Harvest Minerals Limited
("Harvest" or the "Company")
Excellent Coffee Agronomic Test Results from the Arapua
Fertiliser Project
Harvest Minerals Limited, the AIM quoted fertiliser development
company, is pleased to announce further positive results from the
ongoing agronomic test work conducted on KPfértil, its direct
application natural fertiliser and remineraliser product produced
from the Company's 100% owned Arapua Fertiliser Project in Brazil
("Arapua").
Highlights
-- Results of tests conducted over 180 days on juvenile (+/-1.5
year) and mature (+12 year) coffee plants indicate that KPfértil, a
completely natural, slow release, single product fertiliser, is as
effective as traditional fertilisers in supplying potassium ("K")
and phosphate ("P") to plants
-- As part of the test, a total of 12 treatments were applied to
compare KPfértil to conventional fertilisers as a source of K and
P
-- Results are part of the ongoing agronomic efficiency study on
the application of KPfértil on coffee crops
-- Further tests will be conducted to examine the long-term
benefits of using KPfértil over conventional fertilisers
Santinato & Santinato Cafés Ltda ('Santinato'), a renowned
agronomic consulting company in Brazil specialising in coffee
cultivation, conducted the tests at one of the Veloso Agropecuária
('Veloso') coffee plantations. Veloso is considered one of the
largest coffee producers in the Brazilian Cerrado.
Harvest's Executive Chairman, Brian McMaster, said, "These
results are excellent and build on the successful tests carried out
on rice crops which demonstrated a substantial increase in dry
matter production following the application of KPfértil. We have
identified the coffee growers in the Cerrado Region as an important
customer base and tests results indicating that our local, 100%
organic product acts as efficiently as imported KCl, a conventional
source of potassium, represent a significant outcome for Harvest.
We expect further results from these tests over the coming months,
but our focus is now on registering KPfértil with the Ministry of
Agriculture, Livestock and Supply ('MAPA') and achieving our first
sales. Supported by the test results we have received to date we
have been introducing KPfértil to potential end-users and
distributors."
Further Information - Agronomic Efficiency Study in Coffee
Crops
The purpose of the study is to compare the effects of applying
KPfértil against conventional fertilisers as a source of K and P in
both juvenile (+/-1.5 years old) and mature (+12 years old) coffee
plants. A total of twelve treatments were applied to both the
juvenile and mature coffee plants, being six for potassium (table
1) and six for phosphate (table 2).

After the treatments had been applied for 180 days, the coffee
plants were harvested and submitted for biometric evaluation, which
is one of the main indicators of agronomic efficiency. At this
first stage the biometric measurements used were the offshoot
length, the number of nodes and the internode length.

and coffee straw applied to juvenile coffee plants
Results
The detailed results of the test are contained in Tables 3
through 6 below.
These tests were conducted over a relatively short time frame of
180 days. However, even over this short time frame, it was
demonstrated that there was no statistical difference in the
biometric parameters between KPfértil and KCl at the 100% dose for
both juvenile and mature coffee plants.

Notes:
Harvest Minerals (HMI.L) is a Brazilian 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(2) O and 2.49% P(2) O(5) . 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.
