Bramaderos



Primary Target
Copper-Gold Porphyry

Location
The 4,949 Hectares Bramaderos concession is located in Loja province, some 130 km (2 hours drive) from the Loja provincial capital city. Easy access is provided by the PanAmerican Highway crossing the western part of the concession.

Property Information
On December 5, 2017, Cornerstone announced that its subsidiary, La Plata Minerales S.A. ("Plamin"), had been awarded the "Bramaderos" concession in Ecuador following a public bidding process.

The Bramaderos property was sporadically explored during the periods 1970 to 1984, 2001 to 2002 and 2004 to 2007. Porphyry style gold-copper mineralization has been found mainly associated to quartz veins stockworks and breccias hosted by a cluster of potassic altered, northeast aligned, quartz-diorite poprhyries showing the typical porphyry alteration and mineralization patterns. An extensive, 5km by 1-2 km, gold and copper (+/- molybdenum) in-soil anomaly located in the central part of the property has been partially tested by trenching and diamond drilling. Several zones have not yet been followed up. A total of 888 rock and 1324 soil samples have been collected, 17 trenches dug and channel sampled, 31 line kilometers of magnetic and Induced Polarization (IP) surveys carried out, and a total of 10,426m of diamond drilling performed to test some of the anomalous areas.

Bramaderos has thepotential to host large-volume gold and copper mineralization. The available data will be fully assessed and a 3D mineralization model developed. Several near drill ready targets have been identified, and the property is available for joint venture.

Vetas Grandes


Primary Target
Gold - Silver - Copper

Location
The Vetas Grandes property is located in the Western Cordillera of the Andes in southern Ecuador, approximately 20 km southwest of Cuenca, the capital city of Azuay Province. The property covers a rugged area of some 300 km2, and lies at elevations ranging from 1,500 to 4,000 m above sea level. Access to the property is good via a series of paved and/or gravel roads, and numerous mule and foot paths.

Property Information
The Vetas Grandes property, originally acquired by Cornerstone in 2005, is an early stage exploration project which encompasses the Vetas Grandes gold prospect. It is strategically located between the Quimsacocha epithermal gold-silver-copper project to the east, the Rio Blanco epithermal gold-silver project to the northwest and the Chaucha porphyry copper-molybdenum deposit to the west.

The Vetas Grandes property straddles the Gañarin Belt, a 50 km-long regional feature which contains volcanic centres and associated high-level intrusions, and which is highly prospective for hosting epithermal gold - silver ± copper and porphyry copper - gold ± molybdenum deposits.

Highlights of the prospect is provided below:

Vetas Grandes
  • Multiple, east-northeast trending low sulphidation epithermal quartz veins and vein breccias measuring from 1.0 to 7.0 m in width within a zone at least 2 km long and 1.5 km wide
  • Mineralized veins containing gold and silver are exposed over a vertical relief of 300 m with the highest gold values localized at vein intersections and where veins outcrop around the 3,220 m elevation
  • Channel sampling across surface outcrops have returned 53.4 g/t gold and 641 g/t silver over 3.4 m
  • Drill ready - permits required to carry out Phase 1 drill program expected to be received Q1-Q2 2013

Cornerstone has been exploring in Ecuador since 2005 through its wholly-owned subsidiary, Cornerstone Ecuador S.A. Currently the Company has a portfolio of projects in Ecuador covering which are targeting epithermal gold-silver and porphyry copper-gold deposits.

An important part of the future valuation of Cornerstone derives from its interest in the Cascabel copper gold project in northern Ecuador, where drilling is ongoing and where eight high‐priority porphyry centres are now recognized within the project, and a total of ten porphyry targets identified to date in the Cascabel cluster. Significant copper-gold surface exploration results from rock have been obtained at the Aguiņaga and Trivino targets during the last few months. See NR-16-01 dated February 2, 2016 -Cascabel Exploration Update on Holes 13-16 (see link on Cascabel page), and also NR 15-23 dated October 20, 2015 - Cornerstone announces longest and highest grade intercepts to date in Hole 12 at Cascabel Project - 1312m @ 0.67% Copper, and 0.63 g/t Gold, for 1.05% CuEq (see link on Cascabel page).

Exploraciones Novomining S.A. ("ENSA"), an Ecuadorean company owned by SolGold Plc and Cornerstone, holds 100% of the Cascabel concession. Subject to the satisfaction of certain conditions, including SolGold's fully funding the project through to feasibility, SolGold Plc will own 85% of the equity of ENSA and Cornerstone will own the remaining 15% of ENSA. SolGold Plc is funding 100% of the exploration at Cascabel and is the operator of the project.

