Marimaca Copper Corp. (“Marimaca Copper” or the “Company”)
(TSX: MARI) is pleased to provide a summary of the
metallurgical test work which has been completed for its flagship
Marimaca Copper Project (“Marimaca” or “the Project”), as well as
an outline of the current detailed metallurgical work, which is
ongoing and is expected to be completed in the current quarter.
Highlights
- The three phases of column
and bottle roll test work already completed indicated fast leaching
and favourable recoveries, especially in the dominant oxide mineral
zones which comprise the majority of the deposit-
Average 84% recovery of the total copper was obtained in bottle
roll testing completed on ore samples taken from mineral zones
comprising the expected early years of mine life--
Average recoveries were 4.8% higher than average acid soluble
copper across all samples-- Indicates leaching
recovery, in a heap leach operation, is likely to exceed the acid
soluble copper percentage for the mineral sub-zones of
Marimaca
- Phase 4 test work is
underway and expected to be completed later this month with results
to be released during Q3- Includes material from
La Atomica and Atahualpa which were outside of the original mine
plan - Tests will include acid leaching with
seawater, with and without added chloride ions, conducted in bottle
rolls; 30cm mini-columns; 1.5m columns; and in a ROM
leach characterisation for low grade
material
- Phase 5 test work will
commence in Q3 to further refine results from first four phases and
address variability across the deposit
Michael Haworth, Executive Chairman of
Marimaca Copper commented:
“Metallurgy is one of the key de-risking
milestones to address in the development of any mining project. For
Marimaca, we have already completed multiple phases of test work to
assess the deposit’s metallurgical characteristics.
“The results have been very pleasing, especially
with respect to the materials which approximately comprise the
first five years of the potential mine life, which is the all
important payback period. The results show recoveries of over 84%
of total copper, on average, in laboratory scale testing. Perhaps
most importantly, these results exceeded the expected acid
solubility ratio of the ore samples tested. This means that some of
the minor copper bearing minerals, which weren’t initially
identified as acid soluble, are also amenable to acid leaching and
gives us great optimism for the potential for higher recoveries in
an eventual heap leaching operation.
“It is also clear that, with the amount of
technical work and de-risking milestones achieved already, we are
well ahead of a typical PEA stage of development. The Phase 4
metallurgical program, which is due to be completed later this
month and released during the third quarter, will significantly
advance our knowledge and provide additional data across many parts
of the deposit. This will provide the Company with a robust
geometallurgical model which, in turn, will allow a detailed life
of mine analysis of metallurgical recoveries for future studies.
Phase 5, which is expected to commence in the 3rd quarter of this
year, will allow us to focus on optimizing a very exciting copper
project, as we move into the next phases of study.”
Marimaca Copper Project Overview
Marimaca Copper released an updated Mineral
Resource Estimate (“MRE”) for Marimaca of 70 million tonnes, with
an average grade of 0.60% total copper, within the Measured &
Indicated Categories (approximately 420Kt of contained copper) and
40 million tonnes, with an average grade of 0.52% total copper,
within the Inferred Category (approximately 224kt of contained
copper) (refer release on 2 December 2019). This
represents an increase of almost 100% from the MRE released in
April 2018 and makes the Project one of the most significant copper
oxide discoveries in Chile in the last decade.
The Company is currently undertaking a PEA for
the Project, which is anticipated to be completed in July 2020. The
Project is expected to benefit from low upfront capital development
costs and, due to the favourable geometry of the orebody and
relatively simple oxide processing through SX-EW, management
believes the Project will have very competitive operating costs,
delivering compelling economics in the PEA.
Overview of Metallurgical Test Work
Programs Completed
The Company has completed three phases of
metallurgical test work between April 2017 and March 2018, with a
fourth phase currently underway and expected to be completed and
released to the market in the coming months. A fifth phase,
which extends the previous programs will commence in the 3rd
quarter of 2020. The results of Phases 1, 2 and 3 were included in
the NI43-101 Definitive Feasibility Study for Marimaca 1-23,
released on the 29th of June 2018.
These tests have been carried out by Geomet
S.A., a well known Chilean laboratory with considerable experience
in metallurgical programs for copper deposits in Chile. Phase 4 has
been designed and executed under the supervision of Marcelo Jo of
Jo & Loyola Process Consultants, who has 35 years’ experience
in processing. He is supported by Randolph E. Scheffel, a
Consultant Metallurgical Engineer with over 35 years’ experience in
copper processing.
These tests were completed on materials obtained
from Marimaca to characterise the metallurgical response of the
deposit to different operational conditions. The first three phases
were performed on a variety of parameters including agglomeration
conditions, granulometry, column height, irrigation rates and acid
consumption. These tests were followed up with more detailed
analysis including bottle roll Iso-pH tests.
The fourth phase program, which is almost
complete, comprises broader, more detailed and rigorous programs,
which will provide the final technical data and information
required for a Preliminary Feasibility Study.
A fifth phase will be undertaken to refine any
remaining areas of potential risk or gaps in information and
knowledge of the Project. This will likely include optimisation of
both acid consumption and recoveries, as well as addressing
variability across the deposit, and providing information for the
completion of a Definitive Feasibility Study.

locations of samples used in Geomet Phase 1-2-3-4 testing
programs.

