VANCOUVER, BC, July 15, 2021 /CNW/ - Kootenay Silver Inc.
(TSXV: KTN) (the "Company" or "Kootenay") is pleased to
announce that Blue Coast Research Ltd. has been contracted to
conduct metallurgical testing on Kootenay's 100% owned La Negra
silver discovery, situated 7 km north of the Company's Promontorio
Resource located in the state of
The purpose of the metallurgical work (the "Program") is to
further investigate the best recovery process for La Negra
mineralization. Results from the Program will be used by the
Company to advance La Negra along the path towards an initial
mineral resource estimate and a preliminary economic assessment
Work will include:
- Sample characterization including QEMSACN mineralogy.
- Bond Ball Work Index test and grind calibration testing.
- Cyanidation Testwork including kinetic bottle roll and coarse
kinetic bottle roll tests.
- Flotation Testwork including bench scale rougher floatation
tests and a locked cycle test.
The above tests will help determine the preferred process for
recovery of La Negra silver mineralization, whether it be whole ore
leaching, leaching of a floatation concentrate or the production
and sale of a lead concentrate.
Previous Metallurgical Testing
Earlier metallurgical work conducted on La Negra by Kappes
Cassiday and Associates (KCA) and McClelland Laboratories Inc.
indicates very good potential for high silver recoveries.
The work completed by KCA showed leach recoveries in bottle roll
tests ranging from 70 to 90% with an average of 81% testing head
grades ranging from 62 to 242 gpt silver. Rougher floatation tests
indicated recoveries of 85 to 98% with head grades testing 66 to
143 gpt silver.
The McClelland Laboratories work indicated leach recoveries in
bottle roll tests ranging from 78 to 96.5%, averaging 86.7%, and
that mineralization is amenable to whole ore milling/cyanidation
treatment at 80% passing a feed size of 75 micrometers. Head grades
of samples used ranged from 73 to 247 gpt silver.
The Company looks forward to Blue Coast beginning their
evaluation of La Negra to further elucidate the potential that this
About La Negra High Grade Silver Discovery and Promontorio
La Negra, situated 7 kilometers north of the Promontorio
Resource, is a high-grade silver discovery which the Company
believes has the potential to become a low strip, open pit mining
operation. To date, 95 drill holes totaling approximately 17,000
meters have been completed with most intercepts returning
widespread silver mineralization from surface to a vertical depth
of over 300 meters.
Previous drill highlights include:
Hole 21-14 (See November 26,
2014 News Release)
- 200 m of 156 gpt Ag with 0.1 gpt
Au including 50 m of 420 gpt Ag with
0.18 gpt Au and 1337 gpt Ag with 0.47 gpt Au over 6 m.
Hole 5-14 (See October 15,
2014 News Release)
- 119 m of 91 gpt Ag including 183
gpt Ag over 40 m and 367 Ag gpt with
0.11 gpt Au over 14 m.
Hole 43-16 (See October 25,
2016 News Release)
- 44.5 m of 363 gpt Ag and 0.12 gpt
Au including 720 gpt Ag and 0.13 gpt Au over 19 m.
Promontorio is a large bulk tonnage silver resource that
currently hosts an estimated 44.5 million tonnes containing 92
million ounces of silver equivalent in the Measured & Indicated
categories grading 64.3 gpt silver equivalent and 14.6 million
tonnes containing 24.3 million ounces of silver equivalent in the
Inferred category grading 52 gpt silver equivalent.
NI 43-101 Compliant Silver Resource
The mineral estimate on Promontorio effective date March 31, 2013 (See May
14, 2013 news release) contains a combined Measured and
Indicated silver resource of 92,428,000 silver equivalent ounces
(39.9M oz's Ag, 508K oz's Au, 394.8M lb's Pb, 462.2M lb's Zn). In addition to the measured and
indicated silver resources, there are an additional 26,814,000
silver equivalent ounces in the Inferred category (12.8M oz's Ag, 147 oz's Au, 99.5M lb's Pb, 109.1M lb's Zn). Measured and Indicated resources
include open pit resources of 44,504,000 tonnes grading an average
of 64.32 gpt silver equivalent (27.77 gpt Ag, 0.35 gpt Au and 0.87%
Pb+Zn) and measured and indicated resources outside of the open pit
of 215,000 tonnes grading an average of 56.96 gpt silver equivalent
(22.89 gpt Ag, 0.28 gpt Au and 0.95% Pb+Zn). Inferred resources
include open pit resources of 14,564,000 tonnes grading an average
of 51.95 gpt silver equivalent (24.95 gpt Ag, 0.28 gpt Au and 0.59%
Pb+Zn) and inferred resources outside of the open pit of 1,265,000
tonnes grading an average of 61.17 gpt silver equivalent (26.57 gpt
Ag, 0.37 gpt Au and 0.74% Pb+Zn).
