Doré Copper intersects 6.92% Copper, 3.1 g/t Gold and 24.2 g/t Silver over 3.4 meters at Cedar Bay Central Vein

Toronto, Ontario – September 15, 2020 – Doré Copper Mining Corp. (the “Company” or “Doré Copper“) (TSXV: DCMC) is pleased to announce results from its ongoing 2020 drill program at the Cedar Bay deposit, located in the Lac Doré mining camp near Chibougamau, Québec. Today’s results demonstrate the extensions of the Cedar Bay Central, 10-20 A and B veins.

Drilling Highlights

CDR-20-08AW1 – Central vein: 3.4 meters of 6.92% copper (Cu), 3.1 g/t gold (Au), and 24.2 g/t silver (Ag) approximately 75 meters down dip and along strike from hole CB-27-9 that intercepted 2.0 meters (TW) of 15.2 g/t Au and 4.8% Cu and 100 meters up dip and along strike from hole CDR-20-04C that intercepted 1.2 meters (TW) of 14.2% Cu and 1.16 g/t Au.
CDR-20-08A – 10-20A vein: 1.7 meters of 7.57 g/t Au, 1.65% Cu and 15.8 g/t Ag. This is located approximately 250 m down plunge of CDR-18-02W2 that intercepted 2.9 meters (TW) of 12.25 g/t Au and 1.2% Cu.

Ernest Mast, President and CEO of Doré Copper stated, “These latest intercepts at Cedar Bay potentially extend the mineralization of the Central, 10-20 A and 10-20 B veins. The higher-grade gold nature of the intercepts supports the thesis of orogenic gold enrichment of the Cedar Bay veins. The intercept on the Central vein follows up on the high-grade intercept CDR-20-04C of 14.2% Cu over 1.5 meters from earlier this year. The large potential downdip extension of the 10-20 A and B veins is extremely promising. Following the completion of the drilling campaign, the Company is expected to have an updated mineral resource estimate by H1/21 to support an eventual hub-and-spoke restart of the camp along with the Corner Bay and Joe Mann deposits using our existing 2,700 tpd mill as a central processing facility.”

Cedar Bay Drill Program

The two holes crossed the Main, Central and 10-20A and 10-20B veins. Mineralized intercepts are highlighted in Table 1 with hole locations on Figure 1.

Hole CDR 20-08A was drilled from the west close to the collar location used in the 2018 drill program when the Company was private. The hole was initiated with an azimuth of 66 degrees and a dip of -63.5 degrees. Hole CDR-20-08AW1 was then wedged at a depth of 700 meters. The Central vein and 10-20 veins that are adjacent to the existing shaft were targeted (Figure 2).

Prior drill results from Cedar Bay were announced on August 4, 2020 for the Central vein, Main Vein, Zone 21 and the Copper Cliff Crown Pillar. Of note, in the August 4, 2020 news release, hole CDR-20-04C intersected 1.2 meters (TW) of 14.2% Cu and 1.16 g/t Au. Hole CDR-20-08AW1 intercepted mineralization between that intercept and a high-grade historic intercept of 2.0 meters (TW) of 15.2 g/t Au and 4.8% Cu from hole CB-27-9.

The vertical extension of the 10-20 A and 10-20 B structures was extended by approximately 250 meters downdip as demonstrated by Hole CDR-20-08AW1. The structure between the CDR-20-08AW1 intercepts and the historical holes on the 10-20 A and B structures will be tested by CDR-20-08AW2.

Table 1. Cedar Bay Property Drill Assay Highlights

Hole	Structure	From(m)	To(m)	Length¹ (m)	Cu(%)	Au(g/t)	Ag(g/t)
CDR-20-08A	10-20A	1,454.5	1,456.2	1.7	1.65	7.57	17.4
CDR 20- 08A-	10-20B	1,440.2	1,442.4	2.2	1.67	1.67	20.7
CDR-20-08AW1	Main	1,090.4	1,093.0	2.6	0.96	1.88	8.7
CDR-20-08AW1	Central	1,315.5	1,318.9	3.4	6.92	3.10	24.2

The true width of the structures intersected is estimated at approximately 50% of the downhole width.

