Future Production Forecasts

Peter Hambro Mining PLC
11 February 2008

11 February 2008

               Future production forecasts and project economics

Peter Hambro Mining PLC (the "Company") announces further details on its
production forecasts and projected economics to be included in the Analysts'
Workshop that it will conduct today.

These forecasts are based on internal expectations but are supported by the
Technical Report by Wardell Armstrong International ("WAI") that deals
specifically with the Company's production schedules. The full WAI Technical
Report can be found on the Company's website at


  • WAI has examined the operating and capital cost structure as projected by
    the Company for each of the principal assets and is satisfied that these
    budgets are appropriate and of the right order to allow proper development
    of each asset.
  • The Company expects that in 2010 its total attributable gold production,
    which includes its share from Joint Ventures, will be in the order of
    900,000oz and that it will exceed 1 million oz in 2011.
  • Based on exploration experience since 1994, the Company believes that the
    probability of maintaining exploration success sufficient to support such a
    production level beyond 2011 is high.  This belief is particularly supported
    by the fact that for certain assets that are not covered in the WAI report,
    such as Albyn, the Company has advanced production plans, as will be covered
    in the Workshop presentation.  These plans anticipate additional production
    of c.100,000oz in 2010 and 150,000oz in 2011.
  • The WAI Technical Report, which covers the Company's current fully
    evaluated assets, but excludes attributable production from Joint Ventures,
    forecasts production at the rate of c.835,000oz of gold per year in 2010 and
    c.755,000oz in 2011.
  • The principal differences between the Company's production forecasts and
    those of WAI are:

    o The Company's forecasts for Pokrovskiy are based upon improved recovery
      rates from primary ores achieved from recent changes to its processing 

    o The Company expects to maintain higher grades in 2010 and 2011 than
      those forecast by WAI. The Company's views are supported by exploration 
      success since the completion of the WAI Report.

    o The Company's forecasts include its share of production from joint
      ventures and from assets not included in the WAI forecasts.

  • The Company believes that its assumptions are appropriate, given recent
    technological improvements in its recovery process and its knowledge of its
    resource base.  In support of the Company's view, the WAI's report states

    o Opportunities exist to increase the reserve base, and thus the
      production schedule, over and above the numbers stated in the WAI's   

    o The Pioneer resource is significant in size and highly prospective for
      the discovery of additional ore columns and other zones of mineralisation.

Summary of production forecasts

For each project a comprehensive business planning, geological and engineering
analysis has been undertaken in order to estimate the expected production
profile. The Company's and WAI's estimates for the Group's attributable
production including attributable production from Joint Ventures are reflected
in the table below:

It should be noted that the comparison only covers assets included in the WAI
report and the Joint Ventures and not Albyn, Tokur and other Group assets.

Explanation of the differences.

The principal differences between the Company's internal production schedule and
that of WAI are as follows:

Pokrovskiy Rudnik

Recovery rates

The WAI model uses 86% recovery rates through the RIP plant taking into account
the fact that the Company is moving into deeper levels in the Pokrovskiy pit and
will start processing primary ore through the mill from 2008; as opposed to a
mixture of oxidized and primary ore in the previous years. During the last
several years the Company has carried out test metallurgical works on primary
material in order to improve the technological process and thus the recovery
rate at the plant.  The result of these works suggested that the Company should
use 91% recovery rates in its projections.  In addition, during the 4th quarter
of 2007, one of the milling circuits was converted to include a new
gravitational stage.  This enabled extraction of the most refractory material
which is then treated by intensive cyanidation.  As a result, in December and
January, 91% recovery rates were achieved while processing a composition of ore
containing 60% of primary material.  It is planned to introduce a gravitational
stage into the other two circuits at the plant during the first half of 2008 to
expand this capability as the pit deepens.

Additionally PHM took into account resources containing oxidized material at the
borders of the existing pit, which are under constant detailed exploration.  For
example, in 2007 50,000oz at 5.2g/t of such resources were converted by the
Group into reserve category C1. This work is ongoing.

Grades (reserves of high grade ore)

In its projections WAI reduced the head grades through the mill from c.4.0g/t in
2008 to 2.4g/t in 2011. This is due to the fact that, using JORC methodology,
some high grade resources of the deposit at the deeper levels of Pokrovskiy pit
are not included by the WAI production model. However, PHM's Micromine model,
calculated using a gold price of $750/oz, provides for sufficient high grade C2
material to sustain head grades of 3.8g/t until 2012.  Moreover drilling at the
deeper levels of Pokrovskiy ore body showed that high grade mineralization is
continuous even deeper to horizon 80 below sea level.



