Primary Metals Reports Gold Results at Quinta/Banjas Gold
Property
======================================================================
Primary Metals Inc. ("Primary" or "Company") is pleased to report
results of underground sampling programs at the Banjas and Serra da
Quinta projects located on the Company's Quinta/Banjas Gold Property
(the "Property") in Portugal. The Quinta/Banjas exploration concession
covers 44 square kilometres and is located some 20 kilometres to the
east of the major city of Porto.
Previous Exploration
The Banjas and Serra da Quinta projects were explored by Bureau de
Recherches Geologiques et Mini�res ("BRGM") and the Portuguese State
entity Empresa de Desenvolvimento Mineiro ("EDM") at the beginning of
the 1990s. More recently, from 1998 to 2003, Connary Minerals PLC
("Connary"), a subsidiary of Minmet PLC, completed extensive
exploration over the area. The Company has obtained the data related to
these exploration programs from the Portuguese Instituto de Inovac�o e
Tecnologia ("INETI") and is in the process of reviewing and confirming
the data produced by them. An important part of the confirmation
process has been underground channel sampling in both the Banjas and
Serra da Quinta mines.
Gold mineralisation in saddle reefs and quartz veins
The Banjas project is located on a major NNW-SSE regional structural
feature, the Valongo Anticline, and is positioned on the northeast limb
of the structure, which dips at about 15� to the northwest. Po�o Romano
(another gold occurrence within the concession) is at the northern end
of the structure. Gold mineralisation at Banjas is observed to be
hosted in stacked, saddle reef style, gold-enriched black argillic
lodes associated with quartz veining. These lodes are narrow, shallow
dipping and plunge gently to the northwest. The gold mineralisation
within them is associated with sulphides as pyrite and arsenopyrite
disseminated in clay and quartz.
At Serra da Quinta, gold mineralisation is associated with quartz veins
and silicified zones. These zones are related to a shear that is
parallel to a two-mica Hercynian granite contact with Silurian schists.
To the Northeast, the prospect is underlain by granite which hosts a
50-100 metre wide zone in which gold mineralisation is associated with
sulphides. Serra da Quinta lies 7 kilometres to the north east of the
Banjas project.
Confirmation sampling of High Grade gold mineralisation at Banjas
At the beginning of the 20th century, and sporadically up until 1938,
the argillic lodes were mined at Banjas for gold. The Company has
undertaken an underground sampling program at Banjas to confirm gold
grades noted by Connary and BRGM from channel samples taken
perpendicular to the flat lying vein structure at intervals of
approximately one metre along the stope faces from two stopes
(designated Stope A and Stope B by the Company).
Stope A
The face length of the Stope A working is approximately 14.5 metres.
The average value of assays from 15 samples in Stope A was reported by
BRGM as 11.91 grams per tonne ("g/t") gold across 0.61 metres along the
length of the working (14.5 metres). Values ranged from 1.3 g/t gold
over 0.6 metres to a high of 47.1 g/t gold over 0.6 metres.
The Company undertook channel sampling in Stope A, taking 4
confirmation samples at 3.0 metre to 4.0 metre intervals along the
face, to confirm assay values recorded by BRGM and Connary. The value
of these samples ranged from 1.78 g/t gold over 0.6 metres to 19.48 g/t
gold over 0.6 metres.
The average value of the samples taken by the Company in Stope A were
11.42 g/t gold over 0.60 metres. A top cut or maximum value for gold
assays of 60.0 g/t gold was applied to the calculation. The values
obtained by the Company compare favourably with those recorded by
Connary and BRGM.
Stope B
In the area designated as Stope B, approximately 25 metres to the south
west of Stope A, the face length is approximately 15 metres. The
average value of assays from 13 samples taken along the stope face (15
metres) was reported by BRGM as 36.88 g/t gold across 0.67 metres along
the length of the stope. Values ranged from 3.1 g/t gold over 0.65
metres to a high of 464.0 g/t gold over 0.6 metres.
