MANHATTAN, NV--(Marketwire - 10/27/09) - Royal Standard
Minerals, Inc. (OTC.BB:RYSMF - News) has completed a study of its
Pinon and Darkstar properties in Elko County, Nevada and has
identified a number of new drill targets that have potential to be
additive to the current near surface gold-silver resources at Pinon
and Darkstar and for deep, underground, "new" gold resources. The
development of new drill targets during this phase of study
concentrated on those areas in close proximity to the measured near
surface oxide gold-silver deposits to include the Pinon Property -
Main Zone and North Pod and the Darkstar deposits. (There projects
are currently under evaluation for near term development as an open
pit heap leach operation by RYSMF).
The regional exploration within the Carlin Trend over the past
20 years has resulted in the discovery of deeper (underground) high
grade (0.4-1 opt) multimillion ounce gold deposits such as the Deep
Star, Meikle and Rain-extension gold deposits. These structurally
controlled deposits are frequently associated with or in close
proximity to near surface open pit gold deposits. On the RYSMF
property position there is geo-technical support from drilling,
geologic, geochemical and geophysical data that continued
exploration may result in the discovery of larger deposits that are
not exposed at the surface.
The initial exploration effort on the RYSMF land package will
focus on northwest, north and northeasterly fault controls to help
guide the development and testing of targets where previous drill
data and down dip down plunge extensions of existing deposits
indicates the presence of significant persistent gold
mineralization to depths greater than 1,500+ feet. A second phase
of the effort will involve a "step out" drilling program to explore
for concealed underground deposits along strike and down dip within
prospective untested fault zones on the RSM property position.
Pinon Area NW Fault and Breccia Pipe Trend-Southern Property
Block
A large "Rain-type" collapse breccia occurs 1,000 feet south of
the Pinion shallow oxide gold resource currently under evaluation
for possible production. In the (multi-million ounce) Rain gold
district, the occurrence of structurally controlled collapse
breccias are key elements in the development of open space for the
introduction of gold deposition and alteration events associated
with west-northwest trending fault zones. The collapse breccias
occur within fault zones that can contain deep mineralization
developed within the Devils Gate Limestone.
On the RYSMF property, the first of these collapse breccia
structures was identified through drilling returning deep gold
mineralization that requires additional exploration. The most
significant mineralized section indicated to date in this breccia
contains 110' of 0.078 opt gold from 580-690 feet, 175 feet of 0.14
opt from 740'-915' drill depth. Other drill holes returned 30' of
0.110 opt gold from 525-555 feet, and to 0.25 opt gold in narrow
fault controlled zones within the Devils Gate Limestone. Past
drilling tested only the northeastern portion of the feature. RYSMF
proposes to continue testing this structure for gold deposits that
are not exposed at the surface within the Devils Gate
Limestone.
RYSMF geophysical data has defined these collapse breccias as
circular pipe-like features approximately 2,000 feet in diameter,
the northern portion of which has been partially drill tested and
is gold mineralized. A second circular geophysical feature on the
RSM property position occurs 2,000 feet WNW of the first anomaly
and is also about 2,000 feet in diameter and has never been drill
tested. RSM proposes to test this second circular geophysical
feature and the WNW fault zone that connects the collapse breccias.
These anomalies represent attractive deep Rain-type gold
targets.
Darkstar Project
The Darkstar gold-silver deposit is located approximately one
mile east of the Pinon Main zone deposit in Elko County, Nevada.
Darkstar is a near surface, potential open pit mineable low grade
(0.027 opt) gold/silver system. The property development area has a
defined antiformal shaped, 300 foot thick, zone of generally lower
grade gold that is somewhat bedding conformable gold
mineralization. This low grade zone is characterized by abundant
hydrothermal injection breccias and pervasive silicification.
Higher grades (0.15 opt) occur in the weakly and sporadically in
the weakly silicified hanging and footwall rocks. Higher gold
grades are also hosted by crosscutting, high angle fault zones.
Preliminary metallurgical testing results on drill cuttings
indicate that this gold mineralization is amenable to direct
cyanidation treatment indicate gold recoveries ranged from 75% to
91.3% with a mean average recovery of 81.8% in 96 hours leaching.
Gold recovery rates were fairly rapid and extraction and was
substantially completed from 6 to 24 hours. Cyanide consumption was
low. The preliminary metallurgical tests are very encouraging in
regard to gold recovery and the rate of recovery of gold and silver
which is similar to and better than the Pinon test results.
The Darkstar mineralization is open on strike toward the north
and south of the currently know deposit. The metallurgical
characteristics of this mineralization are considered to be
compatable with the Pinon main zone deposits oxide gold-silver
mineralization and can considered to be additive to the Pinon
deposits for a centrally located heap leach recovery system.
The Company plans to drill test these targets in conjunction
with the drilling program designed to expand the near surface
measured gold oxide deposits currently under evaluation for
possible development as soon as possible.
