African Consolidated Resources CEO Andrew Cranswick said, "We are making
rapid progress in implementing our development plan, since raising
approximately US$16m of new funding in November 2009.
ACR has planned
an aggressive 18-month drilling campaign and a target to bring four
projects up to a maiden JORC Resource status by December 2010, and to
increase the Resource base at the Giant and Pickstone gold mines which
already have a cumulative JORC resource of over 800,000 oz Au.
"Work since the publication of the Companys last technical report has
primarily focussed on progressing the Peerless Sulphide dumps towards
production and assessing the mining economics of the Peerless oxide cap,
infill Reverse Circulation drilling at Blue Rock to define a maiden JORC
Resource, and further surface sampling of the Chishanya rock phosphate
deposit.
Surface mapping and pitting has also defined drill targets at
the Cedric copper project.
"With a highly prospective multi mineral portfolio of projects, a
defined and active development plan, a strong treasury, near term
production from our gold tailings project and significant political
progress in Zimbabwe, highlighted by returning foreign investment, we
are extremely excited about the potential of ACR.
We have been
operating in Zimbabwe for many years and are positioned well to develop
the huge and recognised mineral potential of Zimbabwe."

DEVELOPMENT DRILLING
The Company has implemented an extensive drilling programme aimed at
advancing the value of it assets.
Drilling contracts totalling over
38,000m have this week been awarded to Zimbabwean drilling companies.
The summary programme for the next 12 months includes:
* 19,000m of Reverse Circulation (RC) drilling at the Gadzema
and Pickstone-Peerless projects (gold), and the Chishanya phosphate
project
* 9,500m of diamond drilling at Gadzema and Pickstone-Peerless
projects (gold), the Chishanya phosphate project, the Cedric copper
project, and the Snakes Head Platinum Group Elements (PGE) project
* 10,000m of exploration Rotary Air Blast (RAB) drilling on the
Chakari gold project and on other current greenfield projects as surface
results dictate
Gadzema Belt - gold
Blue Rock: The discovery is currently being assessed by RC infill
drilling to a depth of 150m over a strike of 600m, on 40m line spacing.
Since 1 December 2009, 2,400m has been drilled; no assays are available
due to the Christmas break but broad visible alteration logged downhole
is promising.
The remainder of the 4,000m programme should be completed
late February.
The Company expects to declare a maiden indicated JORC
resource in April 2010.
Giant Mine: A 2,000m diamond drilling programme is planned to commence
in March, aimed at extending the orebody at depth.
A further 3,000m of
infill RC drilling will follow the diamond programme targeting an
increase in the current JORC resource of 300,000oz.
Gadzema Belt Extensions: Encouraging RAB drill intersections over 5km
strike length between the Blue Rock and Giant Mine projects were
obtained in late 2009.
These areas will be followed up by 5,000m of RC
drilling in the first half of 2010.
Dependent on these results, a
further 3,000m will be drilled to determine a JORC resource before the
end of the year.
Pickstone-Peerless - gold
A 2,000m diamond drilling programme will be undertaken in the second
half of 2010, to test under the Peerless oxide gold resource, and to
investigate the Pickstone deeps.
Chisanya Carbonatite - phosphate
Channel chip sampling and in-house assaying using a Niton XRF analyser
has delineated extensive outcropping phosphate-rich ankerite rock.
The
latest analysis has, as reported on 1 December 2009, returned an average
P2O5 grade of 14%.
This was as a result of assaying by SGS
Laboratories, Johannesburg who returned grades P2O5 grades ranging
between 6-27% with a 2% cut off grade.
Further detailed channel chip
sampling and mapping is currently being undertaken to locate extensions
to the phosphatic rocks.
A 2,000m diamond drilling programme to test the phosphate mineralisation
to 200m depth will be initiated in March.
Dependant on these results a
5,000m RC infill drilling programme will commence in July, with a view
to producing an initial JORC resource by late Q4 2010.
Horseshoe Nickel
Pitting on a 50 to 100m grid is being planned to cover the 14 sq km
target area to determine the near surface nickel laterite resource with
a view to presenting a JORC resource before the end of the year.
Concurrent column leach metallurgical testing will be undertaken to
determine leach characteristics and recovery.
As previously announced,
preliminary metallurgical trials indicate good recoveries (>90%), short
residence times (<40 days), and low acid consumption.
EXPLORATION PROGRAMMES
Regional gold exploration
Chakari Gold: Soil sampling undertaken by ACR has outlined a number of
anomalous targets lying on splays of the well-mineralised Lily Shear
Zone, northwest of the major Dalny mine.
Further mapping, sampling and
RAB drilling will be conducted throughout 2010 to identify economic gold
mineralisation hosted in Archean metasediments and volcanics.
Regional Diamonds
A combination of ACRs historical diamond database and recent regional
exploration has defined two broad areas containing significant clusters
of kimberlite indicator minerals.
Commencing February, 10,000 line kilometres of aeromagnetics and
radiometrics will be flown over these areas to detect buried kimberlite
bodies.
Cedric Copper
Ongoing mapping has identified approximately 1,400m strike of surface
copper mineralisation over the old Cedric mine workings.
This area was
last explored in the 1960s, and lies in the Proterozoic Makonde
copperbelt.
Four diamond drillholes totalling 1,000m will commence late
Feb to test the down dip extensions to a depth of 150m.
Extension
drilling will be planned following the first phase results.
Perseverance Nickel
A heli-borne electromagnetic programme (VTEM system) is planned to cover
the 35km long nickel prospective horizon of the Perseverance Greenstone
Belt, commencing March.
Conductors will be identified and drill tested
as part of ongoing exploration during 2010.
Snakes Head PGE
It is proposed that the recently identified Fundumwi Block of this
northern subchamber of the Great Dyke will be drill tested once access
becomes available in the dry season.
The mineralogy and ultramafic
stratigraphy of the Fundumwi Block suggests that the PGE reefs in this
area may be higher grade than elsewhere in the chamber.
Four short
diamond holes are planned to intersect the P1 platinum reefs below the
oxide zone.
PEERLESS SULPHIDE DUMP - GOLD PLANT PROGRESS
In line with previous guidance, the ACR joint venture with TWP
Engineering (South Africa) is progressing towards production from the
Peerless Sulphide Dump (200,000t at 4.2 g/t) late May 2010.
Site works
have commenced, with the office block completed and transportable
accommodation and other site infrastructure under construction.
Contracts for earthmoving, onsite laboratories and tailings deposition
are underway.
Orders for equipment have been placed with vendors locally
and in South Africa, to be onsite in the first quarter.
Pilot scale metallurgical testing of the sulphide dump is complete with
gold recoveries in the range 65 - 70% observed.
This result is within
management expectations and is close to the target previously reported
of 73% less an allowance of 10% for operations scale losses as compared
with laboratory bench test conditions.
The pilot testing also
demonstrated significantly reduced reagent consumptions compared with
laboratory tests.
In addition to the high-grade sulphide dump, scoping studies have
commenced to investigate the economics of treating the Peerless oxide
cap through the same cyanide leach plant.
Initial Resource calculations on the Oxide and Transitional cap on the
Peerless Mine by Hellman and Schofield consultants, Perth, WA, returned
the following estimates (yet to be verified to JORC standard).
