- Drill hole APC-45, which is the first hole into the Contact
Zone in the southernmost part of the Apollo porphyry system from
Pad 7, intersected an abundance of sheeted CBM veins overprinting
earlier porphyry mineralization. Remarkably continuous high-grade
gold-silver-copper was intersected over the entire core length with
results as follow:
-
- 162.20 metres @ 3.90 g/t gold equivalent commencing from
surface (consisting of 2.59 g/t gold, 29 g/t silver and 0.56%
copper);
- The linear strike length for the Contact Zone between APC-45
and previously announced discovery holes APC-41 and APC-42 now
measures approximately 150 metres and remains open to the northeast
along strike for further expansion; and
- Three additional holes designed to test various parts of the
Contact Zone (APC-53, APC-58 and APC-59) have been completed. Assay
results for APC-53, a northeastern directed step-out hole are
anticipated in June while results for APC-58 and APC-59 are
expected in July.
- Hole APC-48 was drilled to the southwest from Pad 7 and
successfully expanded the overall footprint of the shallow
mineralization to the southwest. Interestingly, the hole exited the
brecciated portion of the Apollo porphyry system and continued to
the end of the interval in a mineralized precursor porphyry unit
with overall results as follows:
-
- 114.40 metres @ 2.38 g/t gold equivalent commencing from
surface (consisting of 1.71 g/t gold, 15 g/t silver and 0.29%
copper) within 236.70 metres @ 1.35 g/t gold equivalent.
- As a result of APC-48, the maximum known strike length of
the system has increased to 435 metres (previously 385 metres) with
the overall maximum known dimensions now measuring 435 metres
strike x 385 metres width x 915 metres vertical. The system remains
open for expansion in most directions.
- Hole APC-47 was drilled in an easterly direction from
Pad 4 in order to cut across the system in an area of the block
model with limited information. A long and continuous interval of
high-grade gold-silver and copper mineralization was intersected
with results as follows:
-
- 307.60 metres @ 2.53 g/t gold equivalent from 226.80 metres
downhole (consisting of 1.40 g/t gold, 53 g/t silver and 0.25%
copper).
- Two drill holes, APC-49 and APC-55 were designed to explore
the depth potential of the Apollo system from Pad 6 to the
northeast and northwest respectively. Detailed visual logging of
both holes indicates that long and continuous zones of
mineralization were encountered from surface to downhole depths of
840 metres and 790 metres respectively. APC-49 was terminated while
still in mineralization due to a drilling related issue while
APC-55 will expand the over dimensions of the Apollo system to the
northeast if it is mineralized to the end of the interval.
Assay results for these holes are expected in late June 2023.
- Eleven additional holes have been completed at the Apollo
system with assay results expected in the near term. All eleven
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 to the
end of Q2, 2023. Once onsite, the fourth rig will focus on testing
the six new exploration targets directly surrounding the Apollo
system as well as regional targets within the three-kilometre
porphyry corridor (see press release dated April 18, 2023, for further details).
Ari Sussman,
Executive Chairman commented: "The Contact Zone at the Apollo
system continues to intercept impressive high-grade mineralization
and importantly can now be traced over a meaningful strike length.
June 2023 is shaping up to be an
exciting and important month for the Company with assay results
expected for Contact Zone drill hole APC-53 and deep holes APC-49
and APC-55. Additionally, our aggressive exploration focus will
expand with a fourth rig scheduled to arrive on site in late June.
This rig will be designated to systematically test exploration
targets surrounding the Apollo porphyry system and the greater
Guayabales project."
TORONTO,
May 30,
2023 /CNW/ - Collective Mining Ltd. (TSXV:
CNL) (OTCQX: CNLMF) ("Collective" or the
"Company") is pleased to announce assay results from a
further three drill holes as well as visual observations for two
long drill holes which tested the depth potential of 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 and diorite porphyry bodies currently measuring 435 metres
x 395 metres x 915 metres and open for expansion.