Cedar Bay Property

The Cedar Bay property is located five kilometers by road from the Company’s Copper Rand Mill that operated from 1959 to 1990 producing 3.9 million tonnes grading 1.63% Cu and 3.21 g/t Au. The deposit is comprised of multiple parallel to sub-parallel, NW-SE striking, steeply dipping extensional shears which are mineralized with semi-massive to massive sulfides (Cpy +/- Py +/- Po). All deposits along the Lac Doré complex share the same general attributes. At Cedar Bay, there are currently five identified parallel zones – Main 1 and 2, Central, 10-20 A and B (from SW to NE), as well as several other smaller lenses in between.

Cedar Bay’s mineral resources consist of an indicated resource of 130,000 tonnes grading 9.44 g/t Au and 1.55% Cu and an inferred resource of 230,000 tonnes grading 8.32 g/t Au and 2.13% Cu, all located in the 10-20A, 10-20B and Central structures (2019 NI 43-101 Technical Report – all resources are reported on a minimum 2 meter vein width).

Drilling and Quality Control

The Company is using Miiken Drilling as the drilling contractor. Miiken is a joint venture between Chibougamau Diamond Drilling Ltd., the First Nations community of Ouje-Bougoumou and the First Nations community of Mistissini both located in the Eeyou Istchee territory.

Sample preparation and assays were done at SGS lab in Val-d’Or, Québec. Samples were weighed, dried, crushed to 75% passing 2 mm, split 250 g, pulverized to 85% passing 75 microns. Samples were then fire assayed for Au (30 g) and sodium peroxide fusion ICP-MS finish for 34 elements.

QA/QC is done in house by Doré Copper Geologists with oversight from the Exploration Manager, The check samples (blanks and standards – 4% of total samples with another 2% of core duplicates) that were inserted into the sample batches are verified against their certified values and are deemed a pass if they are within 3 standard deviations of the certified value. The duplicates are evaluated against each other to determine mineralization distribution (nugget). If there are large discrepancies in the check samples, then the entire batch is requested to be re-assayed.

Historical drilling results disclosed in this news release about Corner Bay and Cedar Bay are taken from the technical report entitled “Technical Report on the Corner Bay and Cedar Bay Projects, Northwest Québec, Canada” dated June 15, 2019, prepared by Luke Evans, M.Sc., P.Eng., which is available under Doré Copper’s profile on SEDAR at www.sedar.com.

Andrey Rinta, P.Geo., the Exploration Manager of the Corporation and a “Qualified Person” within the meaning of National Instrument 43-101, has reviewed and approved the technical information contained in this news release.

Doré Copper intersects 14.2% Copper, 1.16 g/t Gold and 28.0 g/t Silver over 1.5 meters at Cedar Bay and intersects High-grade vein in crown pillar at Copper Cliff

Download PDF English | French

Toronto, Ontario – August 5, 2020 – Doré Copper Mining Corp. (the “Company” or “Doré Copper“) (TSXV: DCMC) is pleased to announce results from its ongoing 2020 drill program at the Cedar Bay deposit. These results show the extension of the Cedar Bay Central Vein and has identified new targets in Zone 21 and the Crown Pillar of the adjacent Copper Cliff mine. The Cedar Bay program is focused on testing the lateral extension of the 10-20 and Central veins and the vertical extension of the Main vein. Ongoing drilling is testing the down-dip extension of historical intercepts on the 10-20A and 10-20B veins and the Main vein below the lowest historic mine workings.

Drilling Highlights (refer to Table 1):

CDR-20-04CB – Central Vein: 1.5 meters of 14.2% copper (Cu), 1.16 g/t gold (Au) and 28.0 g/t silver (Ag) (TW approx. 1.2 meters) approximately 160 meters down dip and along strike from hole CB-27-9 that intercepted 2.0 meters (TW) of 15. g/t Au and 4.8% Cu.
CDR-20-07 – Zone 21_1: 2.25 meters of 4.9% Cu, 0.46 g/t Au and 8.6 g/t Ag (TW of approx. 1.3 meters).
Four intercepts in the crown pillar of the adjacent Copper Cliff Mine, including CDR-20-04B intersecting 2.3 meters (TW) of 7.3% Cu, 13.6 g/t Au and 38.4 g/t Ag, with the four intercepts averaging 5.0 meters of 3.65% Cu, 5.31 g/t Au and 20.5 g/t Ag (TW of approx. 2.2 meters) between two intercept areas.

Ernest Mast, President and CEO of Doré Copper Mining Corp. stated, “The latest intercepts at Cedar Bay support the expansion of mineralization in the Central zone with the highest-grade copper intercept received to date. The identification of a potential expansion of Zone 21 and the presence of high-grade veins in the Crown Pillar of the Copper Cliff mine further highlight the upside of this deposit. The results continue to support the eventual hub-and-spoke restart of the camp along with the Corner Bay and Joe Mann deposits using our existing 2,700 tpd mill as a central processing facility.”

