- Two reconnaissance holes were drilled eastwards from Pad 6
at the Apollo system to test the potential for high grade
mineralization at the eastern contact zone where the inter-mineral
breccia and the host porphyry vein stockwork meet. Based on prior
observations, the concept to be proved was that the contact zone
forms a trap for the accumulation of excess metal driven by the
location where the late-stage carbonate base metal veins enter the
system. The scout hole, APC-41, was drilled obliquely to the
contact and was not optimally situated to fully test the zone.
Based on the logging of that hole, APC-42 was then appropriately
drilled orthogonal to the contact zone.
- APC-42, which expanded the overall dimensions of the Apollo
system modestly to the southwest intersected high-grade
gold-silver-copper mineralization from surface over a broad
interval with the highest accumulation (grams X metres) of oxide
material encountered to date as follows:
-
- 104.8 metres @ 5.56 g/t gold equivalent (consisting of 4.21
g/t gold, 68 g/t silver and 0.3% copper) including:
-
- 44.6 metres @ 6.99 g/t gold equivalent from surface in
oxides; and
- 20.0 metres @ 6.59 g/t gold equivalent from 84.80 metres
downhole.
- APC-41, which was drilled at a suboptimal angle, also
intercepted high-grade mineralization from surface with a robust
oxide zone as follows:
-
- 82.1 metres @ 3.09 g/t gold equivalent (consisting of 2.81
g/t gold, 13 g/t silver and 0.1% copper) including:
-
- 28.1 metres @ 3.67 g/t gold equivalent from surface in
oxides.
- Six additional holes have been completed at the Apollo
system with assay results expected in the near term. All six holes
intersected cumulative mineralization over varying yet significant
downhole drill lengths. Three drill rigs are operating on site with
a fourth rig expected to begin operating prior the end of Q2,
2023.
Ari Sussman, Executive Chairman
commented: "This new step-out drilling into the eastern area of the
Apollo system has outlined a new and important high-grade zone
where extensive quartz stockwork veining has resulted in an
abundance of high-grade metal being trapped at the interface
between breccia and porphyry. A drill hole from Pad 10, located
northeast from Pad 6, is underway to test this new high-grade zone
along the contact to the northeast. The surprises at Apollo
continue to be positive and I am confident that not only will the
Apollo porphyry system continue to grow with further exploratory
drilling but that we will make new discoveries in the near term by
remaining aggressive with our drilling."
TORONTO, April 25,
2023 /CNW/ - Collective Mining
Ltd. (TSXV: CNL) (OTCQX: CNLMF) ("Collective"
or the "Company") is pleased to announce assay results
from a further two drill holes completed within the Apollo porphyry
system ("Apollo") at the Guayabales project located in Caldas,
Colombia. Apollo 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
1-4)
The Phase II drilling program of 2023 is advancing on schedule
with thirteen holes completed and results announced. A further six
holes have been drilled and await assay results from the lab. The
objectives of the 2023 program is to define the high-grade
mineralization and dimensions of the Apollo porphyry system near
surface, expand the size of the system through step-out and
directional drilling and drill test multiple new targets generated
through grassroot exploration. Since the announcement of the
discovery hole at Apollo in June
2022, a total of 44 drill holes (approximately 18,400
metres) have been completed and assayed.
This press release announces results from two exploratory holes
drilled eastwards from Pad 6 and designed to test the contact zone
between the porphyry and inter-mineral breccia. The first hole,
APC-41, was drilled to the northeast at a shallow angle and was
suboptimal in design as it was drilled oblique to the contact zone.
Based on the understanding gained from the first hole, APC-42 was
drilled steeply due east and intercepted the contact zone at an
orthogonal angle. Assay results and geological observations for
both holes are summarized below:
APC-42 was drilled steeply to the east from
surface at Pad 6 to a maximum downhole depth of 126.3 metres. The
mineralized interval includes 44.55 metres of combined saprolite
and saprock with iron oxides formed from the oxidation of the
sulphides hosted within the matrix of the breccia and within veins.
Below the oxidized zone, the intercept passes into fresh rock with
a sulphide composition of 0.5% chalcopyrite, 1.5% pyrite and
pyrrhotite (up to 0.5%). One of the characteristic features of this
intercept is the fact that it passes through a contact zone between
breccia and porphyry. This zone contains both mineralized breccia
and a stockwork of sulphide bearing quartz and carbonate veins
within the adjacent porphyry material, all of which are associated
with intense sericite alteration. Finally, the footwall zone of the
porphyry is well altered and hosts mineralization associated with
disseminated pyrite and quartz-pyrite veins with assay results as
follows:
- 104.8 metres @ 5.56 g/t gold equivalent (consisting of 4.21
g/t gold, 68 g/t silver and 0.3% copper) including:
-
- 44.6 metres @ 6.99 g/t gold equivalent from surface in
oxides; and
- 20.0 metres @ 6.59 g/t gold equivalent from 84.80 metres
downhole in a porphyry stockwork.
This intercept is followed by 19.35 metres @ 0.33 g/t gold
equivalent from 106.95 metres downhole and is hosted within quartz
diorite porphyry.
APC-41 was drilled to the northeast from Pad 6 to a maximum
downhole depth of 162.4 metres and was designed to test the contact
zone between breccia and porphyry. The mineralized interval starts
at 1.65 metres depth below the overburden and intersects 28.05
metres of combined saprolite and saprock with iron oxides formed
from the oxidation of the sulphides hosted within the matrix of the
breccia and within veins. Below the oxide zone, the intercept
passes into fresh rock consisting of quartz diorite breccia with a
matrix of chalcopyrite (0.2%), pyrite (up to 2%) and 0.1%
pyrrhotite before exiting the breccia and entering into mineralized
quartz diorite porphyry. As in APC-42, the contact zone is
characterized by a stockwork of sulphide bearing quartz and
carbonate, porphyry veins associated with intense sericite
alteration. The sericite is overprinting earlier potassium
alteration (biotite). Finally, the footwall porphyry is altered and
hosts mineralization associated with disseminated pyrite and
quartz-pyrite veins with assay results as follows:
- 82.1 metres @ 3.09 g/t gold equivalent (consisting of 2.81
g/t gold, 13 g/t silver and 0.1% copper) including:
-
- 28.1 metres @ 3.67 g/t gold equivalent from surface in
oxides.
This intercept is followed by a lower grade intercept of 57
metres @ 0.34 g/t gold equivalent from 83.7 metres downhole and is
hosted within quartz diorite porphyry.
Six additional holes have been completed at the Apollo system
with assay results expected in the near term. All holes intersected
bulk tonnage mineralization over core length of up to more than 500
metres. APC-45 and APC-48 were shorter holes drilled from Pad
7, designed to test the contact zone between the inter-mineral
breccia and porphyry host rock in the southern portion of the
deposit. APC-44 and APC-46 were longer holes drilled from Pad 6 as
part of the fan pattern of drilling to assess the shallow
mineralization in the central area of the system. APC-49 was a
deeper hole drilled to the northwest from Pad 6 and APC-47 was
drilled eastwards from Pad 4.
The Company presently has three diamond drill rigs operating at
the Apollo project with a fourth rig expected to begin operating
prior to the end of Q2, 2023. 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. Mineralizations
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.