Details (See Table 1 and Figures
1-3)
The 2023 Phase II drilling program is advancing
on schedule with eighteen holes completed and results announced. A
further eleven holes have been drilled and await assay results from
the lab. The objectives of the 2023 program are to define
high-grade mineralization, the 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 grassroots exploration. Since the announcement of
the discovery hole at Apollo in June
2022, a total of 49 drill holes (approximately 21,487
metres) have been completed and assayed.
This press release outlines results from three
holes. APC-45 and APC-48 were drilled in southerly and south
westerly directions from Pad 7 while APC-47 was drilled to the east
from Pad 4. APC-45 was designed to test the Contact Zone (where the
intermineral breccia ends at a contact with quartz diorite
porphyry) at shallow levels in the southern portion of the deposit.
APC-48 was designed to test the mineralization potential in the
porphyry host rock to the south of the Apollo system while APC-47
was designed to test a large void in the block model for the Apollo
system. Additionally, visual observations are provided for two long
holes, APC-49 and APC-55, which were drilled to the northwest and
northeast respectively from Pad 6. Results for all holes are
summarized below:
APC-45 was drilled steeply (-85°) in
a southerly direction from Pad 7 to a maximum downhole depth of
238.4 metres and was designed to test the Contact Zone between
breccia and porphyry host units as well as the high-grade copper
mineralization previously encountered at shallow levels in this
area. The mineralized interval of oxidation (saprolite) commenced
from surface to 17.05 metres and was then followed by a transition
zone to 39.55 metres down hole. The transition zone hosts iron
oxides formed from the oxidation of the original sulphides hosted
within the matrix of the breccia and within veins. Below the zone
of oxidation, the intercept passed into fresh rock consisting of
mineralised quartz diorite breccia with a sulphide matrix
composition of 1.5% chalcopyrite, pyrite up to 5% and
pyrrhotite (up to 3.0%). Continuous mineralization was encountered
until 162.20 metres (160 metres vertical). A high-grade zone of
carbonate base metal veins ("CBM veins") was intercepted from just
below the transition zone until 54 metres depth. Notably,
exceptional and continuous mineralization was intercepted along the
interval with grades increasing as the hole approached the physical
contact between breccia and quartz diorite porphyry The Contact
Zone contains excellent gold, silver and copper grades associated
with the sulphide matrix and overprinting quartz-carbonate and
sulphide veining with complete assay results for the hole as
follows:
- 162.20 metres @ 3.90 g/t gold equivalent commencing from
surface (consisting of 2.59 g/t gold, 29 g/t silver and 0.56%
copper) and including:
-
- 17.05 metres @ 3.50 g/t gold equivalent in oxide and
transition zones;
- 36.95 metres @ 5.08 g/t gold equivalent from 17.05 metres
downhole in a sheeted CBM zone; and
- 27.10 metres @ 6.70 g/t gold equivalent from 127.90 metres
downhole at the breccia to porphyry contact.
APC-47 was drilled in an easterly
direction from Pad 4 to a maximum downhole depth of 636.3 metres
and was designed to test multiple zones of CBM veins overprinting
the mineralized breccia in the central eastern side of the deposit
where limited information was available in the block model. The
drill hole intercepted porphyry mineralization with CBM sheeted
veins overprinting in part at shallow downhole depths before
passing into mineralized breccia at a downhole depth of 226.80
metres (220 metres vertical). Continuous porphyry mineralization
with overprinting sheeted CBM vein material was observed in the
breccia until 534.40 metres downhole. The mineralized breccia's
sulphide matrix hosts chalcopyrite (1%), pyrite (1%-2.5%) plus some
pyrrhotite with multiple zones of sphalerite and galena observed.
