Indico Announces Initial Results of Phase 3 Drill Programme at the
Ocana Copper Porphyry Project
VANCOUVER, BRITISH COLUMBIA--(Marketwired - Mar 3, 2014) -
Indico Resources Ltd. ("Indico" or the "Company") (TSX-VENTURE:IDI)
is pleased to announce the initial drill results for the Phase 3
programme at Ocaña, with thirteen holes completed to date,
totalling 1434 metres. Results for six of these holes are tabulated
below, including the results of sequential copper leach tests that
indicate how amenable the mineralization is to heap-leach
processing. These first six holes mainly tested the northern
extents of the supergene blanket, where it is thinner and eroded
through in places. Subsequently we have drilled thick intervals of
mainly chalcocite mineralization in the southeast corner and infill
holes along the main ridge crest.
President & CEO Bob Baxter commented, "We are pleased to
report the early results of our current work program. This program
started on the flanks of the northern extremities of the oxide and
enriched zone of mineralisation and confirms our understanding of
this mineralisation. The acid consumption and recovery data
generated from our analysis is also in keeping with our
expectations".
The Ocaña Property consists of 22 concessions covering 110.24
km2 and is located on the northwest extension of the Southern Peru
Porphyry Copper Belt, a trend defined in part by the Toquepala,
Quellaveco, Cuajone, and Cerro Verde Mines to the southeast. Most
recent exploration of the belt has resulted in discovery of the
Zafranal copper-porphyry deposit, located approximately 75 km to
the southeast of the Ocaña Property.
The current drill programme is primarily an infill programme to
define a horizontal layer of near surface, supergene
mineralization, and is designed to tighten the drill spacing to
100m and less. A Hydracore 4000 man-portable drill rig is being
operated by Geotec S.A., and should be able to complete the
programme by mid- to late April, 2014. Currently 32 holes are
planned, totalling 3050 metres, and comprising mostly short,
vertical holes to infill and further delimit near-surface,
flat-lying supergene mineralization. Indico has recently signed a
contract with Mining Plus Pty Ltd. to conduct a NI 43-101 compliant
maiden resource estimate for Ocaña upon completion of this drill
phase.

Note: Total Cu% is sum of acid, cyanide, and residual Cu
assays; Soluble Cu is the sum of acid and cyanide soluble assays;
Recovery% is the soluble copper divided by the total copper; Acid
consumption is kilograms of sulfuric acid per tonne of
material. |
Soluble copper and acid consumption tests from these and
previous results indicate the supergene mineralization should be
amenable to low-cost, SX/EW heap-leach processing. Figure 1 shows
the layout/density of the planned holes and highlights from this
(in black) and Phase 2 (in grey) drilling. Additional maps and
cross sections, as well as previous drill results, are available at
http://www.indicoresources.com/s/Ocana.asp.
To close the programme, four additional longer holes (400 metres
each) are planned to test the eastern limits of the larger hypogene
mineralization, bringing the total to 4650 metres.

Diamond Drilling and Sampling Procedures
The diamond drilling was completed using exclusively HQ core
size. Core recovery was estimated to be greater than 95% for any
given hole. Whole core was split in half with a manual core
splitter for intervals of brittle copper oxides, and the remainder
with a diamond saw. One half is collected for sample preparation
and analysis, and the other half retained for future reference.
Samples were collected on a 2.0m (leached, mixed and enriched
zones) and 3.0m (hypogene zone) sample intervals. Indico on-site
personnel rigorously mark, collect, and track samples which are
then security sealed and shipped to Acme, Lima, Peru for
preparation. Pulps are then forwarded to Acme's analytical lab in
Santiago, Chile.
Analytical accuracy and precision are monitored by the analysis
of reagent blanks, certified reference material, and duplicate
(coarse rejects and quarter core) samples. Indico inserts blind
certified reference material at regular intervals (1 in 20) into
the sample sequence by field personnel in order to independently
assess analytical accuracy. In addition, representative blind
duplicate samples are routinely forwarded to Acme for additional
quality control (1 in 20 coarse rejects, and 1 in 40 quarter core).
Quality control is further assured by the use of certified
reference material inserted 1 in 20 samples, including one standard
certified for acid-soluble copper analysis. Multi-elements were
assayed using Acme's 1E package which includes 4-acid digestion and
ICP-ES finish; samples with >0.5% copper are reassayed using an
atomic absorption (AAS) finish. Lower detection limits are as
follows: Cu >0.001%, Mo >0.001%, Ag >0.5g/t . Sequential
copper leach tests are done by method G904, and acid consumption by
method G909. Gold is assayed by fire assay, in which fusion of a
30-gram aliquote is followed by AA finish; with a lower detection
limit of 0.005 g/t. Acme has an 9001:2008 and 17025 International
Standard Organization rating.
