Duncastle Announces 90% Gold Recovery in Metallurgical Tests for its Yankee-Dundee Project
26 May 2010 - 11:30PM
Marketwired
Duncastle Gold Corp. (TSX VENTURE: DUN)(FRANKFURT: 5D3) (the
"Company") reported today results of preliminary metallurgical
tests on drill core from its past-producing Yankee-Dundee mine
project. The project is located three kilometres northeast of Ymir
and 50 km from Trail, in southeastern British Columbia.
Preliminary metallurgical tests were completed to assess the
production potential of the project. Overall recoveries of 90.3%
gold, 95.0% silver, 86.2% lead and 96.8% zinc were achieved using
conventional flotation techniques. The results confirm the
amenability of the ore to mineral recovery via conventional
flotation. Additional recovery is possible with process
optimization due to the preliminary scoping nature of the work.
Testing was conducted by Kemetco Research of Richmond BC on a
composite sample created from available drill cores from holes
YD09-39, -40, -45, -46, and -47. The test sample head grade, which
is not necessarily representative of potential ore grade from the
project, was 4.06g/t Au, 57.9g/t Ag, 1.31% Pb and 4.58% Zn.
Good separation of lead and zinc was achieved which may be
important for potential concentrate sales. In addition, gold and
silver report primarily to the lead concentrate, which is also a
benefit in terms of expected smelter credits.
Historically, a single flotation stage was used to produce a
lead concentrate with gold and silver values, as shown in video
footage of the Yankee Girl mill from the 1940s, available on
Duncastle's website at duncastlegoldcorp.com.
Work on the project to date has included preliminary inspection
of old mine workings, 7,700 meters of diamond drilling in 48 holes,
airborne geophysics, geological prospecting and mapping, and a
preliminary archaeological report. The Company has defined a gold-
and silver-enriched sulphide mineralization zone called the Yankee
Girl West. This zone lies above the historic 1235 adit along the
western projection of the Yankee Girl structure and extends
approximately 285 metres along strike with a vertical depth of 280
metres. The Yankee Girl West zone is one of five exploration target
areas of similar or greater dimension, which Duncastle has
identified at and around the historic workings of the Yankee Girl
mine.
Recommended work for 2010 includes continued surface exploration
work and underground exploration and drilling of the Yankee Girl
structure and Bonus vein via the Wildhorse adit, a 1.4km adit that
ends at the Yankee Girl structure 110 meters below the historic
mine. Historic chip sampling in 1961 within the workings at the
Cayzor raise partially defined a zone approximately 200 feet (61 m)
in height (approximately down-dip along the mineralized structure)
containing wall samples averaging 8.68 g/t Au, 74.4 g/t Ag, 2.4 per
cent Pb and 4.48 per cent Zn over an average width of 1.31
metres.
Note that historic data provided has not been independently
confirmed by the company, is not N.I. 43-101 compliant and
therefore cannot be relied upon.
Duncastle Gold Corp. is a Vancouver based gold exploration
company with mineral claims covering or surrounding past producing
mines in two historic BC districts. In Southeast BC Duncastle is
targeting high-grade gold-silver-lead-zinc veins at the former
Yankee-Dundee mine, 50km from the smelter at Trail, BC. In
Northwest BC the Company's holdings cover a 10 km long magnetic
anomaly, previous workings, and high-grade veins on its Porphyry
Creek project. Duncastle has assembled contiguous claim blocks
totaling more than 170 sq km in these two productive regions,
targeted for gold and copper exploration.
As part of the Manex Resource Group, Duncastle benefits from
shared expertise in corporate finance, public company
administration, investor relations, and technical and geological
services provided for six public companies. Since its formation in
1997, the companies within the Manex Group have raised over C$250
million in exploration financing.
