FURTHER INFORMATION:
Cascabel is located in northwestern Ecuador in an under-explored northern section of the Andean Copper Belt, 60 km northeast of the undeveloped inferred resource of 982 million tons at 0.89% Cu Llurimaga (formerly Junin) copper project2 (Figure 1).

A maiden Mineral Resource Estimate (MRE) for the Alpala deposit, estimated from the initial 53,616m of drilling, was announced on January 3, 2018 (see Cornerstone news release 18-01 on that date) and the corresponding Technical Report prepared by SRK Exploration Services Ltd. and qualified persons James Gilbertson, Martin Pittuck, and John Willis in compliance with National Instrument 43-101 was filed at www.sedar.com on February 16, 2018 (http://www.cornerstoneresources.com/i/pdf/AlpalaMRE_0218.pdf), and indicates resources of: 430Mt @ 0.8% CuEq Indicated and 650Mt @ 0.6% CuEq Inferred (3.4 Mt CuEq Indicated 4.0 Mt CuEq Inferred) at 0.3% CuEq cut off, for a metal inventory of 2.3 Mt Cu and 6.0 Moz Au Indicated and 2.9 Mt Cu and 6.3 Moz Au Inferred, including a high-grade core of 70Mt @ 1.8% CuEq Indicated (1.2Mt CuEq) and 50Mt @ 1.8% CuEq Inferred (0.8 Mt CuEq) at a 1.1% CuEq cut off. A further 50 Mt @ 1.0% CuEq Indicated (1.0 Mt CuEq) and 50 Mt @ 1.0% CuEq Inferred (1.0 Mt CuEq) is added to the high grade core if a 0.9% CuEq cut off is used, giving a high grade core of 220 Mt at a weighted average grade of 1.44% CuEq.

A further 80,538m of drilling has been completed since development of the maiden MRE (Figure 2), and major resource growth is expected in a revised MRE. JV partner and project operator SolGold is now aiming to expand and upgrade the resource, with infill and extension drilling at Alpala Central expected to expand the high-grade core as well as increase the overall resource tonnage.

Exceptional assay results from recent infill and extension drilling at Alpala Central are revealing a more robust high-grade core than estimated in the December 2017 MRE. This recent drilling shows that early stage diorite and quartz diorite intrusions, rich in copper and gold, are far more continuous than previously modeled.

Drill hole assays have been received for 111,010m of a total 134,155m on the project. Approximately 11,300m of drilling has assays pending, with 11800m accounted for as non-assayed top holes.

Highlights of assay results expected to add to the existing MRE at Alpala are tabulated in the below table.

About the Cascabel Joint Venture with SolGold:
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 is funding 100% of the exploration at Cascabel and is the operator of the project. SolGold shall receive 90% of Cornerstone's distribution of earnings or dividends from ENSA to which Cornerstone would otherwise be entitled until such time as the amounts so received equal the aggregate amount of expenditures incurred by SolGold that would have otherwise been payable by Cornerstone, plus interest thereon from the dates such expenditures were incurred at a rate per annum equal to LIBOR plus 2 per cent until such time as SolGold is fully reimbursed.

Logging, sampling, assaying and reporting
Holes referred to in this release were or are being drilled using HTW, NTW, NQ and BQ core sizes (respectively 7.1, 5.6, 4.8 and 3.7 cm diameter). Geotechnical measurements such as core recovery, fracturing, rock quality designations (RQD's), specific gravity and photographic logging are performed systematically prior to assaying. The core is logged, magnetic susceptibility measured and key alteration minerals identified by experienced loggers and sometimes using an on-site portable spectrometer. Core is then sawed in half at the ENSA core logging facility, and half of the core is delivered by ENSA employees for preparation at ALS Minerals Laboratories (ALS) sample preparation facility in Quito. Core samples are prepared crushing to 70% passing 2 mm (10 mesh), splitting 250 g and pulverizing to 85% passing 75 microns (200 mesh) (ALS code CRU-31, SPL21 and PUL-32). Prepared samples are then shipped to ALS in Lima, Peru where samples are assayed for a multi-element suite (ALS code ME-MSP61, 1g split, 4-acid digestion, ICP-MS finish). Over limit results for Ag (> 100 g/t) and Cu, (> 1%) are systematically re-assayed (ALS code Ag-AA62, 4-acid digestion, AAS finish). Gold is assayed using a 30 g split, Fire Assay (FA) and AA finish (ALS code Au-AA23).

Quality assurance / Quality control (QA/QC)
The ALS Laboratory is a qualified assayer that performs and makes available internal assaying controls. Duplicates, certified blanks and standards are systematically used (1 control sample every 15-20 samples). Rejects, a 100 g pulp for each core sample and the remaining half-core are stored for future use and controls.

About Cornerstone:
Cornerstone Capital Resources Inc. is a mineral exploration company with a diversified portfolio of projects in Ecuador and Chile, including in the Cascabel gold-enriched copper porphyry joint venture in north west Ecuador.

Pending Plan of Arrangement:
TSXV approval is still pending in respect of the plan of arrangement to spinoff Cornerstone Exploration Inc., first announced on July 13, 2017. The plan of arrangement received shareholder approval in December 2017 and court approval in January 2018. The Company will put out an update promptly following TSXV approval.

Pursuant to the plan of arrangement, Cornerstone will spin off into a new company called Cornerstone Exploration Inc., all of Cornerstone's assets except for its interest in the Cascabel concession in Ecuador, shares of SolGold plc and the joint venture with Ecuadorian state mining company ENAMI EP. Cornerstone Exploration will own the drill ready Bella Maria, Shyri NW (Vetas Grandes) and Bramaderos properties in Ecuador, an option to own 100% of the drill ready Caņa Brava property in Ecuador, the applications for new properties in Ecuador made by Cornerstone subsidiary La Plata Minerales S.A., the Miocene property in Chile, and Cornerstone's generative exploration databases for Ecuador and Chile. Cornerstone will be re-named Cascabel Gold & Copper Inc.
