NV Gold Corporation Reports Positive Metallurgical Results at Afgan/Kobeh
27 April 2011 - 11:00PM
Marketwired
NV Gold Corporation (TSX VENTURE: NVX) (the "Company") is reporting
positive results from its initial bottle roll cyanidation test of
drill cuttings from its 100%-owned Afgan/Kobeh Project located in
Eureka County, Nevada. Test results for the near-surface oxide
mineralization indicate the project will be amenable to low-cost
cyanide heap-leaching. Highlights of the study results are given.
62 samples were selected from RC drill cuttings collected during
the 2010 drill program performed by the Company. The samples were
tested by Kappes, Cassiday and Associates (KCA) of Reno,
Nevada.
A total of sixty-two (62) bottle roll tests were completed on
as-received reject material during Phases I and II. All leach tests
were run for a period of forty-eight (48) hours with solution
sampling performed at 6, 24 and 48 hours. The tests utilized 1,000
grams of as-received (uncrushed) material slurried with 1,500
milliliters of tap water. Sodium cyanide was added and maintained
at 5 grams per liter of solution. The pH of the solution was
maintained at 11.0 with the addition of hydrated lime Ca(OH)2. The
following recoveries were reported by rock type and general grade
of gold:
-- 79.5 per cent for the Webb Fm. Material low-mid (less than 2.9 gpt)
grade,
-- 77.1 per cent for the Webb Fm. Material high (greater than 3.0 gpt)
grade;
-- 72.8 per cent for the Devil's Gate Ls Fm. Material low-mid (less than
2.9 gpt) grade,
-- 81 per cent for the Devil's Gate Ls Fm. Material high (greater than 3.0
gpt) grade;
-- Gold recovery rates were fairly rapid, results were obtained in 48 hours
of leaching.
These bottle roll tests give a good indication that cyanidation
will likely work at Afgan, and that heap leaching might be
possible. While additional work in the form of column tests will be
required prior to feasibility analysis, NV Gold President and CEO
John E. Watson stated, "These metallurgical results are very
positive. It appears that we will have the option of heap leach
processing at Afgan, with the attendant low capital and operating
costs. Heap leaching is a low-cost mining and recovery technique
commonly used in Nevada to recover gold from near-surface oxide
gold ores."
John Watson also said, "As we approach a preliminary economic
assessment of the project, we plan to continue to expand and
upgrade the resources with further drilling." With several untested
drill targets and extensions of known mineralization, there is good
potential to increase the current NI 43-101 resource. The company
will carry out a 2,000+ meter program during July and August,
designed to increase and upgrade the resources as well as initiate
a preliminary economic assessment by year-end.
The Afgan Project has excellent potential to host an open pit
gold operation utilizing the excellent infrastructure in place in
northeastern Nevada. Afgan is located approximately 45 kilometers
northwest of the town of Eureka.

Caution Regarding Forward-Looking Statements - This news release
contains certain forward-looking statements, including statements
regarding the resource at the Afgan/Kobeh project being amenable to
heap-leaching, the expansion and upgrading of existing resources,
the initiation of a preliminary economic assessment by the Company
and the potential of the Afgan/Kobeh project to host an open pit
gold operation. These statements are subject to a number of risks
and uncertainties. Actual results may differ materially from
results contemplated by the forward-looking statements. Factors
that could cause actual results to differ materially from those in
the forward-looking statements include the risk that cyanidation
may not achieve acceptable recovery rates on other parts of the
resource or that these recovery rates may not be able to be
replicated in a commercial scale operation, that additional
exploration may not expand or upgrade the resource, that the
Company may not pursue a preliminary economic assessment due to
disappointing results or financial conditions, that the projected
economics of the Afgan/Kobeh project will not be sufficient
profitable to warrant commencing production, the uncertainty of
continuity of observed mineralization assumed in mineral resource
estimates, particularly inferred resources, changes in metal
prices, changes in the availability of funding for mineral
exploration and development, unanticipated changes in key
management personnel and general economic conditions. When relying
on forward-looking statements to make decisions, investors and
others should carefully consider the foregoing factors and other
uncertainties and should not place undue reliance on such
forward-looking statements. The Company does not undertake to
update any forward-looking statements, oral or written, made by
itself or on its behalf.
