Pre-Feasibility Study Update - Alpala Project, Cascabel Concession, Ecuador
OTTAWA, April 08, 2021 (GLOBE NEWSWIRE) -- Cornerstone Capital Resources Inc. (“Cornerstone” or “the Company”) (TSXV:CGP) (Frankfurt:GWN1) (Berlin:GWN1) (OTC:CTNXF) is pleased to announce the following update on the status of the Pre-feasibility Study (PFS) on the Alpala Project at its Cascabel copper-gold porphyry joint venture project in northern Ecuador (the “Project”) in which Cornerstone has a 15% interest1 financed through to completion of a feasibility study plus 7.5% of the shares of joint venture partner and Project operator SolGold Plc, for a total direct and indirect interest in Cascabel of 21.4%. The Alpala Project Team and the Project Committee, chaired by Interim CEO Keith Marshall, are making good progress studying potential Alpala mine plans while addressing a number of mine development and metallurgical enhancements as well as potential upsides, and are continuing to target the release of the PFS in late 2021. The Alpala deposit comprises 2,663 Mt at 0.53% CuEq in the Measured plus Indicated categories and contained metal content of 9.9 Mt Cu, 21.7 Moz Au and 92.2 Moz Ag.2 The deposit measures approximately 900m in height and 500m diameter. Given the size and geometry of the deposit, the Company is quite optimistic that the PFS will demonstrate that it is amenable to underground caving mining methods. The Company is confident that this revised approach being studied from that which was previously considered is much more beneficial for Cornerstone and SolGold and will deliver significant shareholder value. SolGold is currently expanding its team of experienced technical staff, with the first, Ms. Lisa Park, Head of Metallurgy, having officially joined in recent days. Key considerations that suggest the superiority of the revised approach currently being studied for the development of the Project include: much earlier access to the resource with shortest time to potential first production;a more selective mining approach, without sterilizing the remaining resource, reducing dilution without compromising metal extraction;optimal size and orientation of an underground footprint with the potential for two extraction levels to minimize dilution and upfront development Capex; andmining of higher head grades in the earlier years of potential production. The Company is optimistic that the revised mine plan currently being studied as part of the PFS process could deliver similar metal production while mining significantly less material. This could result in potentially significant cost savings. The crushing, processing and waste storage requirements are also expected to be reduced accordingly as would, in this potential scenario, the upfront capex associated with these installations. Anticipated benefits of the revised approach being studied include lower expected execution risks, lower expected pre-production capital and significantly reduced time to first potential production. SolGold is also investigating options that could provide further upside to the value of the Project including: near-surface, open pittable mining options at and near the Alpala deposit; hydroelectric power options to reduce power costs;further metallurgical testing to increase copper, gold and silver recoveries; andelectrification of underground production mobile plant, thereby reducing requirements for fuel, emission control and ventilation with additional likely reductions in capital expenditure and operating costs. A number of proof-of-concept level studies on these options have been initiated beginning with geotechnical and mining options. These are being followed with more detailed studies and are expected to be included in the designs for downstream processes and infrastructure. These studies are on track for the delivery of the PFS in late 2021. The Company is of the view that the Alpala resource is one of the most significant copper-gold porphyry discoveries of the last decade. It has the potential to become a key source of future copper supply amid an expected growing medium-term market deficit, reflecting limited new project development, a declining base production and growing demand supported by the shift towards electrification and decarbonization. SolGold and Cornerstone plan to provide further progress updates as the revised PFS advances during the remainder of the year. Commenting on today’s PFS update, SolGold Interim CEO, Keith Marshall, said: “The revised mine plan being studied underpins the whole of the Alpala Project. The plan being studied is smaller in scale initially, but a much more selective and simpler approach to mining the deposit. In my view, the big advantages of underground mining over open pit mining are sequencing and selectivity. With underground mining you can target which areas of the orebody you want to mine and when. The previously studied plan was the equivalent of an inverted open pit, with limited selectivity, that would likely have resulted in the mining of larger volumes of waste material. We are now studying a plan that would introduce an upper extraction level that may offer earlier access to high grade material. We are also considering dual access, through shafts and a decline which might be developed from both ends concurrently. Through the study of the revised approach, we are hopeful of arriving at a plan that will not sterilize any of the resource, furthering SolGold’s goal of developing the resource with a view to the interests of all stakeholders, particularly Ecuador. I am very encouraged with the progress of the study of this revised approach and I am confident that it should offer a robust but flexible solution to the development of a mine at Alpala.” Qualified Person Yvan Crepeau, MBA, P.Geo., Cornerstone's Vice President, Exploration and a qualified person in accordance with National Instrument 43-101, is responsible for supervising the exploration program at the Cascabel project for Cornerstone and has reviewed and approved the information contained in this news release.