Cascabel is located in north-western Ecuador in an under-explored northern section of the richly endowed Andean Copper Belt, 60 km northeast of the undeveloped inferred resource of 982 million tons at 0.89% Cu Junin copper project (0.4% Cu cut-off grade; Micon International Co. Ltd. Technical Report for Ascendant Exploration SA, August 20, 2004, pages 28 & 29). Mineralization identified at the Junin copper project is not necessarily indicative of the mineralization on the Cascabel Property.

SolGold has announced it is planning a resource statement at Alpala, the most advanced target at Cascabel, during 2017, in addition to drill testing the other key targets at Aguinaga, Trivino, Tandayama America and Chinambicito in the Cascabel concession. SolGold has reported it is also planning further metallurgical testing, and completion of early stage mine and plant design and a scoping study (which may or may not be the equivalent of a NI 43-101 preliminary economic assessment) for an economic development at Cascabel. SolGold is investigating both high tonnage / low grade open cut and high grade / low tonnage underground developments as a block caving operation.

The Company has two wholly-owned exploration projects located in southern Ecuador, the Bella Maria, and Shyri (Vetas Grandes) projects, as well as one property, Caņa Brava, in which it has the right to earn 100%. The Shyri project has received the majority of work with approximately $13 million spent on exploration since 2005. Shyri encompasses the Vetas Grandes gold prospect and is strategically located west of the Loma Larga (formerly called Quimsacocha) high-sulphidation epithermal gold-silver-copper deposit, south of the Rio Blanco low-sulphidation gold-silver deposit and southeast of the Chaucha porphyry copper-molybdenum deposit. On all three projects, the Company has identified sizeable altered and mineralized zones which offer good potential for new discoveries. The Company has also received a concession in January 2017 called Bramaderos, in Loja Province (please see Bramaderos Property page).

Bella Maria

Primary Target
Gold

Location
The 10.4 km2 Bella Maria property is located approximately 50 km southeast of the city of Machala in southwestern Ecuador.

Property Information
The property is underlain by a series of granodiorites and quartz porphyries that intrude metamorphic rocks. Previous workers identified two zones of significant gold mineralization, approximately 2 km apart. One zone, in the south-central portion of the property, consists of a silica-sulphide breccia that has returned assays averaging 4.5 g/t Au over 40 m from continuous rock chip sampling, including 10.8 g/t Au over 16 m. The second zone occurs 2 km to the northwest and consists of stockwork veins from which grab samples assayed up to 10.8 g/t Au and chip samples returned assays up to 0.54 g/t Au over 6 m. The two zones are separated by an area of thick vegetation and poor exposure with many unexplained geochemical anomalies. Data on the property are being compiled in preparation for initiating further exploration.

This property is within the area of interest defined under the terms of the agreement between Cornerstone Ecuador S.A. and Sierra Minera (Sierramin) S.A. announced February 25, 2005. Cornerstone has subsequently earned 100% interest in the property and is actively seeking to joint venture this project.

Cascabel



Primary Target
Copper-Gold Porphyry

Partner
SolGold Plc (AIM code: SOLG)

Location
The Cascabel property is located in Imbabura Province in northern Ecuador, approximately 120 km north of Ecuador's capital city, Quito, and 20 km south of the Colombian border. The property covers an area of 50 km2 and lies at elevations ranging from approximately 750 to 2,100 m above sea level. Access is very good via a paved road from the coastal city of San Lorenzo to the provincial capital of Ibarra, and secondary gravel roads to the central part of the property.

Project Operator
SolGold Plc

Property Information
Exploraciones Novomining S.A. ("ENSA"), an Ecuadorean company owned by SolGold Plc and Cornerstone, holds 100% of the Cascabel concession. Subject to the satisfaction of certain conditions, including SolGold's fully funding the project through to feasibility, SolGold Plc will own 85% of the equity of ENSA and Cornerstone will own the remaining 15% of ENSA. SolGold Plc is funding 100% of the exploration at Cascabel and is the operator of the project.

Cascabel is an early stage copper-gold porphyry project located within the Western Cordillera of the Andes, which hosts numerous world class copper-gold deposits in Chile and northwards through Peru, Ecuador and Colombia. Large undeveloped deposits in the Cascabel region include the Llurimagua (formerly Junin) porphyry copper-molybdenum deposit 65 km. to the southwest (undeveloped National Instrument 43-101 compliant inferred resource of 982 Mt @ 0.89% Cu, 0.04% Mo and 1.9 g/t Ag), and the La Colosa porphyry gold deposit in neighbouring Colombia.

