VANCOUVER, BC, Dec. 23, 2020 /CNW/ - Cache Exploration Inc.
(the "Company" or "Cache") (TSXV: CAY) (OTC Pinksheet:
CEXPF) is pleased to announce the results from metallurgical
tests from the Rusty Zone at the Kiyuk Lake gold project,
Nunavut.
The previously reported intercept of 8m @ 26.4 g/t Au reported from KI17-001 from 2017
summer drilling in the Rusty zone was submitted to SGS Laboratories
for metallurgical testing and screen metallics. Cache is please to
report that leachwell active accelerated cyanide leach testing
returned an average of 98% free gold recovery from the
intercept.
Both leachwell and metallic screens yielded slightly lower Au
values over the intercept of 21.5 g/t Au and 24.2 g/t Au
respectively. These values are lower compared to the original 50 g
fire assay results, but these lower values are considered to be
more precise estimates of the Au content of the sample. Regardless,
they confirm the high-grade nature of the Au intersection
examined.
Jack Bal, CEO of Cache
Exploration Inc, states "The 98% free gold recovery tell us the
metallurgy of Kiyuk Lake is mainly free gold. This simplifies the
metallurgy of the deposit and lowers the cost of recovery of Gold.
We are extremely pleased with the upcoming drill program"

Summary of Analysis:
A 1 kg split of coarse reject material from a selected
high-grade intersection was pulverized at SGS Red Lake.
Approximately 400 g of this material underwent screened metallic
fire assay at Red Lake using a 200
mesh (75 micron) screen, with a duplicate 50 g fire assay of the
-200 mesh material (method GO FAS30k). The +200 mesh material was
fire assayed in total. The assay results are weighted by the
respective weights of the +200 and -200 grain size fractions to
calculate a total Au value for each sample. 500 g of material was
also sent to SGS in Burnaby for an
active accelerated cyanide leach (Leachwell method code GE LWL69K).
After tumbling for 24 hours, an organic solvent (DIBK) was added to
extract the Au and the solvent analyzed using AAS. This assay gives
the concentration of free Au in the sample that can be extracted
using cyanide. A 50 g fire assay of the tails gives the
concentration of Au that was not dissolved in the cyanide.
Combined, the two values give a bulk Au assay for the 500 g sample,
as well as the proportion of free to encapsulated Au in the sample
for the pulverization used. In this instance nearly 100% of all Au
in the sample was liberated during pulverization and was available
to be taken up by the cyanide solution.
Rusty Zone
Drilling at the Rusty zone will be focused
on offsetting the high-grade gold intercepts in 2017 and expanding
the disseminated gold mineralization at depth and at surface to the
south and east. Drilling in 2013 and 2017 demonstrated strong
continuity of breccia-hosted gold mineralization within the Rusty
zone.
Highlights from previous drilling at Rusty include:
- 8.0m at 26.4 g/t Au from
108m
- 52.4 m at 3.2 g/t Au from
surface
- 35.9 m at 4.9 g/t Au from
134.1 m
- 61.5 m at 3.3 g/t Au from
159 m
- 122.0m at 1.8 g/t Au from
188m
Gold Point Zone & East Gold Point Discovery
The
Gold Point zone is a high priority target located in a 24 kilometre
magnetic anomaly coinciding with a polymictic conglomerate that
will receive further drilling in this program. Ground
magnetics, prospecting and mapping in 2012 and 2013 identified a
possible extension of Gold Point mineralization by the discovery of
similar mineralization, in boulders, in the polymictic conglomerate
that hosts the Gold Point zone. These extensional zones - South
Gold Point and East Gold Point respectively - were further defined
by ground magnetics as zones of magnetite destruction coincident
with east-west structures, which are identical to those found at
the Gold Point zone. Drilling in 2017 resulted in a new
discovery at East Gold Point. Drilling in 2021 will focus on
expanding East Gold Point and discovery drilling at South Gold
Point in addition to the expansion drilling at Gold
Point.
Previous drilling at the Gold Point zone returned:
- 63.6 m at 2.84 g/t Au from
148 m
- 12 m at 2.4 g/t Au from
120 m
- 12 m at 3.9 g/t Au from
163.5 m
East Gold Point, is located 700m
to the east of the Gold Point zone. This previously untested target
was defined by coincidence of magnetite destructive features
observed in ground magnetic data and the presence of mineralized
boulders on surface. East Gold Point represents a 'proof of
concept' new discovery that confirms the prospective potential of
structures that cross cut the polymictic conglomerate unit. Success
in intercepting significant gold mineralization in the first drill
hole to target the northern most extent of this structure is a
positive result for further development of gold mineralization
models at the Kiyuk Lake project. The strike length of the
magnetite destructive features is yet to be determined and will
require further ground magnetic surveying to define and constrain
their extent.
Drilling at the East Gold Point returned:
- 64.0 m at 1.46 g/t Au from
35 m
- 10 m at 6.5 g/t Au from
248 m
About Cache Exploration
Cache Exploration is focused
on its Kiyuk Lake gold project in Nunavut. Kiyuk Lake is a true district play in
a new gold camp, covering a majority proportion of the Proterozoic
Kiyuk Basin. The property has seen 13,500 meters of drilling in 4
drill programs from 2008-2017. Gold Showings occur over 15 Km
in the basin. Drilling has discovered multiple gold intercepts over
1 g/t Au in five discrete mineralized zones Rusty, Gold Point, East
Gold Point, Cobalt and Amundsen. Significant expansion possible
with five new target areas identified and ready for drilling.
Exploration at Kiyuk Lake takes place in winter-spring (February –
May) and summer-fall (June-October).
