News Release: January 27th, 2005
Update of Mexican Exploration
Activities
San Carlos Cu-Au-Ag Project,
Mexico
The San Carlos Project is located in northeast Mexico and has
been optioned to Hawkeye Gold and Diamond Inc. (Hawkeye) on terms
whereby Hawkeye can earn a total of 60% of the San Carlos project
by issuing a total of 800,000 shares to Almaden and incurring
exploration expenditures of US$4 Million over seven years. Hawkeye
is committed to spending US$350,000 in the first year.
Hawkeye has informed Almaden
that it has carried out a work program designed to evaluate the
potential for Carbonate Replacement Deposit (CRD) style and copper-gold
skarn mineralization around the 9 km periphery of a Tertiary
intrusion emplaced into a thick section of Cretaceous carbonates
during November through mid December 2004.
CRD's account for a significant
portion of mineral wealth within the Republic of Mexico including
deposits whose production and reserves reportedly total in excess
of 400 Mt of silver-lead-zinc ore with appreciable copper and
gold credits. The deposits are clustered along the Mexican fold
and thrust belt within a 1600 by 450 km wide corridor extending
through the east and central portions of the country. The two
closest major mining districts to the San Carlos property are
the Conception del Oro and the Charcas Districts situated roughly
350 km west and southwest respectively. These districts have
reported production exceeding 75 Mt. The average production grade
at Conception del Oro is reported to be 12.8% zinc, 5.8% lead
and 275 g/t silver in 40 plus Mt.
The San Carlos project area
occupies a localized region of relatively rugged topography;
however outcrop exposure is relatively sparse due to extensive
jungle and talus cover. Hawkeye informed Almaden that the first
phase exploration program consisted of approximately 31 km of
line cutting over four square kilometers around the eastern and
northern parts of the property. Detailed mapping, prospecting
and soil geochemical surveys were almost completely restricted
to the grid due to the extensive peripheral cover. A twenty-one
kilometer ground geophysical Induced Polarization (IP) survey
was also completed. An excerpt of Hawkeye's news release of January
25, 2005 follows:
Three styles of mineralization
were encountered during the Phase I program and they comprise
Cu-W-Au skarn, Ag-Au quartz veining and quartz healed fracture
filling, Ag-Au-Zn sulphide veining and Ag-Au-Pb-Zn-Cu siderite/jasperoid
veining. The order in which the styles of mineralization are
listed is somewhat reflective of their proximity to the main
intrusive body; skarns forming proximally and siderite/jasperoid
veins distally to the intrusion.
Highlights for rock samples
collected are listed in Tables 1 to 4.
Table 1 Cu-W-Au Skarn:
Cu-W-Au skarn mineralization
was documented in both the eastern and northern parts of the
grid. At the eastern locale, it occurs as tan weathering, finely
banded, limonitic brown garnet-magnetite skarn. A 0.5 m chip
sample taken across the recessive skarn exposure yielded 2.22
g/t Au, 9.9 g/t Ag, 0.20% Cu and 60 ppm W. Abundant banded, hematitic,
manganiferous jasperoid containing moderate amounts of limonite
and minor magnetite was discovered in the northern part of the
property emanating from a drainage near the intrusive/carbonate
contact. A series of samples collected yielded elevated values
for copper (to 0.18%), tungsten (to 0.10%) and gold (to 0.20
g/t).
Table 2 Au-Ag Quartz Veins:
Silica flooding occurs at
several locales within the main monzonite stock in association
with fracture zones developed in the vicinity of the Cu-Au skarn
roof pendants. A sample of this material collected from the San
Narciso mine site yielded 2.9 g/t Ag, 0.26% Cu and 0.10 g/t Au.
In the eastern portion of
the property, gold and silver values of 8.33 g/t and 180 g/t
respectively, were obtained from finely laminated manganiferous
limonite containing moderate amounts of dark grey quartz lenses
and white quartz fragments. This material is believed to be associated
with silica healed fracture zones within the carbonates. Similarly,
a 3 cm wide piece of white quartz vein talus containing minor
dark brown oxide pits and trace amounts of disseminated pyrite
yielded 4.27 g/t Au and 19.9 g/t Ag. Both samples were collected
from the central portion of a gold anomaly identified by previous
operators in the vicinity of a soil sample site which reportedly
yielded 1.93 g/t Au.
Table 3 Au-Ag-Zn Sulphide Vein
/ Silicification Zones:
A series of old workings also
discovered within the eastern portion of the grid consists of
three square pits excavated along a 330° fracture zone which
is associated with highly silicified grey porous limestone. Insitu
smithsonite samples collected from a 20 cm wide vein in one of
the pits returned 37.5% Zn with anomalous accessory lead, silver
and copper. A 1.2 m chip sample taken across a silicified hanging
wall exposure from one of the pits yielded 3.44 g/t Au, 4.7 g/t
Ag and 1.44% Zn. The zone is exposed intermittently for roughly
25 m before it is obscured by jungle and talus.
A 1 cm massive pyrite veinlet
cutting massive limestone at a similar orientation was documented
400 m north of the workings. Chips of this material collected
returned 1.46 g/t Au, 41.2 g/t Ag and 1.28% Zn.
Table 4 Au-Ag-Pb-Zn Siderite
/ Jasperoid Veins:
Siderite/jasperoid veins and
vein talus were documented within the eastern portion of the
property up to 1.5 km from the main monzonite stock. They are
steeply dipping, consist of strongly manganiferous red-brown
siderite and jasperoid with moderate concentrations of limonite
and trace galena. They are generally between 20 cm and 30 cm
wide. Samples collected from four sites returned up to 3.73 g/t
Au, 37.2 g/t Ag, 1.52% Pb and 5.63% Zn.