Cedar Bay Drill Program

Cedar Bay Property

The Cedar Bay property is located five kilometers by road from the Company’s Copper Rand Mill that operated from 1959 to 1990 producing 3,900,000 tonnes grading 1.63% Cu and 3.21 g/t Au. The deposit comprises multiple parallel to sub-parallel, NW-SE striking, steeply dipping extensional shears which are mineralized with semi-massive to massive sulfides (Cpy +/- Py +/- Po). All deposits along the Lac Doré complex share the same general attributes. At Cedar Bay there are currently 5 identified parallel zones – Main 1&2, Central, 10_20 A&B (from SW to NE) as well as several other smaller lenses in between.

A plan view is shown in Figure 1 below.

Figure 1. 2018 drilling as well as hole CDR-20-08A was done from the west and the 2020 directional program as well as the follow up hole beneath Zone 21 was done from the East/North side of the deposit.

Cedar Bay has 130,000 tonnes of estimated indicated resources grading 9.44 g/t Au and 1.55% Cu and 230,000 tonnes of inferred resources grading 8.32 g/t Au and 2.13% Cu, all located in the 10-20A, 10-20B and Central structures (In the 2019 43-101 technical report all resources are reported on a minimum 2 m vein width). In addition, at the time of mine closure there are historical resources of 250,000 tonnes grading 5.5 g/t Au and 0.97% Cu in the main vein and 10-20 structures immediately below the deepest mining level of 670 meters (the mine shaft extends to 1036 meters).

Central, Main and 10-20A and 10-20B veins

Holes CDR 20-04 and 20-05 were drilled from the Copper Cliff property to intersect the parallel mineralized structures at Cedar Bay employing directional drilling technology. The holes were drilled to test the strike extensions of the resources defined in 2019. Both holes were initiated with a dip of -60 degrees and then were corrected using Aziwell directional drilling to -19 degrees, -35 degrees (for the two cut-offs on hole 4C) and -38 degrees on hole 5. A third cut was prepared on hole CDR-20-04C and will be drilled once contractor travel can be arranged in the very near future. The holes are targeting mineralization in the Main veins, Central vein and 10-20 veins that are adjacent to the existing shaft (see figure 2 below).

Figure 2. Section view showing the drill traces of the directional holes drilled from Copper Cliff (NE). Yellow trace depicts the pilot hole and cut-offs for hole 4C, blue depicts the trace for hole 5. In bright red are the 10_20A&B veins and the Central vein within which the 2018 resources are contained. The pale red consists of the projected Main zone veins.

The program initiated in early March and was stopped on March 24^th due to the COVID-19 measures announced by the Québec government. The program was reinitiated on May 14^th and the Company and its contractors implemented protocols to ensure best health practices and communicating these to local stakeholders. After completing the preparation of the third cut on hole CDR-20-04C, the directional drilling crew finished their shift and a replacement group of technicians was not available therefore the down-dip follow-up of hole CDR-20-04CB will be tested at a later date. Drilling is currently testing the down dip from holes CDR-18-02W2 that intercepted 2.4 meters grading 4.54% Cu and 15.4 g/t Au and CDR-18-03 that intercepted 2.4 meters of 1.67% Cu and 19.5 g/t Au on 10-20 A and 3.3 meters grading 5.1 g/t Au and 1.4% Cu on the Central vein.

Each hole crossed the host structure of the mineralized veins, however, only two of the intercepts on the Central vein, Main vein and 10-20A and 10-20B hit economic-grade mineralization and are highlighted in Table 1. The high-grade copper intercept on hole CDR-20-04CB, 14.2% Cu and 1.16 g/t Au over 1.5 meters is located approximately 160 meters down dip and along strike from hole CB-27-9 that intercepted over a two meter true width, 4.8% Cu and 15.2 g/t Au. The high-grade Central vein remains open down dip and along strike to the north-west. Hole CDR-18-08A and a wedge currently underway will test the area between the two intercepts on the central vein as well as the down-dip extensions of the 10-20 A and B veins. Typically, ore within the Lac Doré complex exhibits a steep plunge. The current drilling will help better characterize the behaviour and plunge of the ore shoots of the Central, 10-20 A and 10-B structures. The intercept on the Main vein, CDR-20-04CB of 2.0 meters grading 2.87 g/t Au and 0.3% Cu is located 160 meters down dip of historic intercept CB-27-3 that intersected 5.8 meters of 2.0 g/t Au and 0.4% Cu. CDR-20-05 was testing the 10-20, Central and Main veins 100 m along strike towards a fault which terminates the mineralization to the SE.

