Atico Mining drills 18.5 m of 10.3% Cu at El Roble

Nov 1, 2012 - News Release

Atico Mining Corp.'s underground drilling at the El Roble mine continues to intersect and extend to depth high-grade massive sulphide and gold mineralization below the 2,000-metre level, the lowest production level at the mine at 250 metres below surface.

Atico reports the results of 11 new diamond core holes drilled, including five production holes drilled by Minera El Roble, current operator of the El Roble mine, and independently sampled and assayed by Atico. Atico's drilling extends the known mineralization 230 metres below the 2,000-metre level and along 300 metres of strike.

Fernando E. Ganoza, chief executive officer of Atico, commented: "The company is extremely pleased with the results of the most recent underground drilling at El Roble project. We have significantly increased the potential for additional high-grade resources at El Roble mine by vertically extending the known mineralized zone, which remains open at depth. Testing the extent of mineralization along strike and at depth will continue, as well as defining the potential of mineralized lenses intersected below level 2000."

Highlights of the drilling include:

ATDHR-12 -- 18.20 metres of 10.30 per cent copper (Cu), 2.10 grams per tonne (g/t) gold (Au) and 6.59 g/t silver (Ag);

MEI-193 -- 6.48 metres of 4.90 per cent Cu, 4.57 g/t Au and 34.78 g/t Ag;

MEI-192 -- 4.22 metres of 1.15 per cent Cu, 8.14 g/t Au and 38.60 g/t Ag;

ATDHR-13 -- 0.50 metre of 2.40 per cent Cu, 14.15 g/t Au and 143.00 g/t Ag.

Underground drilling program

The continuing underground drill program aims to add additional resources of high-grade copper-gold massive sulphide bodies lateral to and below the existing mine workings. Atico's first four drill holes of this program (see news release dated July 12, 2012) proved the existence of mineralization 100 metres below the 2,000-metre level. The results of the latest drill holes indicate that massive sulphide mineralization extends at least 230 metres below level 2000, where ATDHR-13 intersected 0.50 metre of 2.4 per cent copper and 14.50 g/t gold. Intercepts higher in the hole extend the mineralization from ATHDR-01 and ATHDR-04 by 150 metres to the southeast (see news release dated July 12, 2012).

Assays of the footwall and hangingwall to the massive sulphide mineralization in previously reported drill holes along with ATDHR-12 and ATDHR-13 show that gold mineralization extends several metres above and below the mineralization into the host black chert unit. ATDHR-05 (see news release dated Sept. 24, 2012) intersected 16.60 metres of 1.75 g/t gold from 62.40 metres and ATDHR-13 reported 7.25 metres of 2.19 g/t gold from 58.15 metres.

Current drill intercepts confirm the presence of massive mound sulphides, feeder vein stockworks and multiphase massive sulphide breccias. The geometry and zoning of the existing mineralization coupled with the new intercepts imply that only half of the massive sulphide mineralization, about 1.5 million tonnes, have been found and mined to date. This is consistent with the indication from recent drilling of the potential for significant additional tonnage below the current mine workings.

Minera El Roble drilled 12 short exploratory holes ahead of production from the 2,000 metre level. The latest holes, which have variable azimuths and declinations and recoveries particularly in broken ground, are listed in the associated table. Recoveries in massive sulphide sections vary from 50 to 60 per cent. Minera El Roble holes, sampled and assayed by Atico, intersected massive sulphide mineralization grading from 6.37 per cent copper over one metre in MEI-198 to 6.48 metres of 4.90 per cent copper in MEI 193, indicating continuity of mineralization from the 2,000-metre level to those drilled by Atico.

All reported drill intercepts represent downhole intercepts and not true widths. Owing to the pod-like nature of the massive sulphide mineralization no true width estimates of the mineralization can be made.

El Roble property

El Roble property hosts an operating underground copper and gold mine with nominal capacity of 400 tonnes per day. Over the past 22 years the mine has processed 1.5 million tonnes of mineralized material at an average grade of 2.5 per cent copper and estimated gold grade of 2.5 g/t. Copper and gold mineralization at El Roble property occurs as volcanogenic massive sulphide (VMS) lenses. Exploration over the past two years has defined a productive contact and an enclosing package of host rocks extending for a distance of 10 kilometres across the property. This entire strike length is marked by VMS mineralization occurrence indicators.

Atico has a two-year option agreement to acquire 90 per cent of Minera El Roble, current operator of El Roble mine, for staged payments of $2.25-million (U.S.) over two years (all staged payments have been made as of July 28, 2012) and a lump sum payment of $14-million (U.S.) upon exercise of the option. The option can be exercised at any time during the two-year option period upon payment of the $14-million (U.S.). Atico has the right to extend the option period by one year, by giving notice to Minera El Roble 21 days prior to the expiration of the initial option term (Jan. 28, 2013) and paying an additional $1.2-million (U.S.).

Quality assurance and quality control

Following detailed geological and geotechnical logging, drill core samples are split on-site with a diamond saw by Atico personnel. The seven to 10 kilograms per metre of samples are submitted to the ALS Chemex Laboratory in Medellin where they are dried, crushed and pulverized. After preparation the samples are sent to ALS Chemex in Lima and assayed. The remaining half core is retained on-site for verification and reference purposes. All gold assays were obtained by standard 50-gram fire assay with AA finish. All copper and silver assays reported were obtained by aqua regia sample dissolution of the sample followed by ICP analysis. The QA/QC (quality assurance/quality control) program includes the blind insertion of certified reference standards as well as assay blanks and duplicates at a frequency of approximately one per 15 samples.

Atico Mining (ATY-V) is focused on building a leading mid-tier, high margin Latin American-based copper-gold producer. Its principal asset is an option to acquire 90% of the El Roble project, a high-grade, producing VMS mine in Colombia that has processed 1.5 million tonnes at an average of 2.5% Cu and 2.5 g/t Au over the past
20 years. Atico is led by Fernando Ganoza, CEO, and is associated with the Fortuna Silver (FVI-T | SPECULATIVE BUY - Canaccord/Genuity) management group.
