Britannia Mining has confirmed that the company will embark on 2300m core drilling at Nthale Hill. 

Nthale Hill is one of 6 areas that have shown high magnetic anomalies within a 20 sq km area that was explored by the company during 2010.  From the trenching and geological mapping, a preliminary mineralisation estimate of 4.6 million tonnes was given for Nthale Hill area  - considering an ore body which is 300 m X 100 m and a depth of 30 m using a SG of 5.2 for haematite (Chiwandama Geo Consult.). The approximate tonnage for the additional 5 areas is still to be considered.

An estimation of the total iron ore reserves at Nthale Hill and surrounding areas can be given with greater confidence once detailed drilling has been carried out.

Figure 1: shows the area proposed for Phase 1 drilling. 

A magnetic survey has verified the extent of the Nthale iron ore body and possible iron bands on the eastern side. From the completed pitting and trenching, there is a very good correlation between the magnetic anomaly and areas underlain by the iron ore.  The magnetic survey further confirmed that the iron ore body dips in a westerly direction. To intersect the whole ore body, drilling activity shall commence on the western side of the hill.