First hole of the Phase 2 program at Brama target (Bramaderos Project, Ecuador) hits mineralized porphyry over shallow 300m intersection
OTTAWA, March 18, 2021 (GLOBE NEWSWIRE) -- Cornerstone Capital Resources Inc. (“Cornerstone” or “the Company”) (TSXV-CGP) (F-GWN) (B-GWN) (OTC-CTNXF) is pleased to provide an update on its Bramaderos gold and copper joint venture in southern Ecuador (see Figure 1) in which it has a 12.5% interest carried by JV partner and project operator Sunstone Metals Inc. (ASX: STM) through to the start of commercial production (see “About Bramaderos”, below). Figures related to this news release can be seen in PDF format by accessing the version of this release on the Company’s website (www.cornerstoneresources.com) or by clicking on the link below: https://cornerstoneresources.com/site/assets/files/5805/nr21-07figures.pdf. HIGHLIGHTS: Visual inspection reveals copper as chalcopyrite1 is present in the first hole (BMDD008) at the Brama porphyry targetThe hole was designed to test the core of the two 3-D magnetic targetsStockwork veining and some copper are visible to the bottom of the first magnetic target at downhole depth of ~450m; Drilling about to hit second target directly below at a downhole depth of ~800mAn historic hole at Brama (BMDD005) intersected 127m at 0.57g/t gold and 0.1% copper, including 39m at 0.72g/t gold and 0.13% copper2; The magnetic model suggests this hole was on the fringe of the target FURTHER INFORMATION: Drilling resumed at the Brama gold-copper porphyry target in February. The hole (BMDD008), which is now at ~735m, is targeting a vertically extensive porphyry system interpreted from 3-D processing of detailed magnetics. The upper part of the targeted porphyry comprises a mineralized intrusive breccia previously drilled in holes BMDD005 and historical hole CURI-13. BMDD005 intersected 127m at 0.57g/t gold and 0.1% copper, including 39m at 0.72g/t gold and 0.13% copper (see Cornerstone news release dated January 21, 2020: https://cornerstoneresources.ca/news-releases/20-02-bramaderos-main-assays-extend-strike-length-of-mineralization-to-650m/), and drilled the margins of the upper magnetic body based on the recent higher resolution 3-D magnetic model. The core of the upper magnetic anomaly is now being targeted in BMDD008. Visual inspection of the BMDD008 drill core is highly encouraging, with the intersection of copper mineralized diorite and a mineralized intrusive breccia in the interval from 150 – 450m. The interpreted 3-D magnetic model shows a sub-vertical elongated magnetic high anomaly below this intrusive breccia which broadens at depth and is also being targeted by this drill hole (Figure 2). Drilling is expected to continue through March and assay results should be available in May. The pipe-like porphyry target being tested at Brama by hole BMDD008 is the first of a significant number of similar vertically extensive pipe-like targets that can be seen in 3-D magnetic data across the Brama, Playas and Melonal porphyry targets on the Bramaderos property. About Bramaderos Measuring 4,948 hectares, the Bramaderos project is located approximately 130km from the Loja provincial capital in southern Ecuador. The project is easily accessible via the Pan American Highway that crosses the property. The Bramaderos concession is owned by La Plata Minerales S.A. (“PLAMIN”), which in turn is owned 87.5% by Sunstone (the project operator) and 12.5% by Cornerstone. Cornerstone’s 12.5% interest is carried by Sunstone through to the start of commercial production and repayable at Libor plus 2% out of 90% of Cornerstone’s share of earnings or dividends from the Bramaderos project (see news release 20-01 dated January 7, 2020). More information about the property can be found at www.cornerstoneresources.com. Qualified Person: Yvan Crepeau, MBA, P.Geo., Cornerstone’s Vice President, Exploration and a qualified person in accordance with