VANCOUVER, British Columbia, Sept. 3, 2009 (GLOBE NEWSWIRE) -- Silverado Gold Mines Ltd. (OTCBB:SLGLF) (Frankfurt:SLGL) (www.silverado.com) (the "Company" or "Silverado"), is pleased to release the first results of the 2009 drill program from the Company's Nolan Creek property in Alaska. Click http://tinyurl.com/n7ka96 to see the August 26th background information news release.
Pictured in the diagrams below are the Solomon Shear Zone 'A Vein' Structure and the two primary areas of exploration in 2009, Workman's Bench and Pringle Bench. The 6,000 foot A to A' section on the diagram demonstrates the areas partially diamond core drilled from 2007 to 2009. Some 2009 assay results are listed herein and some are pending. Drilling continues.

Workman's Bench
In 2007 and 2008 mineralized vein-fault structures on Workman's Bench were first drilled and together with underground bulk sampling metallurgical work; the first probable mineral reserves were categorized (see Silverado's NI 43-101 Technical Report, Amended June 1, 2009 at www.silverado.com). The drilling completed during this period showed that nearly 70% of the probable mineral reserve occurs within the 'A Vein' Fault Zone.
From June 2009 to date a total of 2,660 feet of diamond core drilling was completed in nine (9) holes above the mid to southeastern part of the zone of probable reserves. Stibnite-quartz carbonate mineralization was encountered in eight (8) of the nine (9) holes. One hole was abandoned in a fault. The picture below shows a two foot wide zone of massive stibnite(1) (1.6 feet true thickness) from the 'A Vein' Zone in drill hole 09SH05, which is the thickest intersection of massive stibnite (antimony sulfide) encountered thus far.

Pringle Bench
At Pringle Bench in 2009, the mineralized vein-fault structures of the inferred mineral resource (see Silverado's NI 43-101 Technical Report, Amended June 1, 2009 at www.silverado.com) have been explored to date with a total of 1492 feet of core drilling in seven (7) holes. All drill holes intercepted stibnite quartz-carbonate mineralization as deep as 210 feet below surface. The inferred mineral resource shown in the diagram on page one is also disclosed in the NI 43-101 report referenced above.

Exploration on the Pringle Bench gold/antimony deposit northeast of Workman's Bench consisted of surface cleaning of mineralized zones and core drilling. The former revealed much about the textural elements of the vein (see picture immediately above). The most significant conclusions from the 2009 Nolan Creek exploration program to date are:
1) The main 'A' mineralized vein-fault at the Workman's Bench
gold/antimony deposit has been extended southeast of the probable
reserve previously documented there, thus adding to the potential
to increase resources on Workman's Bench.
2) Multiple stibnite-quartz carbonate mineralized zones have been
documented up to 180 feet below the inferred resources previously
known at the Pringle Bench gold/antimony deposit, thus increasing
resource potential on Pringle Bench as well. Mineralization is
open to depth and length on both zones. Silverado is awaiting
analytical results from mineralized drill intervals encountered
during the 2009 drill program which have been submitted for assay,
and will report them as they are received.
