Indico Announces Positive Results From Supergene Zone at Ocana
Porphyry Copper Mineralisation Still Open in Three
Directions
VANCOUVER, BRITISH COLUMBIA--(Marketwired - Apr 11, 2014) -
Indico Resources Ltd. ("Indico" or the "Company") (TSX-VENTURE:IDI)
is pleased to announce assay results for eight additional drill
holes of the Phase 3 programme at Ocaña. Twenty-four holes are now
completed, totalling 2262 metres. Sequential copper leach results
for these eight holes are tabulated below (Table 1), with the
results indicative of how amenable the mineralization is to
heap-leach processing. Three of these holes tested the outer
extents of deep chalcocite mineralization in the southeast portion
of the prospect. The holes intersected wide intervals of mainly
chalcocite mineralization (see Figure 1) and all ended in primary
(hypogene) mineralization above 0.1% Cu, most above 0.2% Cu (Table
2) demonstrating that the sulphide mineralisation continues to the
north, south and east.
President and CEO, Bob Baxter, stated: "The recoveries, grades
and thicknesses are consistent with our expectations at this stage
of the drilling program. We are on track to deliver a PEA on the
potential for an SX-EW project at Ocaña by early Q3 2014. The
benefits of an SX-EW project being that copper metal can be
produced on site as cathodes with up to 99.9% or higher copper
content, which results in lower cost per pound of copper for
transportation to market. This, together with other positive
aspects of our infrastructure, including availability of power and
water within a 10-15 km radius, is very positive. We expect that,
based on a positive result of our PEA, we will go on to complete a
feasibility study of the oxide project by Q1 2015 and make a
decision on the project development at that time."
The Ocaña Property consists of 22 concessions covering 110 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
less than 100 metres. A Hydracore 4000 man-portable drill rig is
being operated by Geotec S.A., and should be able to complete the
programme by early May, 2014. Currently 33 holes are planned,
totalling 3150 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. As well,
SGS Laboratories, under the direction of veteran metallurgist
Joseph Keane, will be contracted to perform the column leach tests
as the current programme wraps up.
The recent drilling completed along the southwest side of the
main ridge, where most holes intersected the bottom of the
supergene at greater than expected depths. The supergene blanket
extends under the alluvial gravel cover. One additional hole,
OCA13-24, was added to test the limits of the blanket 100m out in
the alluvial valley, and intersected 20 metres of mixed zone
supergene (copper oxides and secondary sulphides).

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 assay highlights from
current (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 extensive
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 of both regular assays and acid-soluble
copper analysis. 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).
Multi-elements were assayed using Acme's M300 package, which
includes 4-acid digestion and ICP-ES finish; samples with >0.5%
copper are reassayed using an atomic absorption (AAS) finish
(MA402). Lower detection limits are as follows: Cu >0.001%, Mo
>0.001%, Ag >0.5g/t. Sequential copper leach tests are done
by method LHSEQ, and acid consumption by method (GC850). Gold is
assayed by fire assay (FA430), in which fusion of a 30-gram aliquot
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.