METALLURGICAL TESTING PHASES 1 &
2
The first two phases of metallurgical test work,
carried out in April and September 2017, were preliminary in nature
and designed to characterize the Marimaca Project’s copper oxide
metallurgical response. Seven composite samples were prepared for
column leaching tests, considering the mineral zones of the deposit
which were identified at that time.
The copper oxide species present are
brochantite, atacamite, chrysocolla and copper wad. The observed
gangue minerals include scarce calcite. Most of the oxides occur as
fractures impregnation and filling.
The following table shows the chemical
characterization of each sample, the main copper species and
composite location.

Testing Phases 1 & 2
Description of the Tests
In April 2017, Geomet S.A. laboratory was
commissioned to start Phase 1 of the initial metallurgical program
which included the mechanical preparation of the ore samples, its
characterization, head granulometry analysis, sulphation tests,
ISO-pH tests, leaching tests at two granulometries in seven columns
of 6” diameter and 1 meter height in duplicate, tailings
analysis was considered for each test. A key outcome of the tests
was the estimation of potential copper dissolution that may be
expected in a leaching operation, which is the ratio of acid
soluble copper (CuS %) to total copper in a sample (CuT %) (the
acid Solubility Ratio), as shown in the above table. The laboratory
procedure to determine CuS is to contact a 1 g of pulverized ore
sample with 50ml of sulfuric acid solution at 5% v/w, while
agitating for one hour and analyze the copper dissolution.
Based on the previous Phase 1 results, Geomet
S.A. was commissioned in September 2017 to execute Phase 2 of the
metallurgical program using the same samples, which considered more
specific parameters to further optimize the testing results, to
inform future process design parameters, including:
- Particle size: - 90% below half inch
- Irrigation Rate – reductions in irrigation rates from phase one
to find an optimal rate
- Acid in Agglomeration – sulphation tests to identify acid
deficit and triangulate optimal acid application
- Column Leaching – Tests performed at different heights ranging
from 1.6m to 3.0m
- Leaching time, application rate and acid consumption
Conclusions
The overall metallurgical response from the
first phase showed favourable results supporting good recoveries
for the different ore samples tested.
Leach kinetics were rapid with 70% to 80% of
total copper recovered within the first one third of the leach
cycle. Recoveries ranged from 77% +-3% for the Chrysocolla to 58%
+-3% for the mix of primary sulphide and supergene oxides. Average
acid consumption across the samples was, on average, slightly over
40kg/t, indicating a mid range acid consumption profile. The table

Metallurgical Results per Sample
Given the preliminary nature of this testing, it
was expected that significant further optimisation and improvement
would be achieved in following test work campaigns with respect to
recovery and acid consumption.
METALLURGICAL TESTING PHASE
3
Phase 3 testing, which was completed in March
2018, was primarily focused on defining the metallurgical response
on ore samples which would be expected to be representative of the
first five years of extraction. For this reason, the samples tested
had a higher proportion of brochantite/atacamite and chrysocolla.
37 composites from 13 drill holes were selected, 10 reverse
circulation (RC) and 3 diamond drill holes (DDH).
Test Description
This test program included the head chemical
characterization of all composites (CuT, CuS, FeT, Al, Mg, CAA,
CO3, AlS, FeTS and MgS) and the completion of 42 iso-pH 1.5 tests,
37 of them at 48hrs and 5 at 72 hrs.
Main Results
The results of the bottle tests are summarized
in table 3 below.
Virtually all samples show total copper
recoveries which exceeded the acid solubility ratio for the sample.
This confirmed the work completed and results received in Phases 1
& 2.

