Darwin Resources Corp. ("Darwin" or the "Company") (TSX
VENTURE:DAR)(PINKSHEETS:DARWF)(FRANKFURT:DWU): Darwin is pleased to announce
results from the Company's maiden drill program at the Suriloma epithermal gold
project in the Department of La Libertad, northern Peru.
Key results:
-- Nine diamond holes were drilled at La Puerta and two at Inmaculada for a
total of 1,603 metres over a combined strike length of 1.3 kilometres.
-- Approximately 75% of the 5 kilometre-long epithermal system remains
untested along strike.
-- Better drill intersections at La Puerta include:
-- 13.1 metres @ 1.4 g/t gold from 50.8 metres (down hole depth),
including 2.0 metres @ 5.8 g/t gold and 24.1 g/t silver in SU-003
(Zone B);
-- 7.5 metres @ 2.3 g/t gold from 84.2 metres, including 2.0 metres @
5.0 g/t gold in SU-004 (Zone A);
-- 24.3 metres @ 0.8 g/t gold from 84.2 metres, including 1.2 metres @
6.2 g/t gold and 17.6 g/t silver in SU-008 (Zone B);
-- 14.7 metres @ 0.9 g/t gold from 123.2 metres, including 0.5 metres @
7.0 g/t gold and 0.3 metres @ 8.6 g/t gold in SU-011 (Zone B);
-- 7.8 metres @ 1.5 g/t gold from 57.1 metres in SU-001 (Bosque);
-- The average vertical depth of drill hole intersections at Zone B was 65
metres, and the deepest was 102 metres. Mineralization is open in all
directions.
-- Drilling at La Puerta confirmed the discovery of multiple epithermal
gold-bearing veins and hydrothermal breccias enveloped by wide illite-
smectite-pyrite alteration (i.e. intermediate argillic alteration)
zones. Sulfide mineralization was intersected within 20 metres of
surface in the majority of drill holes.
-- It is interpreted that drilling has intersected the upper, low-
temperature part of an epithermal vein system and that precious metal
grades could significantly improve with depth.
-- Follow-up exploration at Suriloma will include IP electrical geophysics
and ground magnetics to investigate a new range of vein and porphyry
targets including at La Puerta, Inmaculada, Edelmira, and Guadalupe.
These investigations will be followed-up by further diamond drilling.
Dr Graham Carman, President and CEO of Darwin, said: "This maiden drill test at
Suriloma has confirmed the potential of our La Puerta discovery. Epithermal
vein-style gold mineralization was intersected in all nine holes at La Puerta.
Significantly, exploration of Suriloma remains at an early stage, with
geological studies indicating the potential for higher gold grades at depth. La
Puerta has been tested to an average depth of only 65 metres, with more than 75%
of the 5 kilometre mineralized strike at surface yet to be drilled. Furthermore,
recent surface mapping identified potential for a porphyry system at Edelmira, 4
kilometres west and structurally below the epithermal system. Darwin now plans
to undertake IP and ground magnetic geophysical surveys to assist in determining
the best targets for future drilling. A highlight of the drill program was the
excellent cooperation and assistance received by Darwin from the local
communities, and we look forward to continuing our positive working relationship
with all stakeholders."
Drill program outline
In total, nine (9) diamond holes were drilled at the La Puerta area, and two (2)
at the adjacent Inmaculada area. Holes were separated by an average of 100
metres and drilled perpendicular to the west-northwest trend of the structures
to an average down-hole depth of 145 metres on an inclined angle. A total of
1,603 metres were drilled in eleven (11) holes, covering a combined strike
length of 1,300 metres. Figure 1 shows known Suriloma target areas. All
significant drill results are summarized in Table 1.
Interpretation of drill results
Results from the drilling at La Puerta are summarized in a plan of the drilling
program (Figure 2) and also in a longitudinal section (Figure 3). Significant
gold mineralization is associated with multiphase quartz veins accompanied by
pyrite and arsenopyrite. The widest structures (Zone A and Zone B) have up to 50
metre-wide clay alteration haloes and show variable degrees of hydrothermal
brecciation.
It is well understood that epithermal vein systems commonly have a strong
vertical zonation of gold and/or silver with 'bonanza' grades typically
associated with quartz and illite (i.e. 'phyllic' alteration with or without
adularia). Testing by Darwin of 167 drill samples from La Puerta and Inmaculada
using a Terraspec X-ray analyser indicates that clay minerals in the mineralized
zones are mostly illite-smectite (i.e. 'intermediate-argillic' alteration).
Based on these results it is interpreted that drilling has intersected the
upper, cooler part of an epithermal vein system. Therefore, it is interpreted
that precious metal grades could significantly improve with depth.
Disseminated sulfide associated with intermediate-argillic alteration was
generally intersected at around 20 metres in all drill holes, with no
significant oxide gold intersections made during the drill program. Oxide gold
mineralization may be better developed on other veins or further along strike.
Darwin believes that these initial drilling results from La Puerta are
promising, and warrant further follow up. Vein targets untested by drilling
include Edelmira, Santa Felicita, and Guadalupe, while recent surface mapping
has identified potential for a porphyry system 4km west and structurally below
the epithermal system at La Puerta. Chimu Formation quartzite is the host of
gold mineralization at the Lagunas Norte mine 30km to the southeast (5.8 million
ounces proven and probable gold reserves: Barrick website) and also at La Arena
50km to the southeast (5.5 million ounces measured and indicated gold resources:
Rio Alto website). Chimu Formation lies beneath the andesite at La Puerta at
relatively shallow depth. Darwin previously sampled up to 10 g/t gold from veins
cutting quartzite outcrops at Mina Leje 5km to the west of La Puerta (Figure 1).
Upcoming work
An IP electrical geophysical survey and ground magnetic survey are planned for
Q3 2013 to assist in identifying a new range of epithermal vein and porphyry
drill targets along strike of recent drilling and at depth.
The qualified person, Dr Graham Carman, Darwin's President and CEO, and a Fellow
of the Australasian Institute of Mining and Metallurgy, has reviewed and
verified the technical contents of this release.
Technical Background
True thickness is estimated to be 65-70% of the average drilled width of the
mineralized structures which are sub-vertical to steep north dipping. The
drilling was undertaken by RAM Peru SAC of Lima Peru who provided HQ diameter
core. Drill recoveries were excellent and average close to 100% in fresh rock.
After photographing and logging, core intervals averaging 1.5 metres in length
(about 3.5 kg per sample) were cut in half at Darwin's core cutting shed in
Otuzco Peru. The samples were then transported by courier service to the
Certimin laboratory in Lima. The remaining half core is retained on site for
verification and reference purposes. At Certimin the samples were weighed,
dried, crushed to -2mm, and split with a 500g sample pulverized for chemical
analysis. Samples were analyzed by Certimin for gold by 50g fire assay with AAS
finish (method G0107). Thirty five trace and major elements were analyzed by
ICP-AES at Certimin using aquaregia digestion (method G0146). The QA/QC program
of Darwin consists of the systematic insertion of two certified standards of
known gold content, two blanks, and two duplicate samples (each of 1/4 core)
into each batch of 60 samples. Certimin also inserts its own blanks and
standards into the analytical process also.