Zone 21

Zone 21 occurs as the north-easternmost vein at Cedar Bay or south-westernmost at Copper Cliff and was mined over the historic Copper Cliff and Cedar Bay claims. The zone mined had a strike of 150-200 meters and a vertical extent of 400 m (490 m from surface). The western half of the mineralized zone is on Doré Copper land. Hole CDR-20-07 targeted the down-dip extension of the ore body on its west side approximately 40 meters beneath the lowest mining level and intersected 2.25 meters grading 4.9% Cu, 0.46 g/t Au and 8.6 g/t Ag.Twenty-two meters downhole was the intercept of a secondary parallel vein of 2.1 meters grading 2.4% Cu, 0.34 g/t Au, and 8.4 g/t Ag. The deposit remains open down dip and along strike at this level. Hole CDR-20-06 tested Zone 21 approximately 100 meters along strike to the NW of previous mining areas at a depth of 300 meters and did not intersect mineralization.

Copper Cliff Crown Pillar

The Copper Cliff crown pillar is 85 m in height down dip according to historic sections and plans with the first development level being that depth below the surface. In the course of our 2020 program at Cedar Bay, the drill holes were collared at Copper Cliff and drilled SW. Near surface the crown pillar was intersected by 3 of the holes with high-grade Cu and Au mineralization in hole CDR-20-04 (C & CB) and a lower-grade intercept in hole CDR-20-05. Historic drilling crossed more than 4 zones near surface. Further drill testing needs to be completed along strike and from the surface to 85 m as they may provide near-surface potential resources.

Drilling and Quality Control

QA/QC is done in house by Dore Copper Geologists with oversight from the Exploration Manager, The check samples (blanks and standards – 4% of total samples with another 2% of core duplicates) that were inserted into the sample batches are verified against their certified values and are deemed a pass if they are within 3sd of the certified value. The duplicates are evaluated against each other to determine mineralization distribution (nugget). If there are large discrepancies in the check samples, then the entire batch is requested to be re-assayed.

The historical drilling results disclosed in this news release about Corner Bay and Cedar Bay was taken from the technical report entitled “Technical Report on the Corner Bay and Cedar Bay Projects, Northwest Québec, Canada” dated June 15, 2019, prepared by Luke Evans, M.Sc., P.Eng., which is available under Doré Copper’s profile on SEDAR at www.sedar.com.

Doré Copper to commence drilling on High-grade Gold Joe Mann property in Québec

Download PDF English | French

First drilling program to target high-grade extensions

Toronto, Ontario – July 30, 2020 – Doré Copper Mining Corp. (the “Company” or “Doré Copper“) (TSXV: DCMC) is pleased to announce that it has received the permit associated with the drilling of the Joe Mann property in Québec, Canada. The Joe Mann property is part of the option agreement announced by the Company on January 2, 2020. The Company has also advised local stakeholders of its drilling plans at Joe Mann. Drilling will commence in approximately two weeks once the current drilling program at Doré Copper’s Cedar Bay property is completed.

“We are excited to focus on our high priority exploration targets at this high-grade gold underground asset that remains open at depth and along strike, given market fundamentals that have strengthened gold prices to record-setting highs,” commented Ernest Mast, President and CEO of Doré Copper.

The two drill rigs will follow up on holes EE-188 and EE-189B that were drilled in 2008 after the mine had ceased operations. Hole EE-188 intersected 3.02 meters grading 30.3 grams per tonne (g/t) gold (Au) and 1.30% copper (Cu). Hole EE-189B intersected 1.88 meters grading 26.66 g/t Au and 0.40% Cu. The intersections are 150 meters apart and approximately 170 meters beneath the lowest mining level in the mine. No prior drilling has occurred to follow up on the high-grade extensions. A long section view of the area that will be drilled is shown below.

The Joe Mann Gold Mine was one of the highest-grade gold mines in Canada and produced 1.17 million ounces of gold grading 8.26 g/t between 1956 and 2007. The mine is located approximately 60 kilometers from the Company’s Copper Rand mill, where ore from Joe Mann was processed from 2004 until its closure in 2007, and is accessible by all season roads.

