- Exploration fieldwork has identified six well mineralized
and outcropping porphyry and related style targets within a 400
metre radius of the Apollo system with assay results for soil and
rock samples as follows:
-
- Gold values up to 8.29 g/t (range of 0.18 g/t to 8.29
g/t);
- Silver values up to 346 g/t (range of 0.2 g/t to 346
g/t); and
- Copper Values of up to 0.14% Copper (range of 31 ppm – 1,410
ppm Cu).
- Surface mapping at all six targets has outlined the same
style of porphyry mineralization as the Apollo system, namely
altered porphyry with vein stockwork, inter-mineral breccia with
oxide followed by sulphides in the matrix and overprinting
late-stage porphyry veins ("CBM Veins").
- Although the amount of rock and soil exposure in the
sampling radius covering each of the six target areas is limited
due to vegetation, historical landslides and volcanic ash cover,
the scale of the areas and tenor of the assay results are similar
to the original outcrop of the Apollo system. The Company estimates
that there is no more than 5% rock exposure anywhere at the
Guayabales project.
- For comparison, the outcrop of the Apollo porphyry system
prior to drilling only measured 10 metres in diameter. Subsequent
drilling has outlined a porphyry system that to date measures 150
metres by 130 metres at surface, which then expands in dimensions
quickly at depth to up to 500 metres wide and remains
open.
- Surface sampling was carried out in oxidized material and if
the oxidation zone shares similar characteristics to the Apollo
system, the copper and silver grades have been reduced by leaching.
Recent drill results from Pad 6 and Pad 7 at Apollo corroborates
this assertion.
- A fourth drill rig is being mobilized to the project and is
expected to initiate testing of the six new targets in late Q2,
2023.
- Six additional holes have been completed at the Apollo
system with assay results expected in the near term. APC-41, APC-42
and APC-45 are shorter holes designed to test the contact zones
between the inter-mineral breccia and porphyry host rock in search
of higher-grade sub zones. APC-44 and APC 46 are longer holes (up
to 425 metres in mineralization) drilled from Pad 6 as part of a
fan pattern to assess the shallow mineralization in this area and
APC-47 is an exploratory hole drilled to the east from Pad 4 to
test for mineralization beginning from below surface.
Ari Sussman, Executive Chairman
commented: "The discovery of these new mineralized porphyry
outcrops around Apollo are both exciting and significant for the
Company. The original discovery outcrop of Apollo only covered a 10
metre radius and subsequent drilling has demonstrated that Apollo
has the morphology of an inverted carrot with limited surface
expression. This fact puts these new targets into perspective and
highlights that the Apollo area is highly prospective for further
exploration. We only found these new outcrops because of various
recently excavated tracks emplaced to service and supply the
drilling pads. I am looking forward to new drill rigs turning at
these targets in the near term."
TORONTO, April 18,
2023 /CNW/ - Collective Mining
Ltd. (TSXV: CNL) (OTCQX: CNLMF) ("Collective"
or the "Company") is pleased to announce exploration
results from six newly generate porphyry and related style targets
located within the Apollo target area at the Guayabales project
located in Caldas, Colombia. The
Apollo porphyry system is a high-grade, bulk tonnage
copper-silver-gold system, which owes its excellent metal endowment
to an older copper-silver and gold porphyry system being
overprinted by younger precious metal rich, carbonate base metal
vein systems (intermediate sulphidation porphyry veins) within a
magmatic, hydrothermal inter-mineral breccia body currently
measuring 395 metres x 385 metres x 915 metres and open for
expansion.
Details (See Table 1 and Figures
1-3)
Exploration fieldwork has identified six target areas with
outcropping porphyry style mineralization which are located within
a 400 metre radius of the Apollo porphyry system. These new targets
were generated by geological mapping, soil sampling and most
importantly the emplacement of new tracks to enable supplies and
equipment to be transported to the current drill pads in the area.
Two key characteristics pertinent to understanding the potential
impact of the targets and their associated metal values in rock and
soil are as follows:
A.
|
Collectively, the
targets consist of all the same mineralization styles observed in
the Apollo system, namely early-stage porphyry style with various
porphyry veinlets, inter-mineral breccia, and late stage CBM veins
which host higher values of gold and silver. The copper values
range between 31 ppm and 1,410 ppm and reflect leaching of copper
and silver due to surface oxidation. The leaching of copper in
oxides at Apollo has been observed in all oxidized material drilled
from Pad 6 and Pad 7. Copper values near surface in these drill
holes display very similar grades to those observed in the six
outcrops outlined in this release. Gold values range from 0.18 g/t
to 8.29 g/t and silver values from 0.2 g/t to 346 g/t with
variation in both cases related to the mineralization styles
encountered.

B.
|
Cognizance must be
taken of the surface area and 3D morphology of the Apollo porphyry
system when assessing these new porphyry outcrops. The original
Apollo discovery outcrop was only 10 metres in diameter and was the
only exposure identified prior to the drilling of discovery hole
APC-1. The discovery outcrop had gold, silver, and copper values in
the ranges of 0.07 to 4.1 g/t gold, 1.9 to 29 g/t silver and 377 to
1,023 ppm copper. After the erection of multiple drill pads,
another two outcrop areas were located at Apollo following the
construction of various tracks which were emplaced to service the
various drill rigs with equipment and supplies. There is only
approximately 5% outcrop exposure at the Guayabales project due to
the dense vegetation and the covering of primary rock surfaces by
historic landslide fill and young volcanic ash. Furthermore,
drilling at the Apollo deposit has demonstrated that the surface
expression is relatively small with a maximum known diameter at
present of 150 metres whereas at depth this expands quickly to a
known diameter of up to 500 metres. The deposit is still open in
all directions.

