Emgold Announces Successful Results from Its 2011 Core Drilling Program Stewart Property, B.C.
VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 02/01/12 -- Emgold Mining Corporation (TSX VENTURE: EMR)(OTCBB: EGMCF)(FRANKFURT: EML) ('Emgold' or the 'Company') is pleased to announce that it has completed the 2011 field exploration program ('2011 Program') for its Stewart Property, located near Salmo, British Columbia. The focus of the 2011 Program was to further delineate a molybdenum exploration target, the Stewart Moly Zone, which has been indentified from historic drilling on the property and from subsequent drilling by Emgold.
The 2011 Program consisted of 19 drill holes totaling 2,526 metres. Both high and low grade molybdenum mineralization was encountered in drilling, as well as other metals including gold. Emgold has also identified the presence of rhenium, one of the rarest elements in the Earth's crust. Rhenium is used as a catalyst in the production of lead-free, high-octane gasoline. It is also used in alloys for jet engines and in tungsten and molybdenum based alloys. Both gold and rhenium have potential to be important byproduct metals within the deposit if found in sufficient quantities.
Highlights of the 2011 Program include:
-- drill hole 11SM06 returned 58.65 metres averaging 0.198% MoS2, with
0.58% MoS2 over 0.9 metres;
-- drill hole 11SM07 returned 4.92 metres averaging 0.233% MoS2,with 0.98%
MoS2 over 0.6 metres;
-- drill hole 11SM12 returned 9.25 metres averaging 1.94% MoS2;
-- drill hole 11SM17 returned 1.03 metres of 0.98% MoS2; and
-- drill hole 11SM18 returned 1.87 metres of 0.56% MoS2.
In addition to molybdenum, gold was also encountered including,
-- drill hole 11SM01 returned 1.56 meters of 1.15 grams per tonne gold;
-- drill hole 11SM05 returned 2.50 meters of 1.17 grams per tonne gold and
1.5 meters of 3.93 gram per ton gold;
-- Drill hole 11SM08 returned 1.34 meters of 1.27 grams per tonne gold;
-- Drill hole 11SM10 returned 1.82 meters of 1.65 grams per tonne gold;
-- Drill hole 11SM12 returned 0.21 meters of 7.09 grams per tonne gold; and
-- Drill hole 11SM14 returned 1.30 meters of 1.65 grams per tonne gold.
Elevated values for rhenium returned from the 2011 core samples were, in most instances, closely related to areas of elevated molybdenum. Significant rhenium intersections include:
-- Hole 11SM06 where elevated Re values were returned from 14.02 metres
depth down to 191.1 metres in the drill hole, with up to 1,653 ppb over
1.61 metres; and
-- Hole 11SM17 returned the highest Re value of 2,204 ppb over 1.03 metres
within a string of elevated values from 163.17 to 186.2 metres depth
down the hole.
Details of the drill holes, including mineralization intercepts, are set forth in Table 1 below and Table 2 attached to this news release.
Historic Exploration of the Stewart Moly Zone by Emgold and Others
The Stewart Property (the 'Property'), located in the Nelson Mining District, is an attractive poly-metallic exploration property. It contains a variety of styles and types of mineralization, with targets identified in different areas within the Property. Targets include the Stewart Moly Zone, Arrow Tungsten Zone, Craigtown Gold Zone, and Free Silver Zone. The Property consists of 28 contiguous mineral tenures (claims) covering 5,789 hectares, all of which are 100% owned by Emgold.
Previous exploration of the Stewart Moly Zone has included geological mapping, soil and rock geochemistry, geophysics, trenching and drilling. The most extensive of those historic programs was conducted by Shell Canada Resources in 1980-1981 and Selco Inc., a division of BP Exploration Canada Limited, in 1983. The two companies were searching primarily for molybdenum and drilled 23 holes in the area (Sources: Turner, G.W., Assessment Report 7722, 1980; Turner, G.W., Assessment Report 10072, 1981; and Carpenter, T., Assessment Report 12,251, 1983 - reports available at B.C. Ministry of Mines ARIS website).
In 1980 Shell drilled three diamond drill holes and in 1981 another 16 diamond drill holes and defined a narrow, steep dipping podiform breccia zone based on four of those holes. Historic information available from the Shell program includes assessment and project reports, drill logs, assay laboratory reports and summaries of the sampling and assaying procedures.
Selco Inc. conducted extensive exploration on the property for metals, primarily molybdenum, between 1982 and 1984. In 1982 Selco did airborne EM and magnetics surveys and rock chip sampling, and in 1983 they continued with geological evaluations, further geochemical sampling, ground geophysics and drilling. Much of their work was on the Stewart Moly Zone.
