MOUNT PEARL, NEWFOUNDLAND--(Marketwire - Oct. 3, 2012) - Cornerstone Capital Resources Inc. ("Cornerstone") (News - Market indicators) (FRANKFURT:GWN) (BERLIN:GWN) (OTCBB:CTNXF) today announced results from prospecting work carried out on its wholly-owned La Encrucijada project located in south central Ecuador.


  • Re-assessment of the Marcoloma and Alumbre prospects confirm the potential to host significant epithermal high-sulphidation (HS) gold-silver mineralization and structurally controlled intermediate sulphidation (IS) gold-silver and base metal mineralization
  • A new epithermal HS alteration zone identified at Potrerillos
  • Size of the Alumbre gold-silver prospect extended
  • Ridge and spurs soil sampling on the Alumbre sector on the northern part of the property defines a gold-in-soil anomaly measuring 1,000 metres (m) by 500 m that is open in one direction. A second 500 m by 400 m gold anomalous area defined to the south

Brooke Macdonald, President of Cornerstone, said "We are very pleased with the progress made so far at La Encrucijada. We have confirmed results by previous companies and new exploration results show that the property has potential to host significant shallow epithermal gold-silver mineralization and porphyry gold-copper style mineralization at depth. Following our prospect generator business model, we are actively looking for a partner to jointly explore this property".

Background Information

During 2011, Cornerstone announced the acquisition of the Ecuadorian company Santa Barbara Copper and Gold S.A. (SBCG) and its Cascabel and La Encrucijada projects. A description of the projects and exploration results were provided on February 11, 2011 (NR 11-06) and March 29, 2011 (NR 11-14). An authorization to resume exploration activities on the La Encrucijada project was granted by the Ministry of Non-Renewable Natural Resources on June 08, 2011 and an environmental license was issued by the Ministry of Environment on July 28, 2011.

La Encrucijada Property

La Encrucijada is located in south-central Ecuador in Loja province, 100 km south of the city of Cuenca and near the community of Saraguro. The property is situated in the Ecuadorian Andes on the east side of the Cordillera Occidental at elevations ranging from 1,200 to 3,100 m above sea level. Access is good via the paved Pan American Highway south from Cuenca and secondary gravel roads into the property. The climate is temperate, with grasslands at high altitude.

Regional Geology

The project area is dominated by mafic and felsic volcanic flows, tuffs and associated sediments of the Late Oligocene Sacapalca Group, the Late Eocene Saraguro Group and the Miocene La Paz Formation crystal tuff. These are intruded by diorite stocks rich in plagioclase, hornblende and magnetite and rhyolite stocks, probably of Late Miocene age. The property lies between two major northeast (NE) trending regional faults. The Catamayo Fault cuts the area to the southeast (SE) of the property and the Giron Fault is located approximately 10 km to the northwest (NW). Cross cutting transverse faults developed within this structural trend often control the emplacement of intrusions and development of alteration and mineralization.

Copper-gold porphyry and gold-silver epithermal prospects are located along this major NE structural trend that contains the La Encrucijada prospect. The Fierro Urco, Caña Brava, Monterrey prospects cluster located 25 to 30 km southwest (SW) of La Encrucijada consists of HS gold-silver mineralization developed in quartz alunite lithocaps associated with gold-copper enriched porphyry intrusions. Low sulphidation gold-silver quartz veins occur at Monterrey near the Giron Fault, trending north-south in this area. The Cañicapa prospect located about 10 km to the south of La Encrucijada is a HS epithermal system with approximately 200 ppb gold and 200 ppm Mo developed in vuggy silica. A steam heated quartz alunite lithocap overlies the zone and there are indications of a porphyry stock at deeper levels. Goldfields Ltd completed 20 drill holes in the mid 90's to evaluate this HS occurrence. The Celen prospect, located south of Cañicapa, is a gold prospect in massive silica with abundant sulphides. The Mozo prospect, situated 20 km NE of La Encrucijada, is a HS epithermal system which was previously drilled during the period by Newmont Mining Corporation (1994-97), Iamgold Corporation ("Iamgold") (2004-06) and Channel Resources Ltd (2007) to evaluate the gold potential.

Property History

Free gold from the Alumbre River was first reported by Billiton plc (now BHP Billiton Ltd) in 1996 and the area was followed up with sediment and soil sample surveys. Iamgold initiated survey work in 2003 which included geological mapping and rock sampling. Anomalous gold values of 0.122 to 1.40 g/t Au were reported in rocks.

SBCG began exploration in 2007 and carried out a soil survey, some geological mapping and rock sampling at the prospects. Cornerstone acquired the concessions in 2011. Geological mapping and prospecting data were compiled from previous work and initial work confirmed the reported gold mineralization and grades during field campaigns carried out during 2011 and 2012.

Prospecting Program

Geological crews carried out prospecting work over the entire project area (5 concessions totaling 80.85 km²) to verify the earlier exploration results and to extend the reconnaissance geological mapping and sampling program over the balance of the project area that had not been previously explored. Fifty-eight (58) representative rock chip samples and sixty-six (66) stream sediment samples were collected during the prospecting program. A second program was carried out on the concessions in 2012. This included follow-up of the Alumbre prospect area on the north part of the concession. One hundred thirty one (131) representative rock chip and rock channel samples and 165 ridge top soil samples were collected.

Property Geology and Mineralization

The property is underlain by rhyolite, dacite and andesite lapilli and crystal tuff and volcanic sediments, which are intruded by a diorite porphyry. The project area lies between two major regional faults, Giron and Catamayo Faults that produced a dextral movement. The parallel Rio Leon Fault occurs on the NW edge of the property. NW-SE trending transverse faults are developed within the project area which control the emplacement of diorite intrusions and the associated development of alteration and mineralization. Porosity of the host rock is also an important control on alteration and mineralization.

