Harvest Minerals (HMI.L) is a South American focused fertiliser Company targeting low cost, near term development projects. The Company's primary focus is the development of its 100% owned Arapua Fertiliser Project from which it produces its KPfértil product, a proven, multi-nutrient, slow release, organic fertiliser and remineraliser, which is produced from a weathered potassium and phosphate rich lava and offers many economic and agronomic benefits. 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% K O and 2.49% P2O5. This resource translates into a mine life of over 100 years at a rate of 450k tonnes per annum and crucially is based on drilling just 6.7% of the known mineralisation, leaving significant upside potential. With a trial mining licence in place allowing Harvest to extract 50kt of

product on a rolling basis, whilst the full mining licence application process is underway, and official registration of KPfértil as a remineraliser expected by the end of 2017, Harvest is ideally placed to address the significant demand for locally produced fertiliser in Brazil; Brazil has abundant agricultural land but lacks domestic fertiliser, with the country currently importing 90% of the potash it uses. Furthermore, the Brazilian government has set a target to be self-sufficient in fertilisers by 2020, creating significant market opportunity for Harvest and its KPfértil product.

The Company has four assets at various stages of development and continues to explore other opportunities that fit its investment criteria.