Emgold acquired the Stewart Property in 2001 and continued evaluation of the Stewart Moly Zone in 2005 and 2007. Geochemical sampling, geophysics, trenching, and drilling programs were completed to check historic work and further assess the strong molybdenum and other mineralization in the area. The Company drilled eight holes in the area, two of which were twin holes adjacent to historic drilling. The results of the twin holes compared favorably to the original Shell drill holes (see Emgold's Nov. 28 and 29, 2005 and Nov. 28, 2007 press releases).
2011 Program Results for the Stewart Moly Zone by Emgold
The 2011 Program focused solely on the Stewart Moly Zone and drilling intersected granitic rocks along a contact with altered sediments. Molybdenite mineralization was encountered within brecciated granite and sediments with strong silicification and potassic alteration. The drill program was successful at further delineating the extents and content of the molybdenum mineralized body. The location, orientation, depth, and significant results from the 19 holes drilled in the 2011 Program are outlined in Tables 1 and 2.
All of the 2011 core drilling was conducted within an approximate 120 metre strike length along the mineralized structure of the Stewart Moly Zone. The drill hole locations and orientations are provided in the Table 1 below:

Mineralized drill hole intercepts are summarized in Table 2, attached to this release. The results show intercepts of high and low grade molybdenum mineralization, as well as the presence of gold and rhenium.
Emgold's geologists utilized a strict quality assurance plan during the exploration programs that included communication with contractors about the needs for appropriate quality assurance, procurement of supplies and services capable of delivering the desired level of quality, sample handling to ensure integrity, inspection and testing to ensure that all work met or exceeded quality criteria, using methods that reduced the potential for errors, proper training of staff, and statistical analysis that ensured quality criteria were met. The Company completed drill core logging and processing at its facility in Salmo, BC. Samples were shipped to Acme Analytical Laboratories ('Acme'), an independent assay laboratory, in Vancouver for analysis. Acme Vancouver is ISO 9001 Certified. The exploration program was supervised by Perry Grunenberg, P.Geo. He is a Qualified Person as defined in National Instrument 43-101.
The assay laboratory catalogued all samples, maintained complete chain of custody throughout the analytical process. All sample preparation was done at the laboratory by their staff following standard procedures. As part of their quality assurance, the laboratory incorporated assaying standards, test blanks, and duplicate analyses of samples, and included those results in final reports. The final signed reports completed the chain of custody process. Thus far, no factors of any kind have been encountered in sampling programs conducted by Emgold on the Stewart Property that could materially affect the accuracy or reliability of Emgold's sample data. All assay results to date have now been tabulated and reviewed.
Analysis of the Results
The Stewart Moly Zone is currently interpreted to be a breccia pipe, as previously interpreted from geologic modeling using MineSight® software. It is a mineralized block with variable shape. The mineralization is closely associated with a breccia structure with apparent length of approximately 200 metres and variable widths up to 80 metres. The true width is not known. It is exposed at ground surface, and historic drilling indicates depths of 150 metres to date. Potential exists to expand the mineralized zone in several directions and at depth.
The current density of drilling along the mineralized breccia body will now allow for 3-dimensional modeling to further assess the resource potential, as well as delineating areas that may indicate further extents to the mineralization. Emgold is currently focused on completing drill hole compilation and modeling with the objective of ultimately defining an NI 43-101 compliant molybdenum resource in the Stewart Moly Zone. Other potential accessory metals such as gold and rhenium will be modeled as part of this work.
Nickel based super-alloys, for use in jet engines, contain up to 6 percent rhenium, making jet engine construction the largest use for the element, with chemical industry catalytic uses being the next most important. It is widely used as filaments for mass spectrographs. Rhenium is also used as an electrical contact material. Because of low availability relative to demand, rhenium is among the most expensive industrial metals. The average rhenium North American Spot Metal Price (99.9% Re) on January 1, 2012 was US$4,359.64 per kilogram (source www.metalprices.com).
Drilling to date indicates the potential to define a resource that may be recovered by open pit and underground mining extraction. Future exploration at Stewart may consider exploration for other possible breccia pipes in the area, as breccia pipes can often occur in clusters. Potential also exists for a mineralized porphyry system at depth. Exploration may also consider gold and silver targets that have been previously identified on the Property.
Emgold is in the process of completing an Assessment Report for the 2011 Program. Emgold will then develop a plan and budget for its 2012 exploration program at Stewart. In December 2011, Emgold raised CDN$767,750 of flow through funds for exploration on its B.C. properties, Stewart and Rozan, in 2012.
David Watkinson, President and CEO of Emgold, stated, 'The Stewart Property represents a highly prospective exploration property with a variety of exciting targets. Emgold is currently focused on completing core drilling with the ultimate objective of defining an NI 43-101 compliant molybdenum resource in the Stewart Moly Zone to improve the value of the property. There are other gold and silver targets that also require additional exploration to assess their potential.'
