TORONTO, Jan. 16, 2020 /CNW/ - Anaconda Mining Inc.
("Anaconda" or the "Company") (ANX: TSX) (OTCQX: ANXGF) is pleased
to announce the results of an underground bulk sample program (the
"Bulk Sample") undertaken at its 100%-owned Goldboro Gold Project
("Goldboro" or the "Project") located in Nova Scotia, Canada. The objectives of the
Bulk Sample were to confirm the geological interpretation of the
deposit, test for spatial and grade continuity of the mineralized
structures, validate key assumptions of the updated Mineral
Resource model, and test certain types of mining methods.
Key Takeaways of the Bulk Sample
- Successfully tested a large area within the 2019 Mineral
Resource Estimate1 with respect to continuity of gold
grade and geological interpretation, confirming the position and
continuity of mineralized zones;
- The average diluted mine grade based on grade
control samples2 of 3.51 g/t gold reconciles well with
the average undiluted grade of the Mineral Resource
block model of 3.81 g/t gold in the area of the Bulk Sample (both
capped at 80 g/t);
- The average head grade of 3.81 g/t gold from the Pine Cove Mill
shows a positive reconciliation of 8.5% to the mine grade of 3.51
g/t gold, demonstrating an upside bias within an acceptable
range;
- High gravity recovery of 51%, confirming metallurgical test
work; and
- Demonstration of excellent ground conditions through test
mining and successful testing of certain underground mining methods
to optimally extract the Mineral Resource.

The delays in processing and completing the Bulk Sample were the
result of shipping challenges experienced in the summer of 2019
(see Update on Statement of Claim section below) and the timing in
receiving refining results on certain portions of the processed
material.
"Anaconda is pleased to announce the results of the Goldboro
Bulk Sample, a key milestone in the advancement towards a
construction decision. We are very encouraged with the excellent
results of test mining where the average diluted mine grades
reconciled well with the estimated undiluted block model grades,
providing further confidence in the updated Mineral Resource. The
underground component portion of the Measured and Indicated Mineral
Resource grade for the entire Goldboro Deposit is 6.18 g/t gold at
a 2.0 g/t gold cut-off grade. The positive Bulk Sample results
demonstrate a slightly positive reconciliation to the mined grade,
within acceptable limits, thereby giving further confidence in the
Mineral Resource being used as the basis for the Feasibility Study,
which is expected to be announced in Q1 2020. Furthermore, the
processing of the bulk sample material demonstrated excellent
gravity recovery of 51%, which confirms the gravity test work
undertaken as part of the overall metallurgical test
program."

CEO, Anaconda Mining Inc.
Geology and Test Mining
The Bulk Sample was extracted from the Boston-Richardson Gold
System within the Goldboro Deposit, leveraging existing decline and
cross cuts developed in the late 1980's to minimize the development
needed to access mineralized zones. The average underground NI
43-101 compliant Measured and Indicated Mineral Resource grade for
the entire Goldboro Deposit is 6.18 g/t gold at a 2.0 g/t gold
cut-off. The Mineral Resource for the specific mine
areas targeted for the Bulk Sample predicted 11,274 tonnes of
Mineral Resource at an average undiluted grade of
3.81 g/t gold, capped at 80 g/t. A total of 13,022 tonnes of
mineralized material was mined and stockpiled on surface, at an
average diluted grade of 3.21 g/t gold based on grade control
samples capped at 80 g/t gold, out of which 9,785 tonnes at an
average diluted grade of 3.51 g/t gold were shipped to the Pine
Cove Mill in Newfoundland for
processing.
Five areas of development were completed on three levels
(Exhibit A) at mine elevations of 4965 (Level 1), 4930 (Level 2 W,
Level 2 E, Level 2 Ramp), and 4920 (Level 3 W and Level 3 E). New
development, in excellent ground conditions, included three drifts
off the existing cross cuts on Level 1 and Level 2 (Exhibit B) as
well as the creation of a newly developed ramp to Level 3 (Exhibit
C) with two additional drifts resulting in a total of 213 metres of
new development. A total of 86 drift rounds were blasted which
allowed for inspection, mapping, and sampling from the faces of the
development headings. Information was also collected from the faces
of 13 slot raise rounds during the development of the stopes.
Drifting was advanced using a single boom jumbo, typically with one
round blasted per 12-hour shift. Stoping was completed using a
long-hole method using both up-holes and down-holes. Blasted rock
was mucked using 1.5 and 2.0 cubic yard scoop trams, and then
loaded into a 7.0 cubic yard truck to haul to surface.
Development faces were geologically mapped, photographed, and
sampled. Chip and muck sampling was completed systematically to
determine average grade for each round. A total of 2,148 muck and
1,380 chip samples were collected, as well as drilling and sampling
of 518 test holes, and 132 long holes, in addition to quality
control samples.
Processing, Grade Reconciliation, and Gold Recovery
Anaconda shipped 9,785 tonnes of the mineralized material to the
Pine Cove Mill in Newfoundland for
processing, where the gold was extracted via a combination of
gravity recovery followed by sulphide flotation and cyanide
leaching. The mill recovered 610 ounces of gold from the gravity
concentration circuit, with an additional 360 ounces being
recovered through the flotation and leaching circuits, for a total
of 970 ounces of gold recovered and an overall recovery of 81%.
Concentrate from the gravity circuit was further cleaned through
the use of a shaker table and additional gravity concentration
processes to ultimately produce gold doré bars.
The recovery results reflect the limitations of the Pine Cove
Mill with respect to the processing of Goldboro material. The metallurgical test work
reported on July 9, 2019,
demonstrated high overall gold recoveries averaging 97% using
gravity processing followed by whole-ore
leaching.
Composite samples taken from key sampling points in the process,
including gold contained in tailings, were used in conjunction with
the actual gold recovered and milled tonnage to calculate an
average head grade of 3.81 g/t gold. The reconciled results from
the processing of the Bulk Sample material are as follows:

