Mr. Robert Baldock reports
MONUMENT MINING EXPECTS NATIONAL INSTRUMENT 43-101 REPORT BY LATE NOVEMBER 2011 ON THE MENGAPUR POLYMETALLIC PROJECT, PAHANG STATE, MALAYSIA AND COMPLETES A POSITIVE IN-HOUSE DUE DILIGENCE STUDY
Monument Mining Ltd. has completed its technical due
diligence on the Mengapur project. A National Instrument 43-101-compliant technical report on the Mengapur polymetallic copper-sulphur-gold-silver project is expected to be filed under SEDAR in late November, 2011. The Mengapur project is located in the Pahang
state, Malaysia, 16 kilometres from the town of Sri Jaya and a major highway,
approximately 75 kilometres from the Malaysian port of Kuantan, and 130
kilometres from Monument's wholly owned Selinsing gold mine. The
company announced previously that it has signed a binding memorandum of
understanding with the owner of the Mengapur project in acquiring 70 per cent
of the Mengapur project, subject to due diligence, the board approval
and all other regulatory approval.
In October, 2011, the company engaged Snowden Mining Industry Consultants
to prepare an NI 43-101-compliant technical report to be entitled "NI
43-101 technical report, Monument Mining Ltd., Mengapur property,
Pahang state, Malaysia" and to be dated November, 2011. In preparing the Snowden report, Snowden has reviewed the 10-volume
study completed in 1990 by Normet Engineering Pty. Ltd., Australia,
and the company has received the results of such review. The
information in the historical study was a result of 10 years of work at
an estimated cost of approximately $40-million (U.S.) that included over
58,000 metres of diamond drilling. The exploration program was conducted in
the 1980s and was carried out by Malaysian Mining Corp., a
Malaysian government-owned corporation.
The historical study states a historical resource at the Mengapur
project for both oxide and sulphide material at 224,409,000 tonnes
averaging 6.54 per cent sulphur, 0.25 per cent Cu, 0.16 gram per tonne Au and 8.86 g/t Ag, or
0.597 per cent Cu equivalent at a 0.336-per-cent Cu cut-off grade (see attached table). The historical proven and probable sulphide reserve located
within the Lerchs Grossman optimized pit (SP6 design pit) in just zone
A at a 0.336-per-cent CuEq cut-off grade contains a total of 64.8 million
tonnes averaging 8.63 per cent sulphur, 0.27 per cent Cu, 0.21 g/t Au and 2.59 g/t
Ag at an approximate 1.5 waste/ore strip ratio (see attached table).
Both the resource and reserve calculations were conducted by James
Askew and Associates out of Perth, Australia, as part of the historical
study. The historical study does not clearly state whether the
reported reserve is included in the resource estimate, nor does it
discuss details of how indicated resources and probable reserves were
classified for the Mengapur deposit. The historical study identifies
that a proved or measured category required a minimum of 13 samples to
inform the block, but did not specify a maximum search distance or
number of drill holes used to support the classification. The James
Askew Associates resource report used 50 m east-west by 40 m north-south
by 10 m vertical blocks, subcelled to 25 m east-west by 20 m north-south
by 10 m vertical blocks with estimations done by individual rock type
using inverse distance squared methodology and no clearly identified
metal grade capping strategy.
The historical resource and reserve estimates reported in the historical
study are considered relevant because they provide an indication of the
mineral potential of the Mengapur project. The historical resource and
reserve estimates reported in the historical study use categories other
than those set out in NI 43-101 and therefore should not be considered
as mineral resources and mineral reserves as defined in the CIM
guidelines. A qualified person (as defined under NI 43-101) has not done sufficient work to classify the historical estimates
contained in this news release as current mineral resources or mineral
reserves and Monument is not treating the historical estimates as
current mineral resources or mineral reserves. Accordingly, the
historical resource and reserve estimates reported in the historical
study should not be relied upon. In order to bring the historical
Mengapur resources and reserves in the historical study up to current
CIM Guidelines and thereby compliant with NI 43-101, the following
items need to be addressed:
- The use of more current mining costs;
- The
use of three-year trailing average metal prices as of November, 2011;
- The confirmation of metal recoveries for the oxide and sulphide ores
using more modern and available reagents;
- The confirmation of the
classification of the mineral resources and reserves at the property;
- The conducting of additional drilling and assaying (including
twinned holes of previous drilling to confirm the historical drilling
work that includes currently acceptable quality assurance and quality
control programs, certified independent assay laboratories, and
appropriate geological supervision by a qualified person).
The operations plan in the historical study recommended a 23-year mine
life (operating 348 days per year) and using an 8,500-tonne-per-day Cu processing
plant operation. Under this plan, the pyrrhotite concentrate was going
to be roasted to produce 590,000 tpa of sulphuric acid which would be
converted to 203,000 tonnes per annum of P2O5 in the form of phosphoric acid. This is based on a mining rate of
753,424 tonnes per day (2.75 million tonnes per year) to produce about 30,500 tonnes of Cu concentrate and about 620,000 tonnes of pyrrhotite
concentrate per year over the 23-year mine life. The historical study
envisioned total employment at the mine at 489 workers.

Notes: Equivalent Cu is based on the following assumptions: recoveries
for Cu, Ag, Au and S of 76.6 per cent, 47 per cent, 48 per cent and
82 per cent, respectively; and commodity prices in U.S. dollars per
kilogram equal to $1.37 Cu, $4,107 Au; $65 Ag; nine cents S and a
combined mining and processing cost of $4.496 (U.S.) per tonne. The
historical reserve is based on the A, B and C zones. The disclosure
of historical reserves is not meant to imply that there is any current
economic viability. This would require completion of at least a
preliminary feasibility study.

The decision to further the acquisition of the Mengapur project is based
on a positive result of due diligence work conducted over the last
three months by representatives of a technical team comprising an
independent qualified person and non-independent mining professionals
working directly for the company. Included in the due diligence study
was a review of the land, environmental risks, the historical drill
hole data consisting of 198 diamond drill holes totalling over 58,000 m
conducted from 1983 to 1988, and a critical review of the historical
resources and reserves and mining plan included in the historical
study. In addition, five diamond drill holes totalling 1,161 metres
have been completed to date in the A zone historical reserve area to
help verify the previous work. Initial drilling results and assays
confirm the existence of the historically defined polymetallic
mineralization based on two twinned and three infill drill holes.
Drilling is in progress at the project under the supervision of Todd
Johnson, PE, and an on-site geological staff with three diamond drills to
help with continuing metallurgy studies.
An existing copper processing plant is at the site that has a capacity
of 500,000 tpa in its current configuration. The company is looking at
the feasibility of constructing a new Cu processing plant and a new
roaster at the Mengapur project site.
Other opportunities for the project that are being examined include: an
oxide leach operation to extract Au, Ag and potential Cu in the soils
that overlie the sulphide orebody; and Fe production (magnetite
concentration) from both the soils and the sulphide rock.
Todd Johnson, PE, MAusIMM, MSc, geological engineering and MSc,
geology, is the qualified person as defined under National Instrument
(NI) 43-101 who has reviewed and approved the technical information
summarized in this news release. Mr. Johnson is considered to be an
independent qualified person of Monument. He has visited the property,
and as part of the technical team, he monitored and reviewed the
project data during the due diligence period, and worked closely with
Snowden in November, 2011, on the Snowden report. In late November, 2011,
Monument expects to file on SEDAR the Snowden report, which will describe the historical mineral
resources and reserves discussed herein and included in the historical
study.
We seek Safe Harbor.
