Project: Dugbe 1 Project

The Dugbe Shear Zone area consists of 2000 square kilometres in central eastern Liberia, lying some 40km northeast of the coastal town of Greenville. The Dugbe 1 Project is underlain by Birimian geology, making it highly prospective for gold, and is currently Hummingbird’s most advanced project, with over 38,000m of drilling and a 3.8 Moz gold resource. 1.8 Moz is from the Dugbe F Resource and a further 2 Moz was discovered 2.6km to the east as a Maiden Resource at Tuzon. Drilling is ongoing at Tuzon to expand this Resource. The Global Resource of 3.8 Moz is within truckable distance and forms the basis of the Dugbe 1 Project which is moving into development stage. There are a number of other anomalies within Dugbe 1 including Sackor which is 4km west of Dugbe F and has recently returned positive trench results. A scout drill programme is planned there.

The gold zone is hosted in sheared quartz biotite pyroxene schist within a garnet bearing alteration halo. The geological model is a 3 km long, continuous gold zone ranging in thickness from 5m to 40m, with the thickest zone outcropping at surface and pinching and swelling along strike as well as downdip. The gold zone strikes northeast and for the most part dips at 25-30 degrees to the southeast, with the southern part of the zone dipping shallow to the south and the area between Anomalies B and C dipping shallow to the northeast. The change in dip suggests a gentle open folding of the gold zone following the foliation trend.

Initial drilling at Dugbe F focused on the southern part of a 4.8 km long, northeast trending gold in soil anomaly (>30ppb Au). A continuation of the zone west into Hummingbird’s Joe Village concession has also been drilled and resulted in an NI43-101 compliant 1.8M oz gold resource. Drilling is currently focused 2.6km east of the Dugbe F Resource, in the Tuzon area, where strong gold-in-soil anomalies occur over 2.2km on a north-northeast strike. The first 43 drill holes here have resulted in an NI43-101 compliant resource of 2.05M oz gold resource. The deposit is open in several directions and drilling in continuing in the area along with trenching programmes. Strong gold-in-soil anomalies in Blocks B and D are being followed up with extensive trenching programmes in both areas.

Project status

Highlights

  • 3,817,000oz Au Resource
  • Consistent and even distribution of gold grades
  • Deposit is near surface, likely to have low waste: ore strip ratio on commencement of mining
  • Gradual increase in grades and decrease in tonnage with increased cut off grades
  • Full team of geologists on site