National Instrument 43-101, is responsible for supervising the exploration program at the Bramaderos project for Cornerstone and has reviewed and approved the information contained in this news release. Sampling and assaying Surface and drill core samples from Brama were sent to the LAC y Asociados Cia. Ltda. Sample Preparation Facility in Cuenca, Ecuador for sample preparation. The standard sample preparation for drill core samples (Code PRP-910) is: Drying the sample, crushing to size fraction 70% <2mm and splitting the sample to a 250g portion by riffle or Boyd rotary splitter. The 250g sample is then pulverised to >85% passing 75 microns and then split into two 50g pulp samples. Then one of the pulp samples was sent to the MS Analytical Laboratory in Vancouver (Unit 1, 20120 102nd Avenue, Langley, BC V1M 4B4, Canada) for gold and base metal analysis. PLAMIN uses a fire assay gold technique for Au assays (FAS-111) and a four acid multi element technique (IMS-230) for a suite of 48 elements. FAS-111 involves Au by Fire Assay on a 30-gram aliquot, fusion and atomic absorption spectroscopy (AAS) at trace levels. IMS-20 is considered a near total 4 acid technique using a 20g aliquot followed by multi-element analysis by ICP-AES/MS at ultra-trace levels. This analysis technique is considered suitable for this style of mineralization. Standards, blanks and duplicates are inserted ~1/28 samples. The values of the standards range from low to high grade and are considered appropriate to monitor performance of values near cut-off and near the mean grade of the deposit. The check sampling results are monitored and performance issues are communicated to the laboratory if necessary. Sample security was managed through sealed individual samples and sealed bags of multiple samples for secure delivery to the laboratory by permanent staff of the joint venture. MS Analytical is an internationally accredited laboratory that has all its internal procedures heavily scrutinized in order to maintain their accreditation. MS Analytical is accredited to ISO/IEC 17025 2005 Accredited Methods. PLAMIN’s sampling techniques and data have been audited multiple times by independent mining consultants during various project assessments. These audits have concluded that the sampling techniques and data management are to industry standards. All historical data has been validated to the best degree possible and migrated into a database. Rock samples are collected by PLAMIN’s personnel, placed in plastic bags, labeled and sealed, and stored in a secure place until delivery by PLAMIN employees to the LAC y Asociados ISO 9001-2008 certified sample preparation facility in Cuenca, Ecuador. Rock samples are prepared crushing to 70% passing 2 mm (10 mesh), splitting 250 g and pulverizing to 85% passing 75 microns (200 mesh) (MSA code PRP-910). Prepared samples are then shipped to MS Analytical Services (MSA), an ISO 9001-2008 laboratory in Langley, BC, Canada, where samples are assayed for a multi-element suite (MSA code IMS-136, 15.0 g split, Aqua Regia digestion, ICP-AES/MS finish) and gold by Fire Assay (MSA code FAS-111, 30 g fusion, AAS finish). Over limit results for Cu (>1%) are systematically re-assayed (MSA code ICF-6Cu, 0.2 g, 4-acid digestion, ICP-AES finish). Gold is assayed using a 30 g split, Fire Assay (FA) and AAS finish (MSA code FAS 111). Over limit results for Au (>10 g/t) are systematically re-assayed (MSA code FAS-415, FA, 30g., gravimetric finish). Soil samples are dried at low temperature, screened to 80 mesh (MSA code PRP-757); a 15 grams portion is then assayed for a multi-elements suite (MSA code IMS-136, Aqua Regia digestion, ICP-AES/MS finish). Quality assurance / Quality control (QA/QC) The MSA Analytical 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 20-25 samples) as part of PLAMIN’s QA/QC program. Rejects, a 100 g pulp for each rock sample, are stored for future use and controls.

