rounding area for possible new discoveries.
“Sedgman has significant experience oper-
ating in Botswana. This should assist MOD
in building community and landowner rela-
tionships and undertaking environmental and
permitting related studies that will be required
if feasibility studies confirm a viable under-
ground mining operation at Mahumo.”
Hanna is a geologist who was co-founder
and former MD of Western Areas, Australia’s
second largest underground miner. He leads
a team which includes Steve McGhee, MOD’s
Resources Director (he is also a co-founder
and Director of IMO), and Jacques Janse van
Rensburg, General Manager Exploration
(Africa).
MOD has tenements in Botswana extend-
ing over nearly 7 000 km

in the area between
Maun and Ghanzi. The Mahumo deposit, the
company’s main focus of interest, is located
approximately 100 km south-west of Boseto,
the only mine (although it is currently on care
and maintenance) to have been built so far in
the Kalahari Copperbelt.
A Stage One mineral resource estimate for
Mahumo of 2,7 Mt at 2,0 % copper and 50 g/t
silver was announced in March this year.
It is based on drilling completed by MOD in
2011/2012 and 2014/2015 along a 2,4 km
strike length at Mahumo to an average depth
of approximately 300 m. The resource remains
open below the current limit of drilling and
resource extension drilling (Stage Two) is due
to start shortly (subject to funding).
The Mahumo resource has a copper equiva-
lent grade of approximately 2,5 %, which MOD
believes is the highest grade for an announced
copper/silver resource in Botswana. The silver
grade of 50 g/t is particularly impressive and is