Three principal high-grade zones were intersected at downhole
depths of 233.15 metres to 261.50 metres, 354.40 metres to 372.20
metres and 396.00 metres to 413.10 metres with assay results for
the complete hole as follows:
- 307.60 metres @ 2.53 g/t gold equivalent from 226.80 metres
downhole (consisting of 1.40 g/t gold, 53 g/t silver and 0.25%
copper) including:
-
- 28.35 metres @ 5.06 g/t gold equivalent from 233.15 metres
downhole in a sheeted CBM zone;
- 17.80 metres @ 4.81 g/t gold equivalent from 354.40 metres
downhole in a sheeted CBM zone; and
- 17.10 metres @ 6.62 g/t gold equivalent from 396.00 metres
downhole in a sheeted CBM zone.
APC-48 was drilled steeply (-75°) in a
southwesterly direction from Pad 7 to a maximum downhole depth of
354.55 metres and was designed to test the potential of
mineralization outside of the breccia to the southwest. The
mineralized interval of oxidation commenced from surface to 12.40
metres and consists of saprolite followed by a transition zone down
to 39.55 metres. The transition zone hosts iron oxides formed from
the oxidation of the original sulphides hosted within the matrix of
the breccia and within veins. Below the zone of oxidation, the
intercept passed into fresh rock consisting of quartz diorite
breccia with a matrix of chalcopyrite (0.8%), pyrite (up to 2.5%)
and 1% pyrrhotite. A high-grade zone was encountered within the
transition zone from 13.15 metres to 31.40 metres downhole with
numerous sheeted CBM veins overprinting the breccia matrix. APC-48
exited the mineralized breccia at 114.40 metres (112 metres
vertical) and entered a mineralized precursor stage of porphyry
mineralization from 128.10 metres to 236.70 metres grading 0.40 g/t
gold equivalent over 108.60 metres. APC-48 is notable for extending
the maximum known strike length of the Apollo system by 50 metres
to the southwest with the maximum known overall system dimensions
now measuring 435 metres x 395 metres x 915 metres. Assay results
for APC-48 are as follows:
- 114.40 metres @ 2.38 g/t gold equivalent commencing from
surface (consisting of 1.71 g/t gold, 15 g/t silver and 0.29%
copper) and including:
-
- 12.40 metres @ 1.65 g/t gold equivalent in oxide and
transition zones from surface; and
- 18.25 metres @ 6.32 g/t gold equivalent from 13.15 metres
downhole in a sheeted CBM zone.
Visual Observations for Drill
Holes APC-49 and APC-55 (see Figure 1)
Two step out drill holes were recently completed
from Pad 6. APC-49 was drilled to the northwest and encountered
over 840 metres of continuous, downhole mineralization from
surface. The hole contains an upper zone rich in chalcopyrite (up
to 1.5%) to 300 metres downhole and below that multiple zones with
overprinting CBM veins were encountered. The hole was stopped at
852.90 metres (900 metres vertical) while still in mineralized
breccia due to drilling related challenges.
Drill hole APC-55 was drilled to the northeast
from Pad 10 and also intersected continuous mineralization from
surface to a downhole depth of 790 metres (752 metres vertical).
The upper portion of the intercept (to 400 metres downhole depth)
contains strong chalcopyrite mineralization of up to 1.5% in the
breccia matrix as well as overprinting CBM veins. Below 400 metres,
the hole continues in mineralized breccia including various zones
of sulphide rich CBM veins and veinlets containing high amounts of
sphalerite and galena. APC-55 has the potential to extend the
Apollo porphyry system to the northeast and again highlights the
presence of multiple CBM zones in the northeast and eastern sector
of the Apollo deposit below the copper rich zone. The Company plans
to undertake directional drilling in this area.
Apollo Drill Program
Eleven additional holes have been completed at
the Apollo system with assay results expected in the near term. All
holes intersected bulk tonnage mineralization over significant core
lengths.
The Company presently has three diamond drill
rigs operating at the Apollo project. A fourth drill rig is
expected to be at the project in June
2023 and is going to test new exploration targets identified
around Apollo as well as other targets at the Guayabales
project.
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. (see press release dated April 18, 2023)
