Indico Resources Ltd.: Additional Drill Results From Phase 2 Drilling Campaign, Ocana Porphyry Cu-Mo-Au Project
20.12.2012 | Marketwire
Best hypogene drill intersection to date:OCA010 with 300 metres of 0.70% CuEq
- including 57 metres of 1.53% Cu Eq
VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 12/20/12 -- Indico Resources Ltd. ("Indico" or the "Company") (TSX VENTURE: IDI)(OTCQX: IDIFF) is pleased to provide additional encouraging drill results from the Phase 2 drilling campaign at the Ocana Cu-Au-Mo porphyry in Arequipa Region, Southern Peru. In Phase 2, a total of 4733 metres were drilled in 19 holes; the additional significant assay results from holes received since the last news release are shown in Figure 1 and Table 1, and all significant intersections are listed in Table 2.
The northeastern-most hole drilled, OCA010, intersected the highest-grade primary (hypogene) mineralization yet encountered within the diorite breccia. This hole assayed 300 metres of 0.49% copper and 0.17 g/t gold, or 0.70% CuEq(i), and including 57 metres of 1.11% copper and 0.21 g/t gold. The hole ended at 300.5 metres within mineralization grading greater than 0.3% copper (Figure 2). To the south, within the diorite and diorite breccia, hole OCA011 intersected 103 metres of 0.53% copper, 0.28 g/t Au (0.81% CuEq) before entering dacite breccia, which returned 122 metres of 0.21% copper. Assays are pending for hole OCA014 drilled perpendicular to the southwest from the same platform. Holes to the west are similarly mineralized with significant gold grades accompanying the copper (Figure 3: OCA004 intersected 264 metres of 0.36% copper and 0.15 g/t gold (0.55% CuEq), including 39 metres of 0.69% copper and 0.20 g/t gold (0.94% Cu Eq).
A primary aim of the Phase 2 programme was testing the thickness and grade of sulphide and oxide supergene mineralization intersected by two holes in Phase 1. This supergene mineralization will be the initial focus for resource definition, as it is amenable to low-cost, acid heap-leaching, based on soluble copper tests on core sample pulps from two Phase 1 drill holes. The supergene target was successfully tested by six vertical holes along the crest of the southern ridge (see Figure 1) and expanded into the centre of the system by three angled holes and one vertical infill hole (OCA016). Results from holes OCA003, 7, 12, and 13 indicate that the supergene blanket is consistently approximately 50 metres thick, and consists of copper oxide and sulphate minerals near the top, grading down into dominantly chalcocite at the base, where it transitions sharply to hypogene chalcopyrite mineralization (Figures 2 - 4). In Table 1, intersections within the mixed zone should be amenable to acid heap leaching. The blanket dips to the west subparallel to the ridge crest, and has an east-west dimension of over 700 metres, with a width over 200 metres at the west end, increasing to 400 metres on the east end. Under the central part of the system the blanket averages about 30-45 metres thick and thins to the east as the slope steepens.

(i) Copper equivalent calculations represent the total metal value for each
metal, multiplied by the conversion factor, summed and expressed in
equivalent copper percentage. These results are exploration results only and
no allowance is made from recovery losses that may occur should mining
eventually result. These equivalent grades should not be interpreted as
actual grades since the conversion rations vary with the volatile prices of
Cu and Mo and the economic recoveries of Cu and Mo can vary significantly in
actual extraction and processing. However, it is the company's opinion that
elements considered here have a reasonable potential to be recovered. The
three-year, moving-average metal prices used for the purposes of the
equivalency calculations are copper $US3/pound, gold $US1500/ounce,
molybdenum $US15/pound and silver $US21/ounce.
(ii) Results preliminary pending QA/QC review of re-assayed intervals.
Assay results for holes OCA013 to OCA019 are pending.
Bob Baxter, President and CEO commented, "As the results of our Phase 2 program continue to deliver excellent results, not only do the supergene results to date look like they have the potential to support a mid-size SX-EW copper project, but we also see a higher-grade centre in the hypogene taking shape, which we will continue to follow-up in a future campaign."
Based on the successful Phase 2 results, Indico plans to continue with a Phase 3 program of about 30 short (100 metre) infill drill holes at about 100-metre spacing to further delineate the supergene blanket. This programme is expected to start in early 2013.

John Drobe, P.Geo., Indico's Chief Operations Officer and a qualified person as defined by National Instrument 43-101, has reviewed the scientific and technical information that forms the basis for this news release. Mr. Drobe is not independent of the Company as he is an officer and a shareholder.
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. Core was evenly split with a diamond saw, with one half collected for sample preparation and analysis, and the other half retained for future reference. Samples were collected on a 2.0m and 3.0m sample interval. 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. Multi-elements were assayed using Acme's 1E package which includes 4-acid digestion and ICP-ES finish; samples with greater than 1% copper are reassayed using an atomic asorption (AA) finish. Lower detection limits are as follows: Cu greater than 0.001%, Mo greater than 0.001%, Ag greater than 0.5g/t. 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.
The geochemical results were compiled and reviewed by John Drobe.