The Company's forecast uses 10% higher average grades at Pioneer than WAI's
forecast because WAI does not account for the uplift in the average grades to be
realised from high grade ore columns.  Recent bulk sample reconciliation from
Bakhmut (Apophasis 1) show that exploration drilling understated gold grades by
10-15%.  As an example, the reserve model forecast 8.39g/t whereas 9.32g/t was
mined.  These columns are presently not explored on a drill spacing close enough
to convert resources in these areas into reserves.  The Company's experience of
processing gold from ore columns of Bakhmut and Promezutochnaya zones during
metallurgical tests showed average uplift of 15% to the grades calculated purely
by exploration work.

Reserves of rich ore at Andreevskaya

WAI's model does not recognize the P1 resources from this extremely high grade
area whereas they are included in the Company's model.  The Company's rationale
for this is its long term experience of working at the deposit and the high
quality of the exploration work. Historically at this deposit the Group has had
a very high coefficient of translating P1 resources into C1 and C2 reserves.
For example, after the September 2007 data cut off for the WAI report, 350,000oz
of gold was converted from P1 into C2 categories.  This was not included in the
WAI report.  Similar works are ongoing.


At Malomir, WAI also excluded high grade P1 resources from its model.  However,
as a result of ongoing geological exploration works at Malomir part of the P1
resources - 250,000oz which were not included in WAI model - has been converted
into C1 and C2 reserves.  Currently there are still at least another 10 million
P1 tonnes of ore at Malomir at surface with average grades 3.0g/t, varying
between 1g/t and 15 g/t at ore intersections, potentially available for

Summary of WAI Report

Based on the existing production and exploration data, WAI reviewed the
Company's asset exploitation schedule to determine the suitability of its
projections.  WAI is of the opinion that PHM can expect to produce in the range
of 629k oz and 835k oz of gold per year, for the three years 2009 to 2011. This
determination is based on the current operational methodology and the current
estimated mineralisation grade and morphology.

WAI considers the Pioneer resource to be significant in size and highly
prospective for the discovery of additional ore columns and other zones of
mineralisation within the planned pit outlines as well as peripheral to the main
zones already defined. WAI also believes that opportunities do exist to increase
the reserve base and thus production schedule over and above the numbers stated
in the report. The production projections by the Company take into account part
of the additional higher grade ore columns' potential which was not taken into
account in the WAI projections.

Initial indications are that continued exploration around the Pokrovskiy mine
may delineate further reserves, but this has not been considered by WAI at this
time as part of their production schedule. In addition to the principal assets
of Pokrovsky, Pioneer, Malomir and Yamal, WAI reviewed some other projects
belonging to the Group that are at various stages of assessment and development
from grass-roots targets, to active placer gold producers and more advanced
drilling projects. Earlier development of other assets such as Albyn and Tokur
may, in addition to the further prospective reserves described above, provide in
the longer term additional sustainable production. None of these were taken into
account in either the PHM or the WAI production schedules.

Highlights of specific deposits as stated in WAI Report

Pokrovskiy Rudnik and Pokrovskiy Flanks

  • Current production rate at Pokrovskiy will continue until 2012.
  • Post 2012 production will move to a series of smaller deposits termed
    Pokrovskiy Flanks.
  • Capital expenditure requirements at Pokrovskiy are relatively low with
    USD$4.0M committed to geological exploration over the next 2 years and
    USD$18M budgeted for capital replacement of the mining fleet plus lifting of
    the tailings dam in 2012.

    life but will decrease to 1.7g/t Au by 2011.
  • Estimated mining costs at Pioneer are expected to be considerably lower
    than at Pokrovskiy due to reduced blending and re-handling of the ore and
    larger trucks and excavators used for waste mining.

   in grids of 600-100 x 80-40m.

•  Ore zones are open in all directions.

•  An extensive upper ore body overlaps two lower lying ones.

Chairman's comments

Peter Hambro, Executive Chairman of Peter Hambro Mining plc, commented:

"Our objective in holding a workshop for analysts who cover the Company is to
give them a chance to look in detail at the forecasts we are making, to question
the assumptions and to enable them to understand the reconciliation between
these and the independent report by WAI.  We hope that by doing this our
investors will gain a clearer picture of what it is that the Company owns and
thus of its future production possibilities.

With all mining companies the state of their geological knowledge changes often
and it is particularly gratifying that the changes we are experiencing are
highly positive.  This is particularly true at Pioneer and we have encouraging
results too from the existing Pokrovskiy mine.  At the newly acquired Albyn
deposit the initial exploration results are also very positive.  Armed with this
knowledge and our 13 years of experience on the ground, our geologists and
economic forecasters are confident in the production forecasts that we are
confirming today.

In light of this it is reassuring to have the confirmation of WAI of our
existing resources and that these are both significant in size and highly
prospective for the discovery of additional ore columns and other zones of

The Company's objective remains to match a steeply rising production profile
with an increasing effort to prove up our resource base; but above all to
produce profitable ounces of gold.

I have every confidence in the ability of our team to deliver what we have

Peter Hambro
