Africa, besides being the cradle of civilization, is also host to
some of the world’s oldest and richest gold mines.
Ngwenya Mountain in
Swaziland hosts what is believed to be the world’s oldest mine, where early man
mined hematite and specularite over 42,000 years ago.
PMI Gold's properties are
all located in Ghana's Golden Triangle, an area in southwest Ghana with combined
current reserves and historical gold production of 170 million ounces. Gold has
been mined in Ghana for over 1000 years, and the famous AngloGold Ashanti Obuasi
mine has been in continuous production for 110 years.
PMI Gold now has interests
in 14 concessions in Ghana on the Asankrangwa and Ashanti Gold Belts, for a
total of 669 square kilometers.
In November 2006, PMI Gold
acquired the 89 square kilometre Abirem and Abore concessions - which cover the
former Obotan Mine operations of Resolute Mining of Perth – from the Ghanaian
government. Resolute ceased mining in 2002 after a total of 730,000 ounces of
gold were produced, with 590,000 ounces mined at 2.2 g/t gold from the Nkran
pit, and a further cumulative 140,000 ounces from the Adubiaso and Abore pits.
The price of gold, at then less than $320 per ounce, had rendered the remaining
known ore body uneconomical for further development.
Prior to completing the
mining at the Nkran pit, Resolute conducted extensive studies on the feasibility
of continuing mining from underground mineralization beneath the pit. Modeling
completed with a US$350 gold price suggested good potential for establishing an
underground operation.
PMI Gold believes there is
an exploration target of one to two million ounces of gold grading from 3.0 to
6.0 g/t below the Nkran pit based on previous deep drilling results and
projections to 400 m below the deepest intersection.
Resolute had previously
completed internal studies concerning underground mining scenarios to co-exist
with their surface mining. These preliminary studies were based on 58 drill
holes which intersected +3.0 g/t gold mineralized material below the level of
the pit.
Other results from these
studies indicate that:
• higher grades are
contained within lower grade envelopes and dilution won't be critical;
• screen fire assay retests
conducted on high grade intersections indicate a significant coarse gold
component to the high grade zones which may not be reflected in the current
assay database;
• metallurgical test work on
drill core composites from beneath the pit indicated recoveries of +96.6% on
leached concentrator tails with +75% of the gold reporting to the gravity
circuit; and that the assay database may be significantly under calling the
grades of the high grade lodes as the metallurgical leach tests returned a 52%
upgrade over the original screened 50 gram gold fire assays;
• modeling suggests that the
majority of the high grade mineralization is within structures which are
vertical with good continuity horizontally and vertically;
• the Western zone, also
referred to as the Galamsey Reef, remains open to the south and at depth. Two
major near vertical gold bearing structures have been partially outlined by the
previous drilling - called the Western and Eastern high-grade lodes. Most of the
deep diamond core drilling targeted these lodes under the south end of the pit.
Using a top assay cut of
30.0 g/t gold and estimating true widths to be 55% of the mineralized
intersection lengths, 30 drill intersections beneath the level of the pit exceed
22.5 gram gold per tonne metres.
These intersections have an
average indicated true width of 4.40 metres and weighted average gold grade of
10.02 g/t gold. The deepest down plunge intersection was 8.80 metres true width,
grading 8.15 g/t gold, and located 326 metres below the pit.
With gold above $600 per
ounce, this historic, non-43-101 compliant data certainly lends itself to the
compelling logic of focused development, and that is precisely what is underway
at the site.
According to company CEO
Douglas MacQuarrie, “Gold mineralization has been outlined to a depth of 425
metres below the pit with true widths varying from 20 to 45 metres. Within this
bulk mineralized zone there are significant high grade drill intersections
including 7.0 metres of 12.28 g/t Au; 8.0 metres of 10.00 g/t Au; 5.0 metres of
23.00 g/t Au; and 4.0m of 10.00 g/t Au. In order to prove the viability of this
zone for bulk or selective mining, further detailed drilling will be required,
preferably from underground drill stations as suggested by RSG Global in their
recent concept study report on the Nkran mineralization.”
Highlights from the drill
results announced last week include 44.5 m of 2.61 g/t gold in hole NK07-001
which tested the down dip extension of the Nkran pit orebody 330 m below the
base of the previously mined pit; and 2.7 m of 8.91 g/t gold in NK07-005
collared 170 m to the south of the southern end of the pit.
And if there is any doubt as
to the potential for an ‘elephantine’ sized orebody at Obotan, consider this:
If you were to draw a circle
120 km in radius from the center of the Obotan concession, it would enclose in
the neighborhood of 80 million ounces of as yet un-mined gold, with one deposit
measuring in excess of 10 million ounces gold, and the AngloGold Ashanti mine,
which still contains an estimated 25 million ounces of gold and is currently
under rehabilitation to permit mining to over 3 km in depth! Newmont,
Goldfields, GoldenStar, and RedBack all have operating mines and juniors Central
African Gold (Bibiani), Keegan (Bonte) and Perseus (Ayanfuri) are all defining
orebodies for near term production.
