TORONTO, ON / ACCESSWIRE / October 19, 2021 / Anaconda Mining Inc. ("Anaconda" or the "Company") (TSX:ANX)(OTCQX:ANXGF) is pleased to announce an updated Mineral Resource Estimate ("Mineral Resource") for the Stog'er Tight Deposit, part of the Point Rousse Project ("Point Rousse"), prepared in accordance with National Instrument 43-101 ("NI 43-101") and 2019 CIM MRMR Best Practice Guidelines. The Mineral Resource was prepared by Independent Qualified Person Glen Kuntz, P.Geo., of Nordmin Engineering Ltd. ("Nordmin"). All dollar amounts are in Canadian dollars.
The Stog'er Tight Mineral Resource includes an Indicated Mineral Resource of 642,000 tonnes at a grade of 3.02 grams per tonne ("g/t") gold for 62,300 ounces and an Inferred Mineral Resource of 53,000 tonnes at a grade of 5.63 g/t gold for 9,600 ounces. These Mineral Resources are constrained within three open pits as well as adjacent to the past producing Stog'er Tight Mine. The Stog'er Tight deposit is located three kilometres from the Pine Cove mill along existing roads and was previously processed at the Pine Cove mill from June 2018 to January 2020, achieving an average recovery rate of
"The growth of the Stog'er Tight Deposit, now including 62,300 ounces of Indicated Mineral Resource and 9,600 ounces of Inferred Mineral Resource within constrained open pit shells, is a significant milestone in our strategy to expand the life of mine at our Point Rousse operations. Given the relative high grade nature of the Mineral Resource and its proximity to the Pine Cove mill and existing road networks, we have initiated development work required to enable us to convert these resources to reserves. We anticipate results from this work in the fourth quarter of 2021. Consequently, environmental baseline studies have been in progress throughout the 2021 field season and we anticipate the submission of an environmental registration document in the fourth quarter of 2021. We believe the Stog'er Tight resource combined with the recently announced Argyle Mineral Reserve demonstrate potential for an expanded mine life at the Point Rousse operation for several years. Given our history of discovery at Point Rousse and ongoing drill testing of additional targets at both the Point Rousse and Tilt Cove projects, we believe the Point Rousse Project has the potential for continued cash generation for several years and beyond."

Stog'er Tight Development and Permitting
The Stog'er Tight Deposit is located three (3) kilometres east of the Pine Cove Mill and has been defined over a strike length of 1,250 metres to date. Anaconda produced a total of 17,102 ounces of gold from 349,942 tonnes of ore from the Stog'er Tight Mine between June 2018 and January 2020. Gold from Stog'er Tight was recovered through the Pine Cove Mill with an average head grade of 1.75 g/t gold at an overall recovery of approximately
Baseline studies to support an enhanced registration document were initiated in Spring 2021. These studies have included avifauna, bat, and rare plant surveys, as well as fish and fish habitat assessments and surface and groundwater monitoring Fish and fish habitat data will be used to support the development of a Fisheries Act Authorization application and a fish habitat offsetting plan, which are also expected to be submitted in Q1 of 2022.
Stog'er Tight Mineral Resource
The Mineral Resource was prepared by Independent Qualified Person, Glen Kuntz, P. Geo. of Nordmin. The Stog'er Tight Mineral Resource is based on validated results of 690 surface drill holes (506 diamond drill holes and 184 percussive drill holes), for a total of 37,584 metres of diamond drilling that was completed between 1988 and 2021 and the effective date of September 1, 2021. From these drill holes a total of 16,319 samples were analyzed for gold content. The Mineral Resource is defined at a 0.59 g/t gold cut-off and is based upon 1 metre assay composites using a variable gold grade cap. The Open pit constrained Mineral Resource (Table 1) uses the unit cost assumptions outlined in Table 2.

Geological Domaining Stog'er Tight Deposit
Nordmin undertook a full re-examination of the mineralogical, lithological, and structural correlations influencing the gold bearing structures present at the Stog'er Tight deposit. Detailed wireframing was carried out based on vertical 15 m spaced cross-sections and subsequently joined section to section. Each wireframe was given an individual numeric identifier, from there a domain type was assigned within based on the location and nature of the intercept (1=Flat, 2=Steep) Figure 1. A cut-off grade of 0.50 g/t Au was utilized in the creation of the wireframes at the Stog'er Tight deposit.
Explicit modelling was used to create the Mineral Resource, which allows for mineralization to better reflect the Deposit geology and associated geochemistry. Nordmin's opinion is that the explicit modelling approach minimizes risks compared to using implicit modelling for the Project.
Figure 1: Geological domains (Flat and Steep structures).
Exploratory Data Analysis
The exploratory data analysis was conducted on raw drill hole data to determine the nature of the gold distribution within the flat-steep mineralized trends, correlation of grades within individual domains, and the identification of high-grade outlier samples. Nordmin used a geostatistical package (X10 Geo) to complete various descriptive statistics, histograms, probability plots, and XY scatter plots to analyze the grade population data. The findings of the exploratory data analysis were used to help define modelling procedures and parameters used in the Mineral Resource Estimate.
Data received from the Company had been cleaned and edited prior to use in the resource estimate. No significant issues were noted in drill hole collar locations, survey, assay, and lithology data supplied to Nordmin.
Individual drill hole tables (collar, survey, assay, etc.) were merged to create one single master drill hole file. The process splits assay intervals to allow for all records in all tables to be included.
Stog'er Tight Compositing
The raw sample data was found to have a very consistent range of sample lengths. Samples captured within all wireframes were composited to 1.0 m regular intervals based on the observed modal distribution of sample lengths, which supports a 3.0 m x 3.0 m x 3.0 m block model (Northing x Easting x Elevation) with three sub-blocking levels (a minimum size of Northing = 0.375 m x Easting = 0.375 m x Variable Elevation). An option to use a slightly variable composite length was chosen to allow for backstitching shorter composites located along the edges of the composited interval. All composite samples were generated within each background low-grade, northwest-southeast, and east-west wireframe. There are no overlaps along boundaries. The composite samples were statistically validated to ensure no material loss of data or change to each sample population's mean grade.
Nordmin reviewed the previous historical estimate capping method and determined that a more appropriate method would be to assign capping values based on the geological and structural features present on site. Therefore, the assays were variably capped by domain type (flat, steep and background) Table 3.

Stog'er Tight Assessment of Spatial Grade Continuity
Datamine and Sage 2001 was used to determine the geostatistical relationships for each deposit. Independent variography was performed on composite data for each domain. Experimental grade variograms were calculated from the capped/composited sample gold data to determine the approximate search ellipse dimensions and orientations.
The analyses considered the following:
- Downhole variograms were created and modelled to define the nugget effect;
- Experimental pairwise-relative correlogram variograms were calculated to determine directional variograms for the strike and down dip orientations;
- Variograms were modelled using an exponential with practical range;
- Directional variograms were modelled using the nugget defined in the downhole variography and the ranges for the along strike, perpendicular to strike, and down dip directions;
- Variograms outputs were re-oriented to reflect the orientation of the mineralization; and
- The analysis demonstrated that gold continuity could be appropriately defined by one main variogram across all domains.
