Progress Report on Exploration programme
Highlights
* RESOURCE STATEMENT - Results from the Phase II
drilling programme carried out in the first half of
year 2000 take the resource defined to date on the
highly prospective Esquel Gold Project to in excess
of 2.45 million ounces of gold and 5.4 million ounces
of silver.
* GEOPHYSICAL SURVEY - The Induced Polarisation (I.P).
and Resistivity survey carried out over the southern
core area of the Cordon de Esquel has produced a large
quantity of anomalous resistive features with trends
similar to several of the known silicified structures
and has shown the possible extension of the Galadriel
Sur vein towards the Elena and Julia vein systems.
* LAND - The acquisition of the Willemanco and Leleque
exploration concessions completes the consolidation of
M.E.D.'s land position on the highly prospective
Cordon de Esquel and Cordon Leleque bringing the total
area held in the Esquel region to excess of 140000
hectares.
* PHASE III DRILLING - Preparations are on target to
commence the Phase III 12000 metre drilling programme
in early September aimed at extending the two major
resources Galadriel Sur and Julia together with
exploration drilling on the newly defined
I.P.Resistivity targets.
Bill Humphries, Managing Director of Brancote Holdings
PLC said:
'The excellent drilling and exploration success achieved
over the past 18 months has established the presence of a
world class gold resource at Esquel.'
Resource Statement
Further to the resource statement published in February
2000, Minera El Desquite (MED) requested Pincock Allen &
Holt (PAH) a leading mine engineering consulting company
based in Denver, Colorado, to produce a resource estimate
incorporating both the Phase I, 1999 and Phase II, 2000
drilling programme. These programmes comprise
approximately 22000 metres and have defined resources in
five deposits namely: Galadriel, Galadriel Sur, Elena
Norte, Elena Sur and Julia.
The resource summary reported by PAH is:

A full report describing the work performed by PAH is
being prepared. The scope of work included a review of
the geology and data collection methods used by MED,
including mapping, drilling, sampling, assaying, quality
control procedures and data base compilation.
The PAH resource statement will serve as an independent
report prepared by a Competent Person as defined by the
Council of Mining and Metallurgical institution in the
UK. PAH has been responsible for the preparation of the
resource estimate contained on this announcement and has
more than five years experience in the estimation,
assessment and evaluation of mineral resources on ore
reserves which is relevant to the style of mineralisation
under consideration.
Resource definition, as estimated by PAH is attached as
an appendix to this report.

Highlights of PAH's resource estimate are:
* 90% of the resource is in the measured and indicated
category.
* The Galadriel Sur deposit contains 1.33 million
ounces of gold of which 1.2 million ounces have a
grade in excess of 14 grams/tonnes.
Both Galadriel Sur and Julia are open at depth with
continuing high grade gold and widths. To date, Galadriel
Sur has been drilled to an average of 125 metres down
dip, along 500 metres of strike and remains open to the
south.
Julia has been drilled to an average of 70 metres down
dip, along 250 metres of strike and remains open to the
north.
Geophysical Survey
Quantac Geofisica Argentina has reported on the Induced
Polarisation, Resistivity and Total Field Ground Magnetic
Surveys conducted over the southern area of the Cordon De
Esquel, centred on the Galadriel Sur and Elena systems.
Electrical resistivity proved to be the most effective
measured geophysical parameter to detect and delineate
silicified structures in the survey area.
The gradient surveys produced a large quantity of
anomalously resistive features with similar trends to
several of the known silicified structures.
A comparison between mapped veins (Galadriel Sur) and
resistive lineaments shows a high correlation.
Three 'Real' sections conducted over the high area
between the veins Galadriel and Julia indicate a trend of
much stronger resistivity anomalies and shows possible
extension of the Galadriel Sur vein under a tuff unit.
In addition there are many similar resistive lineaments
and broader resistive areas that do not correspond to
known veins, in particular, data indicates that at least
two resistive trends occur at depth in the vicinity of
the Galadriel Sur vein.
Land
Negotiations have been successfully concluded with Minera
Andes for the 'option to purchase' its exploration
'cateos' adjacent to the Cordon De Esquel. This
acquisition gives MED strategic control over the entire
70Km long range from Cordon Leleque in the north to the
Sierra Colorada in the south.

Phase III Drilling
Preparation is well advanced to commence the Phase III
drilling and exploration programmes in early September.
Major Drilling has been awarded the contract to supply
two 650 multipurpose (Diamond and R.C.) drill rigs, one
of which has already been mobilised to site with the
second due by 10th September. Contingencies are in place
for a third and larger drill if required.
Drilling will target down dip and along strike extension
of the two main resources Galadriel Sur and Julia, where
drilling in the last programme finished in high grade
(+30g/t Au).
Exploration drilling will target the highly prospective
Antonia and Ungoliant vein systems together with the new
I.P. resistivity interpreted structures to the south of
and adjacent to Galadriel Sur.
This programme is scheduled for completion by mid
December.
APPENDIX
Resource Definition
The following are definitions of terms relating to
various categories of resources used by PAH in this
report.
Resource: A concentration of naturally occurring solid,
liquid or gaseous material in or on the Earth's crust in
such form and amount that economic extraction of a
commodity from the concentration is currently or
potentially feasible. Location, grade, quality and
quantity are known or estimated from specific geological
evidence.
To be classified as a resource, there must not only be
some evidence that the concentration of materials exists,
but there must be sufficient information available to
estimate the quantity of material.
To reflect varying degrees of geological certainty,
resources can be subdivided into measured, indicated, and
inferred.
Measured: Quantity is computed from dimensions revealed
in outcrops, trenches, workings, or drill holes; grade
and/or quality are computed from the results of detailed
sampling. The sites for inspection, sampling and
measurements are spaced so closely and the geological
character is so well defined that size, shape, depth, and
mineral content of the resource are well established.
Indicated: Quantity and grade and/or quality are computed
from information similar to that used for measured
resources, but the sites for inspection, sampling, and
measurements are further apart or are otherwise less
adequately spaced. The degree of assurance, although
lower than measured resources, is high enough to assume
geological continuity between points of observation.
Inferred: Estimates are based on geological evidence and
assumed continuity in which there is less confidence than
for measured and/or indicated resources. Inferred
resources may or may not be supported by samples or
measurements but the inference must be supported by
reasonable geo-scientific (geological, geochemical,
geophysical, or other) data.
