Project: Dugbe Shear Zone


Work has progressed on the Dugbe, Joe Village, Nemo Creek and Tiehnpo licences over the past year. These properties add up to over 2,000km2 in total, straddle the prominent regional-scale Dugbe Shear Zone, and make up a significant part of the so-called ‘Graphite Belt’ gold field. The Dugbe Shear Zone contains our Dugbe F Project with an NI 43-101 compliant Resource.

The Dugbe licence covers 450km2 and was awarded to Hummingbird in November 2005. It is 100% Hummingbird owned. This licence falls within the Dugbe Shear Zone which is a prominent northeast – southwest trending structure.

Approximately 1,400 soil samples have been taken on grid targets defined by satellite imagery. One of these is at Tuzon, lying some 2.5km to the east of this resource. At Tuzon, a large and well developed gold in soil anomaly was established, extending to a total of some 2.2km in strike length, with soil values exceeding 1 ppm Au in parts. Trenching at this prospect has shown major thicknesses of anomalous arsenic, together with several zones of gold mineralisation.

This excellent and strong gold anomaly contains a coincident arsenic anomaly, and provides an exciting target for outline drilling near to the initial deposit in the Dugbe F Project. This target is currently being drilled, with two drills active.

In addition to the drilling, over 2,000m of trenching has been completed on the Dugbe licence (mostly at Tuzon), with over 2,390 trench samples sent for assay, as well as approximately 200 other rock grab samples assayed.

Gold assay results from soils at Dugbe Block D have been highly encouraging and show an east-west trending gold in soil anomaly, with coincident arsenic in soils, measuring 1.4km across, with two distinct anomaly highs which are open to the west and east. A programme of 840m of trenching is underway across four north-south lines running perpendicular across the gold in soil anomaly.

At Dugbe Block B over 400 spur samples have been taken on low ridges which appear to be associated with silicified zones and abundant nearby artisanal workings. These zones broadly tie up with previous coincident gold/arsenic soil anomalies, and line up well with the regional east-north-east trend which is prevalent in this area. The gold in soil anomalies are currently being trenched as the next stage of work.

The licence covers 250 km2 and was awarded in October 2010. Hummingbird has an 80% interest in the licence. This licence also falls within the Dugbe Shear Zone adjoining the Dugbe licence to the east and has been resource drilled since February of this year. The results from drilling in this licence have been included in the resource upgrade.

Soil sampling to the west of the existing Resource has established very strong coincident gold/arsenic anomalies, with a number of samples over 1 ppm Au. This basically proves the westwards continuation of the Dugbe F mineralisation zone, and this has been confirmed by some 7,700m of drilling on Joe Village this year, of which 4,050m was complete by 31 May 2011. Over 3,000 drill samples have been taken and submitted for analysis from the Joe Village drilling during 2011.

The drilling has shown the mineralisation zone to extend westwards, as part of a folded anticlinal structure, with generally higher grades established than in last year’s drilling on the maiden Resource at Dugbe F.

Further gold/arsenic anomalies occur further west at Sackor. A total of 480 soil samples have been taken on two grids on Joe Village, with very positive results. In total over 3,200 soil samples have been taken on the Joe Village licence since it was acquired by Hummingbird in late 2010. The outlying parts of the Joe Village licence have been covered with some 270 stream sediment samples.

The licence covers 690km2 and was awarded in April 2010. Hummingbird has a 90% interest in the licence. This licence also falls in the Dugbe Shear Zone and adjoins the Dugbe licence.

This licence lies directly south of the Dugbe F Project, and is immediately south of the Dugbe Shear Zone. In early 2011 approximately 2,200 soil samples had been taken over three soil grids (named Hammerhead, Stingray and Tang), as well as regional soil sample lines, and showed coincident gold/arsenic soil anomalies with a strong east-north-east trend. These targets are planned to be trenched and scout-drilled in due course.

In addition to this, some 700 stream sediment samples have been taken regionally around the Nemo Creek licence, in order to provide a first pass coverage of additional new areas. Results of these samples are awaited.

This licence covers 665km2 and was awarded in July 2010. Hummingbird has a 90% interest in the licence. The licence also falls in the Dugbe Shear Zone.

This licence lies immediately east of the Dugbe licence, and forms an exciting eastwards extension along the Dugbe Shear Zone. Satellite imagery picked up at least three east-west ridge features, totalling over 10km in length, with abundant artisanal workings in streams draining off them. Hummingbird has taken some 120 stream sediment samples and mapped an extensive area, in order to help delineate specific targets within this area. Results of these samples have shown a number of anomalous zones which will be subjected to soil sampling in the weeks ahead.

Some 300 stream sediment samples have been taken in favourable areas around the Tiehnpo licence, for which results are awaited.

Project status

Dugbe F and Joe Village are at the Resource Drilling stage, whilst Nemo Creek and Tienhpo are currently undergoing Soil Sampling.
