(TheNewswire)
Vancouver, BC – TheNewswire - February 8, 2023 - Hanstone Gold Corp. (TSX.V:HANS) (OTC:HANCF) (FRA:HGO) (the“ Company ” or “ Hanstone ”) is pleased to announce that ithas received preliminary metallurgical results from a 54.5-kilogrambulk sample of mineralized material from its Doc Property.
Analysis was conducted on a 54.5-kilogramrepresentative bulk sample collected from DOC22-Pit 2E, DOC22-Pit2.5E, and DOC22-Pit 3E. The tests were conducted by Sepro Laboratories(“Sepro”), a full-service metallurgical testing facility locatedin Langley, BC.
Highlights
Metallurgical testing achieved excellentrecovery from processing of mineralized material from the DocProperty.
-
Combined gravity concentration and cyanide leaching(gravity-leach) achieved overall gold recovery of 95.3%.
Head Assays
Calculated head grades ranged from 31.5 g/t to 34.8 g/tAu with a calculated average grade of 32.2 g/t Au and a direct headassay grade 33.6 g/t Au ( Table1 ).
Table 1: Head Grade Summary
Test Work Description | Method | Head Grade Au (g/t) |
Direct Head Assay | Assayed Grade | 33.6 |
Fine Gravity (4 stage) | Calculated Grade | 34.8 |
Gravity-Flotation | Calculated Grade | 33.3 |
Gravity-Leach | Calculated Grade | 31.5 |
The Direct Head Assay also returned values of 220 g/tAg, 1.93% Fe, 7.05% Pb, and 0.6% S.
Gravity Concentration
A 20 kg subsample was subjected to a 3-stage gravityconcentration test with intermediate grinding. The Falcon L40concentrates were panned to determine upgradability. The stage 3Falcon tailings were split into multiple subsamples for the followingtestwork:
-
Additional gravity concentration at a finer grind size(P80 of 45 microns).
-
Flotation using a standard gold-sulphideprocedure.
-
Cyanide leaching under standard leachconditions
Standard gravity recoverable gold (GRG) testworkdetermined that grinding to a P 80 of 78 microns achieved a gold recovery of 24.8%. Theconcentrates were high grade and amenable to further upgrading bypanning. Additional grinding down to a P 80 of 45 microns increased overall goldrecovery to 30.7%.
Flotation Test
The scoping flotation test was conducted on the stage 3Falcon tailings using a standard gold-sulphide procedure. Flotationtesting achieved a gold recovery of 70.5% and a silver recovery of63.7%. Flotation of the stage 3 gravity tailings (gravity-flotation)increased the overall gold recovery to 78.0%.
Cyanide Leaching Test
Cyanide leaching on stage-3 gravity tailings(gravity-leach) increased overall gold recovery to 95.3%. Therelatively high dissolution of the gold content, as compared with theflotation recovery results, indicates while the valuable constituentsare likely locked with the silicate gangue, there is high surface areaavailability for cyanide leaching.
Summary
Overall flowsheet test results are summarised in Table 2 .
Table 2: Test Result Summary
Flowsheet Description | P 80 (µm) | Au Recovery (%) |
Standard Gravity (3-stage) | 78 | 24.8 |
Fine Gravity (4-stage) | 45 | 30.7 |
Gravity-Flotation | 78 | 78.0 |
Gravity-Leach | 78 | 95.3 |

The Company also reports the issue of 250,000 optionsto officers exercisable at $0.10, which will expire in 5 years fromthe date of issuance, pursuant to the option plan.
Andre Douchane, Executive Chairman commented: “Giventhe grade of this material and the way it reacts with gravitytreatment followed by cyanidation appears similar to Franco Nevada’sMidas Mine. At Midas, a very low percentage of the gold was capturedby gravity and the remainder was recovered from a cyanide circuit.Very exciting developments and will certainly be a main focus goingforward.”
