Alhambra Resources: Deep Core Drilling at Uzboy Confirms the Intersection of Several Zones of Higher-Grade Gold Mineralization
2011年11月7日 - 9:00PM
Marketwired Canada
Alhambra Resources Ltd. (TSX VENTURE:ALH) ("Alhambra" or the "Corporation"), an
international gold explorer and producer, announces assay results for seven
diamond drill holes ("DDH") completed southwest of the West Zone of the Uzboy
gold deposit ("Uzboy"). The DDH drilling program has extended the zone of gold
mineralization in West Uzboy to depth and along strike including the
intersection of several zones of higher-grade gold mineralization.
Uzboy is one of three advanced exploration project areas within Alhambra's 9,800
km2 Uzboy Project located in north central Kazakhstan (see location map, Figure
1).
HIGHLIGHTS
-- A down-plunge extension of a higher-grade zone of gold mineralization
has been confirmed,
-- Gold mineralization has been expanded by 225 metres ("m") along the dip
and 60 m along strike,
-- Broad intervals (from 9.0 m to 46.0 m) of gold mineralization were
intersected in all seven diamond drill holes,
-- The deposit is still open on strike to the southwest and at depth.
DRILLING PROGRAM
The Uzboy deep drilling program consisted of seven DDH totaling 3,418.2 m (see
Figure 2). The objective of this drilling program was to delineate additional
relatively shallow sulphide gold mineralization along strike of the zones of
West Uzboy and to delineate additional sulphide resources at deeper depths of
the deposit. Both of these objectives were achieved.
Three of the seven deep holes totaling 1,776.2 m, which ranged in depth from
520.2 m to 700.0 m, were completed to test the steep plunge of the gold
mineralization immediately southwest of the known main zone (Zone #3) of West
Uzboy. Two holes (being 230.0 and 350.0 m in depth) were drilled to check for
the presence of sulphide mineralization above the steep plunge. Two more holes
(530.0 and 520.0 m deep) were drilled to test the down dip extension of another
mineralized zone (Zone #4) within West Uzboy.
Table 1 summarizes the assay results from the seven core holes completed. The
mineralized intercepts were calculated using a 0.2 grams per tonne gold ("g/t
Au") cut-off and a maximum 2 m interval of internal waste. No uppercut was
applied to the assay results.
A down-plunge extension of a higher-grade zone of gold mineralization was
confirmed. Multiple intervals of gold mineralization were intersected in these
three DDHs (P734, C791A and P792) (see cross-sections, Figure 3) over intervals
that ranged in width from 3.00 m to 46.00 m at core depths from 322.70 m down to
694.00 m. The deepest known vertical depth of mineralization from surface
intersected to date within the Uzboy gold deposit occurred in DDH P792 whereby
the vertical depth was extended by 52% to 570 m from 375 m.
DDH P734 intersected 1.53 g/t over 41.90 m, including a higher grade interval of
31.70 g/t over 1.00 m, and 10.23 g/t over 2.20 m. DDH P792 intersected 0.95 g/t
over 46.00 m, including a higher grade interval of 5.43 g/t over 5.00 m and 0.90
g/t over 10.00 m.
Broad intervals of gold mineralization were intersected in all holes drilled.
Six of seven holes intersected three to five intervals of gold mineralization
each, ranging in width from 3.0 m to 46.0 m and at core depths from 166.5 m to
694.0 m. Of great interest is hole C431 which was drilled to test the deeper
part of another zone of West Uzboy (Zone #4). This hole returned a 22.9 m wide
interval of 2.82 g/t improving the parameters of Zone #4 which the Corporation
anticipates may potentially lead to an increase in resources. Above widths
expressed are not true widths.
The main zone of West Uzboy has now been extended along the dip by an additional
225 m and has been traced over a minimum strike length of 60 m between Section
73 and Section 79. It is open on strike to the southwest and open at depth.
Additional diamond drilling is required to further trace the zone of gold
mineralization outlined to date.
All assay results have been forwarded to Alhambra's independent geological
consultant, ACA Howe, for inclusion in the updated National Instrument ("NI")
43-101 resource estimate report for Uzboy that is currently being prepared.
DRILLING AND SAMPLING PROCEDURES
An NQ diamond drilling core barrel was utilized and core recovery was 100%. The
core was split by the independent drilling contractor under the supervision of
the Corporation's geologists with one half used for sampling and another half
left for references. Every meter of core was sampled inside the zones of
hydrothermal alterations and two meter core samples were taken in unaltered host
rocks. The exact borders of the sampling interval were determined according to
the lithological contacts. The average sample weight was 2.5 kilograms.
Sample preparation was completed by Stewart Assay and Environmental Laboratories
located in Kyrgyzstan using the following procedure: samples were crushed to
minus 2 mm, mixed and split into two 200 gram sub-samples. One sub-sample was
pulverized to - 200 mesh and the other sub-sample was retained for reference
purposes. A 30 gram sample of the -200 mesh material was used for fire assay
with atomic absorption finish. Stewart Assay and Environmental Laboratories is
independent of Alhambra and does have an International Standard Organization
("ISO") 17025 accreditation.
QUALITY ASSSURANCE QUALITY CONTROL
The Kyrgyzstan Stewart Assay and Environmental Laboratories, as a part of
Stewart Group, have stringent quality assurance and quality control ("QA/QC")
procedures. Alhambra also follows a rigorous QA/QC program consisting of
inserting standards, blanks and duplicates into the sample stream submitted to
the laboratory for analysis to ensure that the sampling and analysis of all
samples is conducted in accordance with the best possible practices.
