African Gold Group Finalizes Comprehensive Metallurgical Test Work Returning Significant Improvements in Gold Recovery to 96%...
05 May 2020 - 2:05PM
African Gold Group, Inc. (TSX-V: AGG) (“
AGG” or
the “
Company”) is pleased to provide an update
from the comprehensive metallurgical test work programme,
undertaken as part of the definitive feasibility study (the
“
DFS”).
Metallurgical Testing Highlights:
- Confirmed the potential for consistent gold recovery of
96% across all ore types, up from 80% previously
- Simplified, compact process plant flowsheet, minimizes
the requirement for expensive and long lead process
equipment
- Tried and tested process flowsheet, simple to operate
and cost effective, in terms of capital and operating
costs
- Flexibility to exceed 100,000oz per year of output as
determined by input feed grade
- Extremely low hardness and abrasiveness of ore,
resulting in very low power requirement and reduced wear on liners
and mill media
- Low deleterious elements resulting in low reagent use
and low operating cost
- Highly flexible process able to treat varying ore
grades and ore types with no significant increase in reagent
consumption
- No need for oxygen enhanced sparging in the leach
tanks, eliminating the requirement for an oxygen
plant
“The Phase 2 metallurgical test work has
concluded a very comprehensive, but fast-tracked test work
programme on time and under budget,” comments Danny Callow, Chief
Operating Officer of the Company. “The focus for the DFS is to
develop a low capital, low maintenance, robust and flexible process
route, whilst ensuring that comprehensive analysis of composite ore
from the open pit zone was undertaken. I am very pleased that the
test work has proven the processability of our Kobada Gold Project
ore, through a proven process technology, consistent with most
oxide operations in West Africa. This is a major step towards
finalising the DFS by Q2-2020 and completing the process plant
design.”
As a component of the DFS, the Company completed
a definitive metallurgical analysis on composite ore samples across
the mineralized zones. As an update to the 24th February 2020
announcement, African Gold Group Finalizes Optimised Flowsheet, the
Company is pleased to confirm that the Phase 2 programme has been
completed on time and under budget.
Phase 1 involved investigating the optimum
treatment route by assessing possible gold recovery methods. Phase
2 metallurgical test work involved optimizing the processing
flowsheet to obtain the parameters for maximum gold recovery.
Variability comminution and recovery test work was also conducted
to establish the degree of variability within the ore zones with
respect to their metallurgical response using the optimum
conditions determined in Phase 2.
The test work was completed by Maelgywn Mineral
Services (“MMS”) in South Africa, who was retained by SENET, the
Company’s project manager for the DFS. Upon the completion of the
comprehensive metallurgical test work programme, SENET will
finalize the design of the ore processing plant for the Kobada Gold
Project.
“We are very pleased with the outcome of the
test work for the Kobada Gold Project,” commented Phil Bundo,
SENET’s Process Director. ”The results show exceptional gold
recoveries with very low leach residence times, and very low
reagent consumptions. This allows us to fast-track the design for a
typical West African oxide process plant, which will save us
significant engineering design time. The results of the test work
show that the process plant will be capable of handling all oxide
ore type blends, whilst maintaining a high gold recovery and low
operating costs.”
The Company is aiming to deliver the DFS in
Q2-2020. Despite the delays due to the lockdowns and access
restrictions due to the current COVID-19 pandemic, the Company has
continued to work remotely to complete the study within the
committed timelines. Total costs of the Company for the DFS are
expected to be delivered under budget.