Highlights of the Joe Mann Gold Mine:

Production of 1.173 million ounces of gold at a grade of 8.26 g/t Au, 607,000 ounces of silver at 5 g/t Ag and 28.7 million pounds of copper at 0.25% Cu (Source: Technical Report on the Joe Mann Mining Property dated January 11, 2016, prepared by Geologica Inc.).
Mineralization remains strong and persistent at depth with hole EE-189B intersecting 26.66 g/t Au over 1.8 meters and hole EE-188 intersecting 30.3 g/t Au and 1.3% Cu over 3.02 meters, extending the Main Zone 170 meters down dip.
The more recently discovered West Zone, a potential structural off-set remains open and is a high priority future exploration target with historical intercepts including 2.44 meters at 24.62 g/t Au, 3.93 meters at 31.54 g/t Au, 2.62 meters at 24.28 g/t Au and 3.2 meters at 16.1 g/t Au.
Exploration potential remains excellent including new parallel zones identified by recent surface prospecting work that lie just several hundred meters to the south of the main mine.
Well-developed infrastructure in place including year-round road access, administration office, power and a shaft down to the 1,145-meter level.

The Company plans to drill two holes in close proximity to the historical holes, with a minimum of one wedge per hole. The drill collars will be located on the adjacent property, also named Joe Mann, a joint venture between Jessie Resources (65%) (optioned by Doré Copper) and SOQUEM (35%). The holes will cross an untested area of the Rohault Zone which is part of the 65/35 joint venture. The closest intersection to those planned on Rohault comes from hole H-156 which intersected 0.67 meters at 11.0 g/t Au. SOQUEM will contribute 35% of the field costs of the joint venture. A plan view of Joe Mann’s planned drill holes and infrastructure is presented below.

Andrey Rinta, P.Geo., the Exploration Manager of the Company and a “Qualified Person” within the meaning of National Instrument 43-101, has reviewed and approved the technical information contained in this news release.

Doré Copper Stepout Drilling Extends Corner Bay Mineralization by 200 meters Intersecting 7.25 meters at 2.46% copper, 0.59 g/t gold and 5.0 g/t silver (tw approx. 4.26 meters)

Download PDF English | French

Toronto, Ontario – April 22, 2020 – Doré Copper Mining Corp. (the “Company” or “Doré Copper“) (TSXV: DCMC) is pleased to announce two additional intercepts from its 2020 drill program at the Corner Bay deposit. These results complete the assays for drill holes announced on March 3^rd, 2020. The two holes extend the deposit approximately 200 meters downdip with the deposit remaining open along strike and down plunge.

Highlights:

CB-20-16: 7.25 meters of 2.46% Cu, 0.59 g/t Au and 5.0 g/t Ag (TW approx. 4.26 meters).
CB-20-16W1: 2.3 meters of 2.67% Cu, 0.17 g/t Au and 6.2 g/t Ag (TW approx. 1.5 meters). This was part of a large mineralized shear zone of 33.1 m (TW 21.85 m) assaying 0.56% Cu.

The Company’s drilling program was stopped on March 24^th when the Québec government announced the stoppage of all non-essential businesses due to the COVID-19 pandemic. Once the government declares mineral exploration an essential business, drilling is expected to resume shortly thereafter at the Cedar Bay deposit where previous drilling returned numerous high-grade intercepts including 2.4 m grading 19.5 g/t Au and 1.67% Cu in hole CDR-18-02, and 2.4 m grading 15.4 g/t Au and 4.54% Cu in hole CDR-18-03.

Ernest Mast, President and CEO of Doré Copper Mining Corp. stated, “The latest two intercepts at Corner Bay support the continuity of mineralization and demonstrate the potential to continue to grow the deposit towards the south along strike and down plunge. This supports the eventual hub-and-spoke restart of the camp using our existing 2,700 tpd mill. CB-20-16W1 is particularly interesting as the intercept was part of a 33.1 m shear zone that assayed 0.56% Cu. This is one of the thickest mineralized shear zones drilled at Corner Bay indicating potential for higher grade very thick mineralized zones.”

Corner Bay Drill Program

The CB-20-16 and CB-20-16W1 intercepts extend the main deposit beneath the diorite dyke downdip by approximately 200 meters. These holes follow up the 2020 results announced on March 3^rd that include CB-20-17 that intersected 7.0 meters of 9.08% Cu and 0.41 g/t Au.

