GRAN COLOMBIA GOLD PROVIDES EXPLORATION UPDATE

TORONTO, March 6 /PRNewswire/ - Gran Colombia Gold Corp. (TSX: GCM) is pleased to announce exploration results from its ongoing diamond drilling programs in Colombia. Highlights include drilling at the Gran Colombia Project which encountered the depth extension of the Providencia Vein 250 metres down-dip from the deepest level of the mine, assaying 161 grams per tonne (g/t) gold over 0.4 metres or 64.5 g/t gold when diluted to one metre. In addition, drilling at the Segovia Gold property intercepted the depth extension of the target vein, grading 22.3 g/t gold and 15.9 g/t silver, including 0.11 metres at a grade of 63.4 g/t gold and 44 g/t silver.

Gran Colombia Project

To date, a total of 19 diamond drill holes totalling 6,836 metres have been drilled or are in progress, with assay results for eight holes, three of which intercepted the Providencia vein, indicating a down-dip extension of 250 metres below the 11 Level, currently the deepest mining level at this site. Gold grades within the vein ranged between 38.4 g/t gold and a high of 161 g/t gold, over widths of 10 to 60 centimetres. Gold grades ranged from 13.4 g/t gold to almost 65 g/t gold when diluted to one metre, which supports the high-grade character of the Providencia vein and the Gran Colombia district. In management's opinion these intercepts have the potential to define new ore blocks to be exploited in the short and medium-term.

Mazamorras Project

Initial results have been received for the upper part of the first hole, MAZ-1, drilled to test the Porphyry A Anomaly at the Mazamorras copper-gold prospect in Nariño Province. The hole, totalling 478 metres, was almost entirely within porphyry and intersected 478 metres of porphyry copper-style mineralization with an upper oxide zone followed by a zone of secondary copper enrichment, and passed through into primary porphyry mineralization. The Phase 1 target area is a 1.2 kilometres (km) by 2.0 km anomaly that is dominated by the presence of andesite porphyry with minor intercalations of dacite porphyry, with dominant quartz-sericite alteration overprinting earlier potassic alteration. The copper minerals are fine- to very fine-grained in the oxide zone, with chalcocite in the secondary zone and chalcopyrite in the primary zone. Magnetite is conspicuous throughout the mineralized interval, along with neotocite in the oxide zone.

Hole MAZ-2, located 340 metres northwest of MAZ-1 was completed to a depth of 400 metres. Hole MAZ-3 is in progress, 375 metres southwest of MAZ-2. Full details including assays will be released upon completion of the eight hole reconnaissance drill program.

Plans for Mazamorras into 2011 include three active drill rigs by April, 2011. The exploration budget for the project is $3.8 million, including additional more geophysical surveys, sampling and exploratory drilling.

Segovia Project

The Company has received results for ten drill holes, showing the extension of the Gran Colombia vein that assayed 71.6 g/t gold over 0.33 metres (diluted to one metre), as announced by the Company on January 13, 2011. Hole 10 intersected 63.4 g/t gold and 44 g/t silver over 0.1 metres at a depth of 220.7 metres (22.3 g/t gold and 15.9 g/t silver diluted to one metre).  The details are summarized below:

Providencia Project

Surface samples, collected inside the concession area as shown below, assayed results up to 14.7 g/t gold on an east-west vertical to sub-vertical structure located to the west side of the concession.  Initial diamond drilling results from hole PP02-11 encountered sub-economic grade gold mineralization. Additionally, a mineralized structure oriented NNE/vertical to sub-vertical mined by locals 100 metres to the north appears to continue to the south into the Providencia area.  The sample results appear in the table below:

The Company plans to start acquiring geophysics by mid-March 2011, with 74 km of IP and ground magnetics planned.

El Zancudo Project

Underground drilling is taking place at the La Independencia Level in order to identify vein extensions along strike and at depth. A 12,000-metre surface diamond drilling program is slated to commence in the second week of March.

QA, QC and Qualified Person

For all results except those relating to the Mazamorras Project, SGS de Peru S.A.C. (ISO 9002) in Medellin, Colombia prepared all samples which were assayed at their facility in Lima, Peru.  Mazamorras samples were sent to ALS-Chemex (ISO 9001:2000) in Quito, Ecuador for preparation and assaying.