Table 3: Iso-pH tests, CuT recovery and
acid consumption
Conclusions
For the 42 samples, average recoveries exceeded
the acid solubility ratio of the samples by nearly 5%.
The average total copper extraction was 84.15%,
and the average of the acid solubility ratio was 79.4% across the
samples.
This confirmed the conclusion from previous test
work, that a portion of the acid insoluble copper, in some cases a
very meaningful portion, was dissolved. This also agrees with the
assessment of the likelihood of leaching potential of the materials
tested to exceed the acid solubility ratio. This is thought to be a
result of the increased exposure time to acid – in the case of the
bottle rolls, exposure time of 5hrs and 72hrs, when compared to 1hr
in the initial acid solubility test.
The average net acid consumption across the
samples was 39.3 kg/t continuing to indicate a mid range acid
consumer. It should be noted that acid consumption may be further
optimised by adjusting concentrations, but this work will be
completed in later phases of testing.
METALLURGICAL TESTING PHASE
4
The Phase 4 metallurgical test work program
commenced in January 2020 and is expected to be completed by the
end of June 2020 and released during the 3rd quarter.
Following on from the results received in Phases 1, 2 and 3,
this phase was designed to be broader in its coverage of the
metallurgical response of Marimaca, providing significantly more
detail with respect to certain mineralisation sub zones and
addressing some aspects of variability across the deposit.
Composite samples were taken considering the
updated mineral subzones, which are now defined as follows:
- Bronchantite / Atacamite;
- Chrysocolla;
- Wad;
- Mixed; and
- Enriched.
Each zone has different copper mineral species
and, it was noted, in the tests conducted in the Phase 3 program,
the overall leaching recovery exceeded the acid solubility ratio
across the samples. Assessing the leaching characteristics of each
subzone, and their true leaching potential, will be an important
step in developing a robust geometallurgical model, which can
consider variability across the deposit and provide data to
optimize future design.
The solubility ratio for copper oxides such as
atacamite, brochantite and chrysocolla, which dissolve quickly when
exposed to acid, is a good predictor of leachability. However,
where the minerlization has several copper bearing minerals with
different dissolution characteristics under these leaching
conditions, the copper acid solubility ratio may underestimate the
acid leaching potential for heap leach operations, especially where
some copper sulphides such as chalcocite, covellite and bornite are
present, as these sulphides could be partially dissolved under
oxidation conditions.
For this reason, it is also common to assay for
cyanide soluble copper when assaying copper oxide samples. This
gives an indication of the total leaching potential because cyanide
dissolves some of the copper sulphides that may be present in the
sample and assumes that, during the leaching operation, some
oxidation reactions, such as, ferric leaching and/or cupric
chloride leaching occur. Due to these reactions during
sulphide leaching it can be inferred that copper dissolution in a
leaching operation may materially exceed the copper acid solubility
ratio identified. Phase 4 metallurgical testing is addressing this
point through both mini column and 1.5 m column testing under
different leaching conditions.
Tests being undertaken in Phase 4 include:
- Head Chemical Characterization with sequential copper
analysis
- Particle size characterization
- 1.5 iso-pH test with and without seawater
- Acid and chloride leaching tests in 30 cm mini-columns
- 1.5 m columns tests; and
- ROM leaching in 1m3 iso containers of a low grade wad sample
with minor presence of chrysocolla, atacamite and secondary
sulphides.
METALLURGICAL TESTING PHASE
5
Phase 5 metallurgical testing will be informed
by the results and synthesis of information obtained in all the
previous metallurgical testing programs. Scoping is currently
underway for this work and the Company expects that this will
provide sufficient information required for a bankable feasibility
study and to move into detailed design and engineering.
The test work program will consider parameters
including, but not limited to, agglomeration conditions, column
height, granulometry, irrigation rate, acid concentration and
leaching cycle time.
A core objective of the Phase 5 test plan is to
complete the full evaluation of metallurgical variability of the
resource, extending on the variability work which is being competed
as part of the Phase 4 program. The sample base used in this
program will be much larger and will provide data on multiple
permutations of mineral sub-zone which may be expected during
operations.

Marimaca Copper and the Marimaca Project
Marimaca is fast becoming recognised as one of
the most significant copper discoveries in Chile in recent years as
it represents a new type of deposit which challenges accepted
exploration wisdom and promises to open up new frontiers for
discoveries elsewhere in the country. Marimaca is hosted by
intrusive rocks while the numerous manto deposits in the same
region are hosted by volcanics. With a lack of new copper
exploration discoveries in Chile, the growing Marimaca resource is
a high-profile development project as it is situated in the coastal
belt at low elevation close to Antofagasta and Mejillones. This
prime location could enable its future development at a reduce
capital cost relative to many other copper developments. Marimaca
will benefit from nearby existing infrastructure including roads,
powerlines, ports, a sulphuric acid plant, a skilled workforce and
seawater and a relatively low environmental impact.
