Afferro Mining Inc. - Encouraging DSO Metallurgy Results From Nkout
/NOT FOR DISTRIBUTION IN THE UNITED STATES OR FOR DISSEMINATION TO US NEWS
LONDON, UK, Dec. 17, 2012 /CNW/ - Afferro Mining Inc. ("Afferro", TSX-V & AIM:
AFF) announces encouraging results from the direct shipping ore ("DSO") bulk
metallurgical testing conducted on material from the Nkout project. Results
from the remaining bulk metallurgical testing are on track to be released in
-- Over 5 tonnes of potential DSO material tested from 12
representative holes across the Nkout deposit
-- Fines product achieved with a 63.4% iron grade and low
deleterious materials, using simple attrition scrubbing
-- Low-cost crushing implied due to the soft, incompetent rock
with a very low bond work index of 2.6kWhr/t
-- Simple crushing circuit expected: high throughput and low
-- Saprolite and magnetite bulk metallurgical testing expected to
be delivered in January 2013
-- Scale of testing sufficient to support pre-feasibility study
("PFS"), to commence in Q1 2013
Afferro's CEO, Luis da Silva, commented:
"The quality of the DSO we have identified at Nkout further enhances the
viability of the project and underlines our confidence in its continuing
development. This progress has been acknowledged by the Government of
Cameroon, which now classifies Nkout at "Project" level having been promoted
from "Exploration" level, highlighting its strategic importance to the Country.
"The testwork implies that the first stage of DSO production at Nkout should
be low-cost, with low capital intensity, yielding a high-grade product of
63.4% iron with low deleterious materials. This early, low-capex stage of
production will be examined in the PFS, commencing in Q1 2013. We look forward
to the remaining metallurgical results, to be released in January 2013."
Summary of DSO Metallurgical Testing and Results
Metallurgical testwork was completed on 12 PQ-size (4.6 inch outside diameter)
holes taken from across the DSO mineralisation identified at Nkout to date.
The total weight of these samples was in excess of 5 tonnes. This testwork is
sufficient to support the PFS, which is expected to commence in Q1 2013.
The physical test work suggests that the Nkout DSO material is relatively fine
and incompetent. After single-stage crushing, nearly 40% of the DSO material
was finer than 10mm. Bond impact crushing work index measurements averaged a
very low 2.6 kWhr/t. This suggests that the energy required for crushing
should be low, and that the simple crushing circuit should have high
throughput and low capital cost.
Each sample was subjected to drop-tower testing in order to estimate the
quantity of lump that could be produced from the Nkout DSO resource. Lump
production only averaged 10.6%, suggesting that it would not be feasible.
However, a single fines product from the operation will further simplify the
process flowsheet and reduce capital costs.
Attrition scrubbing testwork on samples of the fines product suggests that
this method could benefit the operation. Scrubbing was shown to be able to
increase the iron grade by approximately 4 percentage points to 63.4%. It also
reduced the alumina content from 3.5% to just over 2% and reduced silica
content from 7.6% to 4.3%. Additional planned scrubbing testwork is
anticipated to further improve the product quality. This testwork would target
finer crush sizes and also examine the feasibility of scrubbing high-grade
Saprolite samples to achieve DSO product quality.