Prospecting and geological mapping have identified three gold-silver mineralized zones to date.

  • Alumbre:  Initial rock sampling was carried out during 2011 and more detailed channel sampling in 2012 over the Alumbre prospect. Consistently elevated gold occurs in outcrop exposed in the Alumbre River channel over a 135 m interval. The 59 rock samples are mostly sawed 2 m-long channel samples. Gold values range from 0.10 to 2.65 g/t Au (mean value of 0.68 g/t Au), including a section with 0.97 g/t Au and 1.61 g/t Ag over 30 m. Arsenic is highly anomalous, generally ranging from 1,000 ppm to 3,000 ppm, with a strong correlation with gold. Values for zinc, lead, antimony, molybdenum and copper are elevated with values up to 2,400 ppm Zn, 400 ppm Pb, 28.2 ppm Sb, 3.4 ppm Mo and 83 ppm Cu.

    Alumbre is a NW-SE trending structurally controlled gold zone hosted mainly by andesite flows and tuffs and a diorite breccia exposed on the SE end of the zone. Alteration consists of pervasive chlorite and illite alteration +/- sericite, smectite and epidote with variable silicification. Fine disseminated pyrite is ubiquitous throughout the mineralized zone and is generally less than 5%. Trace chalcopyrite occurs locally. Quartz-calcite (+/- barite) veinlets are common.

    Faults and fracture zones trend north to NE with a moderate to steep dip (50 to 70 degrees) to the west and may be related to transverse faulting developed between the major northeast trending regional faults. Bedding in andesite tuff is variable but generally dips at a shallow angle to the south.

    A large area of colluvium covers most of the bedrock north of the river. Four outcrops of andesite tuff, located up to 35 m north of the river, returned anomalous gold (0.73, 0.63, 0.98, 0.88 g/t Au) indicating the mineralized zone may extend under cover.
  • Marcoloma and Potrerillos: These two prospects are located in the central part of the property and show advanced argillic alteration zones developed in acid pyroclastic volcanic rocks. At Marcoloma, quartz - alunite - oxidized rib-like features are exposed in quartz crystal lithic lapilli tuff in outcrop trending NW-SE. The best gold values (1.12, 1.44, 2.08, 3.38 and 5.13 g/t Au) are associated with strong silicification, barite and minor pyrite. Twenty three (23) samples grade greater than 30 g/t Ag at the Marcoloma prospect. The Potrerillos zone is located 1 km east of Marcoloma with similar alteration. Very limited work was carried out on this prospect. Two 500 m by 500 m areas of vuggy silica blocks are located adjacent to these prospects and further work is required to locate the source.

Stream and Soil Sampling Survey

Sixty four (64) stream sediment samples were collected over the entire property. Assay results were integrated into Cornerstone's regional geochemical database. Stream sediments from the same locations were pan concentrated to verify the presence, size and shape of gold grains. Anomalous gold values occur in stream silt draining the Alumbre prospect on the north part of the property and also the central area with the two advanced argillic alteration zones of Marcoloma and Potrerillos. Arsenic is elevated (up to 260 ppm As) and correlate with the anomalous gold. Lead is strongly anomalous throughout the area with a maximum value of 782 ppm Pb.

Ridge top soil lines (165 samples) completed on the north part of the property in the Alumbre sector has defined two gold anomalies. The northern anomaly is defined over an area measuring 500 m by 1,000 m and is open to the SE. The anomalous gold values (9 samples) range from 50 ppb to 1,196 ppb Au and correlate with elevated copper, lead, zinc, silver, molybdenum and arsenic. Geological mapping shows it is underlain by colluvium with limited outcrop exposure. There is no survey work between the gold-in-soil anomaly and the Alumbre prospect located 1 km to the south.

The second gold anomaly is located 800 m west of the Alumbre prospect and consists of a cluster of elevated gold-in-soil values from 33 ppb to 97 ppb Au in an area measuring 500 m by 400 m. These soil anomalies occur in an area of strong topographic relief.

Results from the soil survey over the Marcoloma prospect define a northwest-striking gold and silver soil anomaly which is more than 1 km in length, and is open to the southeast. Assay results show strong correlation for gold, silver and base metals with the known mineralization exposed at surface. The soil values (with the exception of lead) are nearly an order of magnitude higher in the Alumbre sector than at Marcoloma.

Regional airborne magnetic survey

In 2000, Canadian-based Sial Geosciences Inc. on behalf of the British Geological Survey flew a regional magnetic survey with 1 km line spacing. The survey successfully identified regional structures and large scale geological features.

Strong NE trending lineaments sub-parallel to the Catamayo Fault are identified north and south of the La Encrucijada property. A distinct positive magnetic anomaly in the center of the concession correlates with mineralization and alteration at Marcoloma and Potrerillos. This magnetic high may reflect the presence of a buried porphyry intrusion.

Results and discussion

Recent prospecting work by Cornerstone confirms results from previous property owners and provides technical information over the entire property. Although still preliminary, this work allows for a better understanding of the alteration and mineralization processes and their controls. The work also increased the size of the Alumbre prospect and discovered the new Potrerillos HS alteration zone. 

Three altered and mineralized zones are present on the property. Many anomalous float samples, stream sediment anomalies and soil anomalies (for precious and base metals, epithermal pathfinders) still have to be followed up and could, eventually, lead to the discovery of new mineralized zones.

An advanced argillic HS alteration zone lies in the central part of the property. It is more than 2 km² in size and of irregular shape. It is host of the Marcoloma prospect and the newly discovered Potrerillos prospect.

Field evidences indicate that the HS alteration system may lie on top of a porphyry copper-gold system at depth.
