Mumbwa gold test shows promise
BLACKTHORN Resources Limited (BTR) has said the final gold test for
phase five drilling project in Mumbwa in Central Province is showing
positive results.
BTR managing director Scott Lowe said the company was pleased to see
some positive gold results from the tests.
BTR is an Australian-based resources company unearthing value
from a diverse portfolio of base and precious metal projects in
Africa.
In Zambia, the Mumbwa copper-gold producing company is exploring for large iron oxide
copper-gold deposits, similar to the style of mineralisation found at
the Olympic Dam and Prominent Hill mines in South Australia, and
Ernest Henry mine in Queensland.
Drilling has delineated an initial Inferred Mineral Resource of 87
million tonnes at 0.94 per cent copper at the Kitumba Prospect.
According to a statement posted on the company website, the phase five
drilling programme commenced in August 2011 and was completed after
drilling 21 holes for a total of 10,934.51 metres.
“We are very pleased to see some positive gold results, especially
which these results confirm further shallow supergene enrichment.
“The current ground work and analysis, together with our future
exploration plans bring us into a truly exciting phase for the Mumbwa
project,” Mr Lowe said.
The statement said true-widths were not quoted as further work
was required to determine the geometry of the mineralisation.
It was considered that these elevated grades were a result of supergene
enrichment and
proximity to structures, most notably the North-East trending Kankamu Fault.
Zones of relative gold concentration were also observed in some drill holes.
The statement said that in most holes, the narrow zones of relative
gold enrichment occurred within a broad halo of low-level gold
mineralisation.
Further understanding of the gold and copper mineralised zones and
their geometries would be gained from geological modelling and the
updated mineral resource estimate currently in progress
