BCGold Corp. Reports Bulk Sample Concentrate Grades Up To 6,485.8 g/t Gold (189.2 oz/ton) From Engineer Gold Mine
read pdfVancouver, British Columbia, December 14, 2011 (TSX-V: BCG and PINK SHEETS: BCGOF) -
BCGold Corp. (or the “Company”) is pleased to report partial assay results from its 2011 bulk sampling
and test milling program at the Engineer Gold Mine in northwestern British Columbia. The Company has
received assay results for 815 kg of Table Concentrate (reported below in Table 1) that was produced
while test milling six composite bulk samples mined from remnant portions of the Engineer and Double
Decker Veins above 5-Level, in some cases outside and adjacent to the currently stated mineral resource.
This material was previously categorized as waste material by conventional chip sampling and drilling.
Gold was recovered in up to three separate concentrates from the on-site mill’s recovery circuit for each
of the six bulk samples. The Company awaits assay results for approximately 190 kg of Sluice
Concentrate and approximately 5 kg of High-Grade Gold Stream Concentrate in order to estimate diluted
mining head grades for each bulk sample. These results are expected in January 2012.
Gold assay highlights from Engineer Vein Table Concentrate include the following:
- Bulk Sample 505-3B assayed 6,485.8 g/t Au (189.2 oz/t).
- Bulk Sample 505-3A assayed 1,324.1 g/t Au (38.6 oz/t).
- Bulk Sample 505-5 assayed 1,382.2 g/t Au (40.3 oz/t).

* Table Concentrate is a product of the finishing shaker table of a mill’s recovery circuit, where approximately 2% of the total rock mass is upgraded to a potentially marketable product. Table Concentrate is the largest by volume of the three concentrates collected by BCGold Corp. (Table, Sluice, and High-Grade Gold Stream) and is most-likely the lowest grade. By itself the Table Concentrate underestimates the contained amount of gold in the in-situ bulk sample and the grades from the other two gold concentrates are required to properly back calculate in-situ grades.
“We are very pleased with these preliminary bulk sample results from Engineer Mine,” states Brian P.
Fowler, P.Geo., President and CEO of BCGold Corp. “The results clearly indicate that substantial gold
occurs in portions of the Engineer and Double Decker Veins where conventional, smaller samples
obtained by drilling or chip sampling can grossly underestimate gold content. Management anticipates
that remaining concentrate assay results and resultant diluted mining head grade calculations will more
than justify additional exploration, mine de-watering, test mining and milling in 2012.”
Pending Sluice Concentrate Assays
As part of the test milling process, a sluice tray was inserted into the milling circuit to capture the coarse
gold fraction from the ball mill slurry prior to either being rejected by the 30 mesh screen deck or being
pumped to the triple deck Deister tables. Approximately 190 kg (wet) of Sluice Concentrate was collected
while processing the six bulk samples. The Sluice Concentrate is being processed by the Metallurgical
Division of Inspectorate Exploration and Mining Services Ltd. (“Inspectorate”). A decision to either
upgrade the Sluice Concentrate to a dore bar or sell to a smelter along with the Table Concentrate will be
made once assay results have been received.
Pending High-Grade Gold Stream Concentrate Assays
Approximately 5 kg of High-Grade Gold Stream was cut into a separate concentrate while processing
bulk sample 505-3B over the finishing shaker table. A 2 to 5 cm wide gold stream was observed and
collected at the finishing table while processing this sample. The 5 kg sample has been shipped to the
Metallurgical Division of Inspectorate to be processed into a gold-silver dore bar. A report of the final
weight and bullion fineness of the dore bar is expected in January 2012.
Wire Gold Specimens
In addition to gold recovered from the gravity separation mill as concentrate, approximately 14 kg of
high-grade roscoelite with >5% “wire” gold were recovered while mining bulk sample 505-5. These
samples were collected prior to being crushed at the mill and management believes their value as mineral
specimens is much greater than the actual gold content. Mineral specimen dealers are being contacted to
assist in marketing these samples.
Metallurgical Study
Gekko Systems of Ballarat, Australia has been contracted to conduct bench-scale gravity and leach
amenability test work in order to determine gravity recovery potential of the Engineer Mine mill feed.
The metallurgy samples have been shipped to Gekko and results are expected within the first three
months of 2012.

About the Engineer Mine
BCGold Corp. owns a 60% interest in the Engineer Mine property, with an option to earn a 100% interest.
Engineer Mine was a high-grade gold producer that came to peak production in the mid-1920s and ceased
operation in the early 1930s. More than 560 kg of gold and 278 kg of silver were officially produced at
realized grades exceeding 39 g/t Au and 20 g/t Ag, from high-grade epithermal quartz-carbonate veins on
six of eight mine levels.
There are more than 25 known veins on the property and only four have undergone limited production
and exploration to date. All veins remain open at depth and little exploration has been conducted deeper
than 200 metres below surface.
The Company consolidated its land position around Engineer Mine in 2010 by signing an option
agreement to acquire a 100% interest in the adjacent Gold Hill property. The 2,100 hectare Gold Hill
property includes the Happy Sullivan high-grade gold epithermal prospect and a 2.2 kilometre segment of
the highly prospective Shear Zone “B” structure.
BCGold Corp.’s 2011 exploration and bulk sampling program (see October 6, 2011 press release) is
Phase I of a two-phase, three-year, $10.2 million exploration and development program designed to
increase the mineral resource at Engineer Mine and take the property to near-term production.
