Minco Gold Expands Mineralization at Shajinba and Baimashi Gold Zones, Yejiaba Property
31.03.2012 | Marketwire
VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 03/30/12 -- Minco Gold Corporation (the "Company" or "Minco Gold") (TSX: MMM) (NYSE Amex: MGH) (FRANKFURT: MI5) announces the results of its 2011 exploration program at Shajinba and Baimashi zones on the Company's 100% owned Yejiaba property, part of the Longnan Project, located in Gansu Province, China.The 2011 exploration program, designed to further test the gold mineralization zone discovered in 2010, was comprised of an initial drilling program at the Shajinba Gold Zone and a trenching program at the Baimashi Gold Zone, located only 3.0km away within the same structural and metallogenic trend. The results are encouraging, including the discovery of the new Baimashi gold zone, identifying the Yejiaba property as a target for future exploration. The Company is planning an exploration program including 3000m of drilling, 3000m of tunneling and surface exploration in 2012.
Highlights of the 2011 program:
A. Shajinba Zone
Drilling:
Drilling totaled 2,829.02 metres, covering an area of 1000m by 400m. Drill hole spacing ranged from 250m to 400m, depths ranged from 288.03m to 501.4m, targeting two zones trenched in 2009 and 2010: Targeted zones were gold mineralized, coinciding with surface trace of a thrust fault, gold-in-soil anomaly, and a poly-metallic mineralized zone. Drill results returned lower gold values than surface trenching, but provided verification of the structural interpretation based on surface work and geophysical surveys and discovery of several significant mineralized intersections at depth.
Drill hole SJB-003A: in an area with no surfical signs of mineralization, due to conglomerate cover, intersected a wide fault zone comprised of black carbonaceous phyllite and tectonic gouge with numerous dykes of porphyry granite to quartz diorite, a portion of which averaged 0.13g/t Au over 43.56 metres. Additional drilling in the vicinity may lead to a wide ore-grade zone of mineralization.
Drill hole SJB-005: within poly-metallic mineralization, intersected a pure hematite vein in massive limestone. Iron content averaged 61.5% over 2.29 m. The vein was traced on surface for 200 metres at similar grade and width. The drill intersection doubles its strike extension to 400 metres. The vein is open down-dip and along strike to the East.
The following table provides more details on results of drilling completed at the Shajinba Zone in 2011.

Induced Polarization (IP):
Continuous and distinctive IP anomalies were tested within three trenches at the Shajinba Zone. Two 80m spaced trenches returned the following results:
- 0.59 g/t Au over 6.6 m;
- 0.20 g/t Au over 6.0 m.
The IP anomaly extends for further 800 metres and remains untested.
B. Baimashi Zone
Trenching:
The Baimashi gold-antimony zone covers an area of 3 km by 1 km, located 3.0 km west from the Shajinba zone. It possesses numerous occurrences of gold and antimony, clustered in four Zones, hosted in massive limestone and calcareous phyllite. Widely spread grab samples returned gold values between 5.0 Au g/t to 50.0 Au g/t and antimony content was up to 15.0%. Mineralized intersections in the trenches were sampled with 5cm deep by 10cm wide and generally 1m long channel samples.
Zone 1 Significant Values:
- 3.62 g/t Au over 6.4 m;
- 4.41 g/t Au over 2.0 m;
- 2.26 g/t Au over 1.2 m, and
- 0.53 g/t Au over 6.0 m.
The zone extends for 500 metres and has been tested with six trenches.
Zone 2 Significant Values:
- 11.82 g/t Au over 3.5 m.
The zone is 1.0 km long and was tested with 12 trenches but gold content in trenches is generally less than 1.0 g/t Au.
The company has commissioned the preparation of NI 43-101 report on the Yejiaba Property.
Mr. Wayne Spilsbury, MAIG, FAusIMM, has reviewed this news release and is the "Qualified Person" responsible for verification and quality assurance of the company's exploration data and analytical results.