Table 1 – Drill intercepts from drilling at Corner Bay completing initial 2020 drill program

Hole	From (m)	To (m)	Width* (m)	Cu (%)	Au (g/t)	Ag (g/t)
CB-20-16	1187.95	1195.2	7.25	2.46	0.59	5.0
CB-20-16W1	1156.0	1158.3	2.3	2.67	0.17	6.2

*True widths are estimated to be 60% for CB-20-16 and 65% for CB-20-16W1.

Hole CB-20-16 was drilled with an azimuth of 89 degrees and dip of 69.5 degrees. Hole CB-20-16W1 was drilled with an azimuth of 89 degrees and dip after wedge of 66 degrees.

An isometric view of the intercepts is shown below in a long section of the southern area of the deposit below the dyke.

Figure 1 – Long section view of the southern area of the Corner Bay Main Zone below the dyke including the two most recent intercepts. See Figure 2 for the view of the entire deposit.

Figure 2 – Long section of the main vein of the Corner Bay deposit indicating areas where the deposit is open. The diorite dyke is vertical and the main vein dips approximately 75 degrees to the west (out of the page). Therefore, the dyke splits the mineralized body with the upper portion to the east of the dyke and the deeper portion to the west. There is mineralization on each side of the dyke at respective levels.

The Corner Bay project has an indicated resource of 1.35 Mt at average grades of 3.01% Cu and 0.29 g/t Au, containing 89.8 Mlb of copper and 13,000 ounces of gold, and an inferred resource of 1.66 Mt at average grades of 3.84% Cu and 0.27 g/t Au, containing 140.3 Mlb of copper and 15,000 ounces of gold, assuming a cut-off grade of 1.5% Cu and a copper price of US$3.25 per pound (Source: Technical Report on the Corner Bay and Cedar Bay Projects, Northwest Québec, Canada, dated June 15, 2019, prepared by Luke Evans, M.Sc., P.Eng.).

Cedar Bay Property

The Company currently has two drill rigs at Cedar Bay. The drills stopped on March 24^th, due to the stoppage of non-essential businesses declared by the Québec government as a response to the COVID-19 pandemic. Once exploration activities will be classified as essential, the Company expects to resume its drilling operations while implementing hygiene and personal distancing measures to stop the spread of the virus.

The ongoing drill program at Cedar Bay will test the 10-20 zone that consists of three (currently defined) parallel veins where previous drilling returned numerous high-grade copper and gold intercepts including 2.4 m grading 19.5 g/t Au and 1.67% Cu in hole CDR-18-02, and 2.4 m grading 15.4 g/t Au and 4.54% Cu in hole CDR-18-03. The drill program will also test the main Cedar Bay vein at depth.

QA/QC is done in-house by Doré Copper geologists with oversight from the Exploration Manager, The check samples (blanks and standards – 4% of total samples with another 2% of core duplicates) that were inserted into the sample batches are verified against their certified values and are deemed a pass if they are within 3sd of the certified value. The duplicates are evaluated against each other to determine mineralization distribution (nugget). If there are large discrepancies in the check samples, then the entire batch is requested to be re-assayed.

Toronto, Ontario – March 24, 2020 – Doré Copper Mining Corp. (the “Corporation” or “Doré Copper“) (TSXV: DCMC) announces that it has suspended its current drilling program. The Quebec Government announced the stoppage of all non-essential businesses effective March 24th at midnight until at least April 13th. At the time of the suspension two drills were operating at the Cedar Bay property near Chibougamau, Québec. The Corporation anticipates that when non-essential businesses can resume operations, the two drill holes currently underway will be able to resume promptly.

The Corporation will maintain security personnel at the Copper Rand site. Company personnel will follow protocols consistent with minimizing the spread of the Covid-19 virus.

The drilling at Cedar Bay was part of the drill program announced on January 6th, 2020 (see press release) and will test the 10-20 zone at the shaft level. The 10-20 zone consists of three parallel veins where previous drilling returned numerous high-grade gold and copper intercepts including 2.4 m grading 19.5 g/t Au and 1.67% Cu in hole CDR-18-02, and 2.4 grading 15.4 g/t Au and 4.54% Cu in hole CDR-18-03. The drill program will also test the main Cedar Bay vein at depth.

The Corporation is using Miiken Drilling as the drilling contractor. Miiken is a joint venture between Chibougamau Diamond Drilling Ltd., the First Nations community of Ouje-Bougoumou and the First Nations community of Mistissini both located in the Eeyou Istchee territory.