The calculated head grade from processing was 3.81 g/t gold, a
positive reconciliation of 8.5% compared to the average mine grade
of 3.51 g/t gold. The Bulk Sample results indicate that we have
achieved good reconciliation of the diluted material mined compared
to the block model, and the reconciliation of the calculated head
grade to the average mine grade indicates that the capping of 80
g/t gold is appropriate, with upside bias.
The gravity recovery compared well to bench scale testing
completed in 2019, as part of metallurgical testing done by Base
Metallurgical Laboratories Ltd., under supervision of Ausenco
Engineering Canada Inc., which is leading the Goldboro mineral processing plant design (see
news release dated July 9, 2019).
Technical Information, Quality Control, and Reporting
Protocols
All underground chip, muck, and sludge samples were shipped
daily to the contract assay lab at the Dufferin Mine, near
Sheet Harbour, Nova Scotia, where
they were analyzed for gold by fire assay. A total of 836 samples
(coarse reject material) assaying greater than 1.50 g/t gold were
shipped to Eastern Analytical Limited ("Eastern") in Springdale, NL for check analysis via metallic
screen fire assay. Quality control samples were systematically
inserted into each sample batch and consisted of two prepared
powdered gold standards (Certified Reference Material) and a
natural blank. Results were assessed for accuracy, precision, and
contamination on an ongoing basis.
Mill feed tonnages used in the sample processing reconciliation
were provided daily. The Company collected 6-hour composite samples
during the processing of the Bulk Sample, which were assayed by
Eastern. Daily composite samples were taken on feed and tail
streams for reconciliation purposes. Mill throughput for the
Bulk Sample was estimated based on the feed belt scale which is
calibrated monthly. All samples were sent out to an external
independent lab for preparation and assaying for both gold
and arsenic. Gold assays were obtained by screened metallics fire
assay. For all the other samples, gold assay was obtained by fire
assay AA finish or gravimetric finish.
Bulk Sample Gold Sales and Update on Statement of
Claim
Of the 970 ounces of gold produced, the Company has sold 903
ounces for gross proceeds of $1,773,000, which will be recorded as a credit
against the Goldboro exploration
and evaluation asset in the Company's statement of financial
position. The related processing costs at the Pine Cove Mill will
also be capitalized to the Goldboro asset on a proportionate basis. The
remaining ounces will be sold in 2020.
As reported on July 23, 2019, the
initial shipping company that Anaconda had engaged for the Bulk
Sample, NIL Group Limited ("NIL"), has filed a Statement of Claim
(the "Claim"), alleging that the Company is responsible for certain
additional costs in relation to the shipment. As a result, NIL had
served a warrant with respect to the approximately 1,000 tonnes
which were yet to be discharged from the barge at the time of
filing of the Claim. As disclosed as part of Anaconda's Q3 2019
financial reporting, the Company obtained a court order allowing it
to process the tonnes subject to the warrant, on condition that it
post the proportional gross revenue generated from said tonnes into
an escrow account with the Court, pending further legal
proceedings.
The Company continues to consider the Claim to be without merit
and on August 16, 2019, the Company
filed its Statement of Defense and Counterclaim against NIL, Newman
Investments Limited, a related company to NIL, as well as NIL's
principals, alleging, among other things, contractual breach,
negligent and/or fraudulent misrepresentation, and fraudulent
deceit. Statements of Defense to the Company's counterclaim have
not yet been filed.
