Emgold Provides Exploration Update For its New York Canyon Property, NV

VANCOUVER, BC / ACCESSWIRE / October 4, 2021 / Emgold Mining Corporation (TSXV:EMR)(OTC PINK:EGMCF)(FRA:EMLM)(BSE:EMLM) ("Emgold" or the "Company") is pleased to announce assay results from four exploration diamond core holes and re-assay results from nine historic diamond core holes drilled at its New York Canyon Property, NV (the "Property"). Exploration activities are being carried out by the Company's partner, Kennecott Exploration Company ("KEX"), a subsidiary of Rio Tinto plc (RIO).

The Property is an advanced stage exploration project consisting of three main copper targets which were first explored in the mid-1960's, with the last historic drilling completed in 2006. These historic targets, situated west to east respectively, are called Copper Queen, Champion, and Longshot Ridge.

The Property is subject to an Earn-In with Option to Joint Venture Agreement (the "Agreement") between Emgold and KEX first announced by press release on February 11, 2020. KEX can earn up to a 75% interest in the Property by completing up to US$22.5 million in exploration expenditures. Under the terms of the Agreement, KEX has a First Option to acquire a 55% undivided interest in the Property by incurring US$5.0 million in expenditures over a 5-year period, of which US$1.0 million is a committed expenditure that must be completed prior to the 18-month anniversary of the Agreement. To date, KEX has completed the US$1.0 million committed expenditure and is in the process of completing the First Option.

Significant intercepts from the first four of 10 currently planned drill holes for 2021 on the Property are summarized in Table 1.

Details on the 2021 exploration program, to date, are outlined below. David Watkinson, President and CEO of Emgold, stated, "We are grateful to have KEX as a partner to explore the New York Canyon Property and are excited by the results to date that indicate the potential for a larger copper skarn and porphyry system on the Property. KEX is taking a systematic approach to exploring the Property, including geologic and structural mapping, geophysics, drilling, and other exploration work. KEX has doubled the size of its initial planned drilling program from five hole in 2021 and is now expected to complete at least 10 holes prior to year-end. We look forward to receiving and releasing additional exploration results in the near-future."

About the Property

The Property currently consists of 417 unpatented claims and 21 patented claims totaling approximately 8,700 acres. It is located in the Santa Fe Mining District, Mineral County, west-central Nevada, and about 30 mi. (48 km) east of the town of Hawthorne. KEX is exploring the Property to expand the copper skarn and copper porphyry mineralization. Total historic drilling on the Property, prior to the current drill program, is 234 holes totaling about 43,000 m (139,000 ft).

The Property is an advanced stage exploration project consisting of three main copper targets which were first explored in the mid-1960's, with the last historic drilling done completed in 2006. These historic targets, situated west to east respectively, are called Copper Queen, Champion, and Longshot Ridge. A claim map showing the location of these targets is shown in Figure 1.

Historic Exploration on the Property

From Copper Queen on the west side of the Property to Longshot Ridge on the east side, is a length of 6.4 km (4.0 miles). The average width of the known mineralization is 3.2 km (2.0 miles). Copper mineralization, including skarn and porphyry, has been found in all three deposits.

Copper Queen Target

Historic exploration by Conoco in the 1970's and 1980's defined copper sulfide skarn and porphyry mineralization at the Copper Queen prospect. Drilling reported in a May 10, 1979 internal report included a significant interval of chalcopyrite and molybdenite mineralization in drill-hole MN-42, drilled in 1977. MN-42 intersected 1,020 ft (310.9m) of 0.41% Cu, 0.012% Mo, 4.5 ppm Ag, and 0.1 ppm Au from 560 ft (170.7 m) to 1,580 ft (481.6 m) (true width unknown). Note this hole was drilled prior to the implementation of NI 43-101 Standards of Disclosure for Mineral Projects and QA/QC procedures are unknown. KEX re-assays of MN-42 reported 1,310 ft (399.3 m) of 0.443 CuEq as shown in Table 2, with additional details on individual metal assays shown in Table 9 below.