The following brief descriptions and data are summarized for
each outcrop target:
Target 1:
This target is located 200 metres west of the Apollo outcrop
area. This outcrop has dimensions of 20 metres by 3 metres and
hosts early-stage porphyry mineralization as well as clast
supported crackle breccia with an iron oxide matrix cement of 3% to
5% in volume. Drusy quartz veining is superimposed on the breccia.
Pervasive and strong sericite alteration overprints the rock
exposures. Gold grades range from 1.13 g/t to 0.34 g/t with silver
ranging from 0.2 g/t to 6.6 g/t and copper in the range of 90 ppm
to 224 ppm.
Target 2:
This target is located 300 metres northeast of the Apollo
system, has outcrop dimensions of 120 metres by 60 metres and
contains a couple of historical and shallow artisanal mines.
Geological mapping has identified altered porphyry hosting angular
breccia with quartz diorite clasts. The matrix of the breccia has
total sulphides of up to 5% which is predominantly pyrite with some
chalcopyrite. CBM veinlets overprint the breccia and trend NW and
EW. Alteration is strong and defined by sericite and chlorite. Gold
values range from 8.29 g/t to 1.51 g/t, silver from 10 g/t to 346
g/t and copper from 72 ppm to 362 ppm.
Target 3:
Target 3 is located 300 metres east-northeast of the Apollo
system and has outcrop dimensions of 15 metres by 3 metres. The
outcrop area hosts angular breccia with quartz diorite clasts with
an iron oxide cement (1%-2%) after sulphides. Strong
Sericite-chlorite alteration is observed. The target has
subsequently been expanded to 75 metres by 170 metres by anomalous
gold in soil values. Rock samples range from 0.18 g/t to 0.63 g/t
gold, silver ranges from 2 g/t to 68 g/t and copper from 43 ppm to
277 ppm.
Target 4:
This target is located 250 metres east of the Apollo system with
dimensions measuring 20 metres x 4 metres and host crackle breccia
of diorite composition and altered porphyry rocks. Breccia cement
hosts 2%-3% iron oxide after sulphide while both the porphyry and
breccia units are overprinted by CBM veinlets. Strong sericite
alteration is observed in the outcrop. The target has been expanded
to 150 metres by 100 metres by anomalous gold in soil values. Rock
samples range from 0.90 to 4.31 g/t gold, 1 g/t to 56 g/t silver
and copper ranges from 125 ppm to 323 ppm.
Target 5:
This target area is located 100 metres due east of the Apollo
system and has dimensions measuring 15 metres by 10 metres. Geology
observed includes altered porphyry, angular breccia and late stage
CBM veinlets. The breccia matrix hosts 3%-5% iron oxides after
sulphide with strong sericitic alteration. Anomalous soil sample
results for gold have expanded the target area to 200 metres by 100
metres. Rock samples range from 0.56 g/t to 5.59 g/t gold, 6 g/t to
70 g/t silver and copper ranges from 477 ppm to 833
ppm.
Target 6:
This target area is located 400 metres due southeast of the
Apollo system and outcrops over a 30 metre diameter area. The
outcrop hosts angular, polymictic, clast supported breccia (diorite
and quartz diorite) and altered porphyry with quartz veinlets. The
matrix cement hosts visible sulphides of 3%-5% and consists of
chalcopyrite, sphalerite, galena and pyrite. Rock samples range
from 0.39 g/t to 1.07 g/t gold, 6 g/t to 20 g/t silver and copper
ranges from 32 ppm to 1,410 ppm.
Update on Apollo Drilling
Progress
The Phase II drilling program of 2023 is advancing on schedule
with thirteen holes completed and a further six holes in the lab
awaiting assay results. Since the discovery of the Apollo porphyry
system was announced in June 2022, a
total of 44 drill holes (approximately 18,978 metres) have
been completed and assayed.
Six additional holes have been completed from the three current
drill pads with assay results expected in the near term. APC-44 and
APC-46 are long holes drilled in westerly direction with continuous
visual mineralization of up to 425 metres. APC-41, APC-42 and
APC-45 are shorter holes designed to test the contact zones between
breccia and porphyry in potentially higher-grade areas. APC-47 is
an exploratory hole drilled to the east from Pad 4. Assay results
are expected in the near term.
The Company presently has three diamond drill rigs operating at
the Apollo project and additional assay results are expected in the
near term.
The Apollo target area, as defined to date by surface mapping,
rock sampling and copper and molybdenum soil geochemistry, covers a
1,000 metres X 1,200 metres area, and represents a large and
unusually high-grade Cu-Ag-Au porphyry system. Mineralization
styles include early-stage porphyry veins, inter-mineral breccia
mineralization and multiple zones of porphyry related late stage,
sheeted, carbonate-base metal veins with high gold and silver
grades. The Apollo target area is still expanding as the Company's
geologists have found multiple additional outcrop areas with
porphyry veining, breccia, and late stage, sheeted, carbonate base
metal veins.
