VANCOUVER, Aug. 25, 2011 /CNW/ - Mr. Frank J. Basa reports:

Gold Bullion Development Corp. (TSXV:GBB) (OTCPINK:GBBFF) (the "Company"
or "Gold Bullion") announces that it has completed 6,842 m in 12 holes
of diamond drilling in its first drill campaign on the Castle Silver
property historic past-producing silver mine property located 85
kilometres northwest of the historic silver camp in Cobalt, Ontario.

Numerous strong calcite veins and vein systems were drilled and many of
these were independent of the existing mine workings. The best silver
intersection encountered is a 3.09m (10.138 feet) weighted interval of
6,476 g/t Ag (188.80 oz/ton Ag) in hole CA11-08 from 563.54 to 566.63 m
including a 0.45m (1.476 feet) interval of 40,944 g/t Ag (1193.70
oz/ton Ag) in a calcite-Co-Ag vein (not true width). Leaf silver was
common in the wall rock in the reported interval.

Gold Bullion's NQ drill program and drill core sampling, including the
quality assurance/quality control program, are supervised by D.
Robinson, P.Eng. and project geologist. Core from this drill campaign
was sent to Accurassay Laboratory in Timmins, Ontario, for sample
preparation and to their Thunder Bay laboratory for analysis. Silver
was assayed by fire assay with AA check with additional pulp and
metallics analysis done on samples where significant silver was
identified. Analytical accuracy and precision are monitored by the
analysis of reagent blanks and reference materials at the lab. Quality
control is further assured by the insertion of blind certified standard
reference material and blanks into the sample stream at regular
intervals by the geologist on site in order to independently assess
analytical accuracy

Five holes crossed the complete stratigraphic section of the shallow
dipping Nipissing diabase fulfilling one of the program objectives to
define the entire thickness of the diabase and detailed internal
stratigraphy. The apparent thickness varied from 230m to 365m. The
Nipissing diabase is considered the primary feature controlling the
emplacement of silver deposits.

The recently completed exploration program consisted of an orientation
IP geophysical survey and 12 diamond drill holes (6842m) designed to
test various targets including 4 IP targets as well as identify low
angle faults in proximity to the diabase. Using geophysics to detect
silver prospects has long been attempted but has proven difficult due
to silver being a perfect conductor. The success of this program has
led to the recommendation of follow-up down-the-hole EM and IP
geophysical surveys and further diamond drilling in several locations
based on interesting findings.

Gold Bullion is extremely happy with the results of this drill campaign
and is eagerly anticipating the next phase of exploration.