Champion

The Champion prospect was explored from the late 1960s through the 1970s, although apparently to a lesser extent than Copper Queen and Longshot Ridge. Historic core drilling intersected oxide and sulfide copper skarn mineralization, but historical mineral resources were not delineated.

Longshot Ridge

Oxide skarn mineralization has been drilled at the Longshot Ridge target by various operators since the 1960's. Most recently, Searchlight Resources Inc. (SCLT) (formerly known as Canyon Copper Corporation and Aberdene Mines Limited) drilled the property between 2004 and 2006 and completed a 2010 Technical Report. Searchlight defined an indicated resource of 16.3 million tons (14.8 million tonnes) of 0.43% Cu and an inferred resource of 2.9 million tons (2.6 million tonnes) of 0.31% Cu solely in the Longshot Ridge copper oxide skarn area. A cut-off grade of 0.20% Cu was used. Emgold's Qualified Person has not audited or verified this resource as a current mineral resource and Emgold is therefore treating this resource as a historical estimate according to NI 43-101 Standards of Disclosure. The 2010 Technical Report can be found under Searchlight's corporate filings at www.sedar.com .

Other Targets

The Ideal target is located south of Copper Queen and underlies alluvium. The actual date of its discovery is unknown at this time, although it appears in a 1997 report and map. Ideal appears to be a previously untested geophysical anomaly. Kennecott drilled hole one hole (NYCN0001) into this target and assay samples from this hole did not encounter significant copper values.

2021 Drilling Program to Date by KEX

Kennecott's current plans (as of this press release) are to drill 10 core holes at the Property in 2021 (subject to adjustment). A total of nine holes have been completed to date and drilling of a tenth hole is in progress. Assays have been received for four holes. The status of the current drilling program is shown in Table 3.

Table 3

Drill Program Status

1. Planned depth

Seven holes have targeted the Copper Queen area. Two holes have targeted the Longshot Ridge area. No holes were drilled in the Champion area. A geophysical anomaly, called Ideal, was targeted with one drill hole and is located to the south of the Copper Queen area. The location of the nine drill holes drilled to date and ten drill holes re-assayed by KEX (discussed below in this press release) are shown in Figure 2.

Drill Hole Information

Results from the drilling are shown in Table 5. NYCN0001 drilled into the Ideal geophysical target intersected a magnetic anomaly with no significant copper mineralization. NYCN0002 was a step-out hole from historic hole MN-42 and showed several long-mineralized skarn intercepts including 94.35 m of 0.333% CuEq, 49.34 m of 0.273% CuEq, and 172.28 m of 0.169% CuEq. NYCN0003 and NYCN0004 also showed numerous intercepts greater than or equal to 0.1% CuEq.

2021 Re-Assay Program by KEX

Historic drill core from past drilling programs is stored on the Property. KEX re-assayed selected holes and in some cases selected core intervals of the historic drill core. Table 6 shows details of the original drill holes that were re-assayed by KEX.

Table 6
New York Canyon Property
Re-Assay Drill Hole Information

Table 7 shows the selected intervals that were re-assayed by KEX. Note that MN-202 and MN-221 were selectively sampled with representative 0.2 m long core samples taken at selected intervals which were re-assayed and used for isotope testing.

Table 8 shows the status of the re-assay program. Re-assay information has been received from all holes except MN-27 to date.

Table 9 includes assay results from the re-assay program. Of particular note is the re-assay of MN-42, drilled in 1977, which was reported as intersecting 1,020 ft (310.9 m) of 0.41% Cu, 0.012% Mo, 4.5 ppm Ag, and 0.1 ppm Au from 560 ft (170.7 m) to 1,580 ft (481.6 m) (true width unknown). The re-assay results in Table 9 show 399.29 m of 0.341% Cu, 0.012% Mo, 3.301 ppm Ag, and 0.036 ppm Au. As a direct comparison, for the exact corresponding re-assay interval in MN-42 (from 170.7 m to 481.6 m representing 310.9 m in length), re-assay results of 0.381% Cu, 0.014% Mo, 3.666 ppm Ag, and 0.041 ppm Au were obtained. Note that hole MN-42 was drilled in 1977 and the core has been stored for about 44 years on the Property. The impact of storage on the core over this length of time on assay results is difficult to ascertain. Historic assays were done before the implementation of NI 43-301. Lab detection limits for silver and gold are significantly different than those used in historic lab work. The historic versus re-assay results are relatively comparable.

