Brazilian agriculture belt in Minas Gerais, Arapua is a shallow, low cost mine with an indicated and inferred resource of 13.07Mt at 3.1% K2O and 2.49% P2O5. This is based on drilling just 6.7% of the known mineralisation, leaving significant upside potential. This resource is equivalent over 29 years' production and the known mineralisation expected to support 100+ years' production at 450,000 tonnes per annum.