The Company undertook channel sampling in Stope B, taking 5
confirmation samples at 3.0 metre to 4.0 metre intervals along the
stope face. The value of these samples ranged from 28.96 g/t gold over
0.6 metres to 346.93 g/t gold over 0.6 meters.
The average value of the samples taken by the Company in Stope B were
42.23 g/t gold over 0.69 metres. A top cut of 60.0 g/t gold was applied
to the calculation. These values, although slightly lower, compare
favourably with those recorded by Connary and BRGM
Other Workings
The Company also undertook check sampling of other workings that
exposed the flat lying vein structure in close proximity to Stopes A
and B. These values along with the comparative grades between the
Company sampling and the prior sampling are shown in the following
table:
Serra da Quinta
The Company has also undertaken confirmation sampling at the Serra da
Quinta project, which lies some 7.0 kilometres to the north of Banjas.
A series of 11 check samples was taken from an exploration adit where
previous sampling by Connary Minerals had returned encouraging gold
grades.
The samples were taken perpendicular to two distinct sub horizontal
structures, believed to be separated by a horizontal distance of
approximately 10 metres. The results of the original and confirmation
sampling follow (all assay values were top cut to 60 g/t gold):
.. The average grade of the four samples taken by Connary on the
structure #1 was 13.18 g/t gold across a width of 0.88 metres.
.. The Company's confirmation sampling of the structure #1 returned
assay values of 20.00 g/t across 0.88 metres.
.. The average grade of the five samples taken by Connary on the
structure #2 was 30.58 g/t gold across a width of 0.86 metres.
.. The Company's confirmation sampling of the structure #2 returned
assay values of 29.89 g/t across 0.86 metres.
The sample results are tabulated below:
The Drill Program
In addition, the Company has undertaken a diamond drilling program
which commenced in the fall of 2006 and was completed in May 2007. At
Po�o Romano, the program consisted of four drill holes totalling 641.70
metres. The holes were targeted at favourable geological features and
geochemical anomalies. In addition, 13 core drill holes were drilled at
the Banjas project from the underground workings for a total program of
555.80 metres. At Serra da Quinta, 44 percussive drill holes were
completed for a total of 1,477 metres. Core and cuttings from the
mineralized zones have been sampled and sent for assay. Final assay
results of this program are awaited and will be reported when all
results are available.
Quality Control and Quality Assurance
Sample preparation and analytical work is undertaken at an accredited
assay laboratory, OMAC Labs Ltd., in County Galway, Ireland, using
standard industry practices and conventional atomic absorption and fire
assay methods for gold (Au 4, gravity finish) and silver. Samples
believed to contain higher gold grades are assayed by process Au 9
(Screen Metallic). Base metal analysis is carried out using Aqua Regia
Digestion and Flame AA finish. For quality control purposes, analytical
standards with known metal values were included with the Company's
samples and show acceptable reproducibility. In addition, duplicate
analyses on selected drill samples will be carried out by a second
independent assay laboratory.
"We are very pleased with the results of the confirmation sampling,"
said Lewis Black, Chairman of the Company. "It is apparent that there
are structures containing high grade gold at the Banjas project and we
hope to be able to show these structures continue to the Po�o Romano
project some 3,000 metres to the northeast. Confirmation of the
extension is the primary objective of the drilling program. Our task is
to now extend the knowledge of those structures along the limb of the
major anticline with a view to defining an economic deposit. At Serra
da Quinta, the gold grades are again encouraging and we await the
results of the recently completed drill program to determine if the
project has the ability to match the Company's development criteria."
Primary Metals owns a 100 percent interest in the Panasqueira tungsten
mine in Portugal and is currently producing wolframite concentrates
containing some 100,000 MTUs of tungsten trioxide per annum with
further improvements underway. The Panasqueira mine has a long history
of production of high-quality wolframite concentrates and is the
dominant producer of high-grade tungsten concentrates outside China.
