Continues to Confirm High-Grade Copper
and Gold Mineralization at
Alacran
Cordoba Minerals Corp.
(TSX-V:CDB)(OTCQX:CDBMF)
(
“Cordoba” or the
“Company”) is
pleased to announce assay results from the remaining three drill
holes completed as part of the 2017 resource expansion diamond
drilling program at the Alacran Deposit, located within the
100%-owned San Matias copper-gold project in Colombia. These
results follow Cordoba’s news release dated December 5, 2017.
The 2017 drilling program at the Alacran Deposit
has been effective at improving the continuity of mineralization
and testing resource expansion potential in areas located to the
north, west and south of the currently defined resource. These new
mineralized zones will be added into the updated Alacran resource
estimate expected during the first quarter of 2018.
Highlights (refer to Table 1
for full results)
- ACD078:
- 0.78% copper and 0.17 g/t gold over 29.5 metres
(0.91% copper equivalent
[“CuEq”]; from 32.0 metres), including:
- 1.51% copper and 0.38 g/t gold over 10.0 metres (1.79% CuEq;
from 40.0 metres).
- ACD079:
- 1.05% copper and 0.29 g/t gold over 46.8 metres (1.28%
CuEq; from 88.4 metres), including:
- 1.88% copper and 0.47 g/t gold over 20.5 metres (2.24% CuEq;
from 109.5 metres).
- ACD081:
- 0.78% copper and 0.18 g/t gold over 64.4 metres (0.92%
CuEq; from 33.6 metres), including:
- 1.61% copper and 0.41 g/t gold over 15.1 metres (1.92% CuEq;
from 52.9 metres).
“The latest results provide another high point
at the end of a very positive 2017 drill program at Alacran,”
commented Mario Stifano, President and CEO of Cordoba Minerals.
“This successful resource expansion program demonstrated the
positive return on exploration investment we have come to expect
from this project. Following our 2017 program, our geologists have
a greater understanding of the mineralized systems at Alacran, and
we look forward to providing the market with an updated resource
estimate as well as commencing additional regional exploration
during 2018.”
Discussion
On Section 855540mN (Figure
1),
- ACD079 has now successfully infilled the 120
metre pre-existing gap within the well-mineralized “footwall manto”
that was intersected by drill holes ACD032 and ACD035 (previously
released in January 2017), now with a new significant intercept
outlined in Table 1.
- 1.05% copper and 0.29 g/t gold over 46.8 metres (1.28%
CuEq; from 88.4 metres) as disseminated chalcopyrite
hosted in massive mudstones-siltstones with albite and sericite
alteration in the lower half of Unit 2 (below a fossiliferous
limestone marker bed) between the footwall of an altered diorite
sill and the top of Unit 3 (same stratigraphic position as seen in
holes ACD032 and ACD035); the upper section of the mineralized
manto was truncated by the above-mentioned diorite sill that is
interpreted to be late-mineral in timing as it only contains low
grades (0.1-0.2% copper) as weak pyrite-chalcopyrite disseminated
in albite-chlorite alteration, and includes:
- 1.88% copper and 0.47 g/t gold over 20.5 metres (2.24%
CuEq; from 109.5 metres).
On Section 855140mN (Figure
2),
- As previously discussed in Cordoba’s December 5, 2017 news
release, ACD078 was drilled as an infill hole to
prove the continuity of mineralization between the intercepts in
ASA011 and ACD038 (previously released in October 2015 and May 2017
respectively) as shown in Figure 2. Completed assay results
recently returned the following significant intercepts, also shown
in Table 1.
- 0.78% copper and 0.17 g/t gold over 29.5 metres (0.91%
CuEq; from 32.0 metres), as chalcopyrite mineralization
hosted essentially in the banded calcareous mudstones above the
fossiliferous limestone marker bed (as in ASA011 and ASA036;
previously released in October 2015), including:
- 1.51% copper and 0.38 g/t gold over 10.0 metres (1.79%
CuEq; from 40.0 metres),
- 0.37% copper and 0.35 g/t gold over 11.4 metres (0.63% CuEq;
from 84.5 metres) in the fossiliferous limestone marker bed,
- 0.47% copper and 0.03 g/t gold over 11.6 metres (0.49% CuEq;
from 271.6 metres) in the fine mafic tuffs in Unit 3 (as observed
in ACD038).