Bramaderos Project Update, Ecuador
Latest assays extend known strike length of Espiritu silver-gold system to 700mOTTAWA, March 17, 2021 (GLOBE NEWSWIRE) -- Cornerstone Capital Resources Inc. (“Cornerstone” or “the Company”) (TSXV-CGP) (F-GWN) (B-GWN) (OTC-CTNXF) is pleased to provide an update on its Bramaderos gold and copper joint venture in southern Ecuador in which it has a 12.5% interest carried by JV partner and project operator Sunstone Metals Inc.

HIGHLIGHTS: Two latest holes (ESDD008 and ESDD009) at Espiritu extend the known strike length of the silver-gold mineralization to 700mDrill hole ESDD009 intersected 2 significant lodes of silver-gold-zinc-lead mineralization including: 2.5m at 65.9g/t silver, 1.63g/t gold from 369.5m0.5m at 141g/t silver, 0.28g/t gold, 0.52% copper, 2.73% lead and 1.15% zinc from 370m0.6m at 154g/t silver, 6.46g/t gold from 371.4m (only 140m below surface) Detailed soil geochemistry has defined several significant anomalous areas to the south-east for drilling Espiritu is one of several similar targets within the Bramaderos project area Cornerstone VP Exploration, Yvan Crepeau, said: “These results provide more evidence that Espiritu is a large silver-gold system. It is still early days in the exploration of this system, and we are still developing models for the style and geometry of mineralization, that will in turn enable us to better target the higher-grade areas. “The early benefits of this approach are seen in drill hole ESDD009, which delivered the highest gold grades we have seen in the system. “We are seeing the suggestion of groupings of discrete surface anomalies – seen clearly in Figure 3 - that we believe probably reflect higher grade shoots, and which will be the focus of ongoing work. We will be exploring individual targets within an area 700m x 1,500m. Locally these areas contain very high grades of silver and we are getting closer to understanding the controls on those higher grades. “Once ESDD011 is completed (Figure 2) we will review all data to plan the next phase of drilling. This will include drilling at Espiritu Southeast (Figure 3) where Espiritu style veining is present at surface and corresponds with a cluster of silver-in-soil anomalies over a strike length of 400m. Espiritu is just one of several similar targets within the Bramaderos Project area, which require further exploration.” FURTHER INFORMATION: Assay results and geological interpretation from holes ESDD008 & 9 show multiple silver-gold bearing structures with various orientations (Figure 1) with local high-grade mineralization (Table 1), including the highest gold grades yet drilled at Espiritu. Drilling of hole ESDD008 was completed at 359.97m. Drill hole ESDD009 was completed at 451.35m and intersected veins a further 250m south of ESDD008 (Figure 1), now taking the strike extent of the Espiritu silver-gold system to 700m. Drill Holes ESDD008 and 009 were drilled at shallow angles to surface, and partly following topography, and have only tested to a maximum vertical depth of 140m below surface. Evidence of multiple lodes continues to be identified in drilling. Narrow high-grade zones appear to narrow and thicken, and better mineralization is interpreted to occur at vein intersections. This is interpreted to generate sub-vertical higher-grade shoots as seen in holes ESDD005 and 006, and to be tested with hole ESDD011 in progress.