The Cu-W-Au mineralization
is constrained mostly to the northern portion of the property
while the mineralization described in tables 2 to 4 was collected
from a 1.5 by 1.5 km area in the eastern part of the claim block.
Soil geochemical sampling
was conducted within a four square km area around the north and
eastern periphery of the San Jose monzonite intrusion. The elements
gold, silver, copper, lead, zinc, manganese and arsenic were
the primary considerations for defining areas of geochemical
interest. Table 5 lists these elements and anomalous thresholds.
Table 5 Geochemical Thresholds:
The most widely anomalous
element of significance for CRD style mineralization is zinc,
with values greater than 100 ppm forming an intermittent linear
north trending band 3 km long and 1.3 km wide. Clusters of moderately
anomalous response outline northwest trends up to 1 km long and
100 m wide. One of these anomalies is believed to coincide with
the southeastern extension of the smithsonite silicification
zone. Manganese and arsenic response are also largely coincident
with zinc while silver and lead values are weakly elevated but
do form small clusters that are coincident within the outer periphery
of the grid.
Gold geochemical response
is strongest in the east central portion of the grid, in an area
sampled by previous operators. The anomaly is situated approximately
200 m east of the main monzonite intrusion. Gold values greater
than 150 ppb reportedly outlined a continuous northerly trend
some 900 m long by up to 450 m wide with peak values up to 2.09
g/t. A 500 m by 400 m section of the grid was resampled in 2004
to test the reproducibility of these numbers. Within the test
block, sampling outlined a linear north trending anomaly roughly
400 m by 300 m in size with peak values up to 2.57 g/t Au and
strong supporting values over 500 ppb Au. Silver response is
also elevated and strongly coincident in this part of the grid
with peak values of 23.6 g/t. The highest gold-silver bearing
rock sample (8.33 g/t Au and 180 g/t Ag) was collected approximately
200 m south along strike of the anomaly.
A total of 21 km of Induced
Polarization survey was completed using a pole-dipole technique
in a six to eight level array at 50 m slope chained intervals.
The data is currently undergoing inversion modeling and interpretation
which should be completed by the end of January. The IP crew
has been mobilized back to the property to complete the survey
over the existing grid and prepare infill lines in the vicinity
of anomalies identified during the initial phase of ground geophysics.
HAWKEYE is very encouraged
with the results received to date from its San Carlos project.
Historical exploration and production of the copper-gold skarn
mineralization within the San Jose monzonite was successful primarily
due to preservation of the surface exposures. Conversely, the
CRD and peripheral copper-gold skarn mineralization, currently
being explored by HAWKEYE, is most likely limited to non-outcropping.
Mineralization discovered to date is considered to represent
alteration commonly observed in the distal and upper portions
of CRD systems. The lead-zinc-silver metal signature is also
typical and further enhanced by strong gold support.
Samples described above were
collected under the supervision of Mr. Bill Wengzynowski P.ENG.,
and analyzed at ALS Chemex Labs of North Vancouver. Mr. Wengzynowski
is also the Company's project Geological Engineer and qualified
person (QP) in accordance with Canadian Securities Association
(CSA) National Instrument (NI) 43-101.
Almaden's management view
these results as very encouraging and representative of a large
magmatic hydrothermal system with potential to host several mineral
deposit types including replacement Ag-Pb-Zn massive sulphides
deposits and Cu-Au skarn deposits. [San Carlos +]
Galeana Au-Ag Project,
Mexico
Almaden has been informed by its joint venture partner Grid Capital
Corp (Grid) that Grid has completed a diamond drill program on
the Galeana gold-silver property in Chihuahua State, Mexico.
Under terms of the joint venture with Almaden, Grid can earn
a 60% interest in the Galeana property by spending US$2,000,000
and issuing 400,000 shares to Almaden.
Grid has informed Almaden
that the drill program tested one of the vein systems identified
on the property, the Miguel Ahumada zone. The Galeana property
hosts three major classic epithermal banded quartz-adularia vein
systems, the San Miguel-Ahumada-Estrella de Oro, the Faldo Norte
and the San Geronimo. All have had limited historic production
prior to the Mexican revolution when all mining activity ceased.
Mapping, sampling and alteration mineralogic and petrographic
analyses of the veins in the Galeana area has resulted in the
interpretation that the exposed veins represent a high level
within the original hydrothermal system. This interpretation
coupled with the identification of high gold grades in fragments
found in breccia bodies identified as part of the Miguel Ahumada
vein system, suggest that the potential to identify high grade
gold and silver ore shoots in the veins may increase with depth.
An excerpt from Grid's December 26th news release follows:
The drill program, consisting
of 3 diamond drill holes totaling 560 meters, tested the San
Miguel Ahumada zone, one of three major vein structures on the
property. All three holes intersected zones of brecciation with
local zones of silicification and minor quartz veining. The highest
value was intersected in hole GAD04-05, where a 0.73 meter core
interval from 129.12 meters to 129.85 meters assayed 5.01 g/t
gold.
Almaden is waiting for a detailed
geological report from Grid which would better enable an assessment
of the results.
Grid informed Almaden that
it's drill program on the Galeana property was carried under
the direction of Mr. Juan Caelles, Ph.D., P. Geo., a qualified
person within the meaning of National Instrument 43-101 and that
samples were sent to ALS Chemex Labs in North Vancouver for analysis. [Galeana