Note that re-assay intervals tried to copy historic assay intervals from work done in the 1970's. In addition, lab detection limits for gold and silver used today are much lower. However, internal analysis shows that where selective assay intervals could be compared with historic intervals on a footage-to-footage basis, the results were comparable.

QA/QC Methods

Drilling Program

The drill being used is a Boart LF-160. Core is typically PQ in size at the top of the holes, reduced to HQ around 200 to 300 m depth, and further reduced to NQ if needed.

Drill core is initially taken to a field core logging facility on the Property and scanned with an XRF device and quick-logged by the field geologist. Core samples are then shipped to KEX's core logging facility in Salt Lake City, where they are photographed and logged in detail. Detailed logging includes rock types, alteration, and structures. Core is sawn in half, and samples prepared, labeled, and shipped to ALS Laboratories ("ALS") in Elko Nevada. Typically core samples were 1.0 to 3.0 m in length, except for hole NYCN0001 where 10 m composite samples were taken.

ALS is an ISO/IEC 17025:2017 accredited laboratory. ALS prepared the samples and analyzed them using ME-MS61L. If certain elements, including copper, exceeded certain values, additional analyses were done using ME-OG62. Gold, in some cases, was analyzed using method Au-ICP21. The lab inserted standards and duplicates as par of its internal QA/QC program. ALS is independent from both KEX and Emgold.

KEX follows strict QA/QC measures. As part of the KEX QA/QC program, independently certified control samples (standards, blanks, and duplicate samples) were also inserted into the sample stream for each analytical batch. In general, a blank is inserted at the start of each stream and then every 10th sample is a QA/QC sample, alternating between blanks, standards, and duplicates. Standards are inserted with every submitted batch of samples, and to match the level of mineralization as much as possible. Additional blanks are sometimes included before visibly mineralized intervals. Duplicate samples were systematically included. Drill core duplicates are one-quarter core samples. Finally, KEX evaluates the QA/QC results to determine if they meet the company's specifications to ensure proper QA/QC. All holes passed QA/QC in this report.

Re-assaying Program

Historic core samples selected from storage on the Property were shipped to KEX's core logging facility in Salt Lake City, where they are photographed. Of the nine historic holes re-assayed, five holes were relogged. Half core, remaining from historic drilling, was sawed in half (i.e. quartered), and samples were prepared, labeled, and shipped to ALS Laboratories ("ALS") in Elko Nevada. Sample lengths were typically 3.0 m long, except for holes MN-202 and MN-221. In those holes, a 20 cm sample was taken at the beginning at various depths to get representative samples of longer core intervals.

ALS is an ISO/IEC 17025:2017 accredited laboratory. ALS analyzed the samples using the method ME-MS61L. If certain elements, including copper, exceeded certain values, additional analyses were done using ME-OG62. Gold, in some cases, was analyzed using method Au-ICP21. The lab inserted standards and completed duplicates as part of its internal QA/QC program. ALS is independent from both KEX and Emgold.

KEX follows very strict QA/QC measures. As part of the KEX QA/QC program, independently certified control samples (standards, blanks, and duplicate samples) were also inserted into the sample stream for each analytical batch. In general, a blank is inserted at the start of each stream and then every 10th sample is a QA/QC sample, alternating between blanks, standards, and duplicates. Standards are inserted to match the level of mineralization ad much as possible. Duplicate samples were systematically included. As previously noted, KEX evaluates the QA/QC results to determine if they meet the company's specifications

and to ensure proper QA/QC. All historical holes passed QA/QC in this report.