In August 2013 the Ecuadorean Ministry of Environment granted an environmental license for advanced exploration (including drilling). The drilling that began in September 2013 and is ongoing (18 holes as of August 2016) indicates the discovery of a large gold-enriched copper porphyry system. Several holes have intersected kilometric lengths of > 1% Cu equivalent (CuEq*), with higher included intercepts: Hole 5 (the Discovery Hole) intersected 1306m (from 24m) grading 0.62% Cu and 0.54 g/t Au (1.10% CuEq); Hole 9 intersected 1,271m (from 430m) @ 0.59% Cu and 0.77 g/t Au (1.28% CuEq; true width ~485m); Hole 12 intersected 1312m (from 128m) @ 0.67% Cu and 0.63 g/t Au (1.23% CuEq); and Hole 16 intersected 1145.6 m (from 516m) @0.63% Cu, 0.78 g/t Au (1.32% CuEq). Several other holes have similar CuEq grades over >500m. Approximately 60% of core intercepts for high angle holes are true widths.

SolGold has announced it is planning a resource statement at Alpala, the most advanced target at Cascabel, during 2016, in addition to drill testing the other key targets at Aguinaga, Trivino, Alpala NW, Hematite Hill, Alpala SE, Cristal, Tandayama America, Moran, and Chinambicito within the Cascabel concession. SolGold has also announced that by the end of 2016 it is planning further metallurgical testing, and completion of early stage mine and plant design and a scoping study (which may or may not be the approximate equivalent of a preliminary economic assessment as defined under Canada's National Instrument 43-101) for an economic development at Cascabel. SolGold has reported it is investigating both high tonnage / low grade open cut and high grade / low tonnage underground developments as a block caving operation.

The Cascabel property is underlain by Upper Cretaceous sedimentary rocks which are overlain by Oligocene to Miocene andesitic flows and breccias. These units are intruded by Miocene age granodiorite and diorite batholiths and stocks. Major regional tectonic structures in the area strike northeast. One such structure, the Apuela regional fault, transects the southeast part of the Cascabel property. Several mineral prospects which are hosted in the same geological belt, have been identified in the Cascabel district including the Chical (Au-Ag) and Rio Amarillo (Au-Ag-Cu) epithermal prospects located 12 km to the northwest and 12 km to the south of the property respectively. Cascabel is located upstream from an extensive alluvial gold district, Playa de Oro, located 50 km to the west.

Monterrey/Caņa Brava

Primary Target
Gold

Location
The Monterrey Property covers an area of approximately 20 km2 located in southern Ecuador. The near-by Cana Brava property has been optioned from a local prospector and is 11.5 km2 in area.

Property Information
The property hosts gold mineralization associated with altered and brecciated intrusive rocks cutting meta-volcanics and meta-sediments. Recent channel sampling by Sierramin returned assays of 7.3 g/t Au over 1.1 m. Widespread stream, silt and heavy mineral anomalies occur across both project areas. Chip samples from quartz veins and associated stockwork veins in argillically altered volcanics assayed up to 10.5 g/t Au and 30.5 g/t Ag over 0.5 m, 4.5 g/t Au and 34 g/t Ag over 0.7 m and 4.1 g/t Au and 110 g/t Ag over 1.0 m. Also, several new prospects with anomalous gold and silver values were discovered.

Cana Brava hosts a large argillic lithocap which encompasses smaller areas of high sulphidation, advanced argillic alteration which may sit above a copper porphyry system at depth. Several surface samples carrying values between 1000 and 5000 ppb gold are related to altered rhyolite porphyry dykes and bodies

Cornerstone is actively seeking to joint venture this project.

  • Work on the Shyri concessions, collectively over 450 km2 in area, indicates potential for low and high sulphidation precious metal deposits in several target areas. The Shyri concessions straddle the Gañarin Belt and are immediately adjacent to IAMGold Corporation's Quimsacocha project. The Gañarin Belt is a 50 km long feature with several volcanic centers, related intrusives and numerous epithermal gold-silver prospects. Quimsacocha is the most advanced project in the Gañarin Belt. IAMGOLD first announced significant drill intersections at Quimsacocha in December 2004 and in September 2006 they reported an indicated resource of 3.4 million ounces of gold in the deposit (IAMGold Corporation press release, 27 September 2006).


    Vetas Grandes

    Primary Target
    Gold

    Location
    The Vetas Grandes project covers 107.75 km2 located in the central portion of the Shyri concessions, immediately southwest and contiguous with IAMGold's Quimsacocha project.

    Property Information
    This project has two main prospects; the Vetas Grandes prospect and the Tasqui prospect.

    The Vetas Grandes prospect has several large, 3.0 m to 7.0 m wide veins and quartz vein/vein breccia/stockwork form a swarm striking east-northeast over a distance of 1.4 km. The veins have elevated mercury (Hg), selenium (Se) and tellurium (Te) and display diagnostic textures indicative of a high level epithermal system with bonanza grades focused at the 3200 m elevation. Extensive surface sampling and geophysical surveys (magnetic and IP) have been completed over the prospect.

    The Tasqui Prospect consists of a 2.0 to 7.0 m wide magmatic-hydrothermal vein breccia which has been traced over a distance of 440 m. This was originally discovered by float prospecting that has just recently been traced to outcrop.