On Section 854740mN (Figure
3),
- As previously discussed in Cordoba’s December 5, 2017 news
release, ACD081 was drilled as a step back hole to
extend 60 metres down-dip the high-grade mineralization intersected
by ACD066 (0.70% copper and 0.19 g/t gold over 48.0 metres;
previously released in July 2017) and also has intersected the
down-dip continuation of the same magnetite-chalcopyrite manto
hosted in the laminated calcareous mudstone sequence at the hanging
wall of the fossiliferous limestone marker bed (upper half of Unit
2) with a significant intercept of:
- 0.78% copper and 0.18 g/t gold over 64.4 metres (0.92%
CuEq; from 33.6 metres), including
- 1.61% copper and 0.41 g/t gold over 15.1 metres (1.92%
CuEq; from 52.9 metres),
- 0.97% copper and 0.20 g/t gold over 6.1 metres (1.12% CuEq;
from 73.5 metres).
Alacran Copper-Gold Project
The Alacran copper-gold system is located within
the San Matias copper-gold project in the Department of Cordoba,
Colombia, 200 kilometres north of Medellin. San Matias comprises of
a 20,000 hectare land-package and contains several known areas of
porphyry copper-gold and iron oxide copper gold, and/or carbonate
replacement deposit mineralization and gold veins.
The Alacran copper-gold system is located on a
topographic high in gently rolling countryside, optimal for
potential open-pit mining. Site access and infrastructure are
considered to be favourable.
The current Inferred Mineral Resources at
Alacran are 53.5 million tonnes grading 0.70% copper and
0.37 g/t gold. Alacran is approximately two kilometres
southwest of the Company’s Montiel porphyry copper-gold discovery,
where drilling intersected 1.0% copper and 0.65 g/t gold
over 101.1 metres (previously reported in DDH-004), and
two kilometres northwest of the Costa Azul porphyry copper-gold
discovery, where drilling intersected 0.62% copper and 0.51
g/t gold over 86.6 metres (previously reported in
CADDH003).
The copper-gold mineralization at Alacran is
associated with stratabound replacement of a faulted calcareous
marine volcano-sedimentary sequence. The deposit comprises
moderately- to steeply-dipping stratigraphy that is mineralized as
a series of sub-parallel replacement-style zones and associated
disseminations. The mineralization is composed of multiple
overprinting hydrothermal events, and the main mineralizing phase
is comprised of chalcopyrite-pyrrhotite-pyrite that appears to
overprint an early magnetite metasomatic event.
Technical Information
The technical information in this release has
been reviewed and verified by Dale A. Sketchley, a Qualified Person
for the purpose of National Instrument 43-101. Mr. Sketchley is a
consultant to Cordoba Minerals and is considered independent under
National Instrument 43-101. Mr. Sketchley is a geologist with
over 40 years in the mineral exploration, mining, and consulting
industry. He is a Member of the Association of Professional
Engineers and Geoscientists of British Columbia (APEGBC) and the
Canadian Institute of Mining and Metallurgy (CIMM).
Copper-equivalent values have been calculated
using a US$1,300 per ounce gold price and US$2.50 per pound copper
price.
Cordoba utilizes a comprehensive
industry-standard QA/QC program. HQ and NQ diamond drill core is
sawn lengthwise in two halves, and one half is sampled and shipped
to a sample preparation laboratory. The other half of the core is
stored in a secure facility for future assay verification. All
samples are prepared at ALS Minerals Laboratory in Medellin,
Colombia, and assayed at ALS Minerals Laboratory in Lima, Peru. ALS
Minerals operates in accordance with ISO/IEC 17025. Gold is
determined by 50 g fire assay with an AAS finish. An initial
multi-element suite comprising copper, molybdenum, silver and
additional elements is analyzed by four-acid digest with an ICP-ES
or ICP-MS finish. All samples with copper values over 2000 ppm are
re-assayed by a method for higher grades, which also uses a
four-acid digest with an ICP-ES finish. Certified reference
materials, blanks, and duplicates are inserted into the sample
stream to monitor laboratory performance.
The Alacran initial Inferred Mineral Resource
estimate was completed by Mining Associates Limited and reported by
the Company on January 5, 2017, and is in accordance with National
Instrument 43-101 and the 2014 Canadian Institute of Mining (CIM)
definition standards. Inferred Mineral Resources are considered to
be too speculative geologically to have the economic considerations
applied to them to be categorized as Mineral Reserves. Mineral
Resources that are not Mineral Reserves do not have demonstrated
economic viability.

rightmost column.
- For intercept calculations: sample assays of copper, gold and
copper equivalent are all capped to 10% copper, 10 g/t gold, and
10% CuEq.
