DIEPPE, NB, Dec. 3, 2019
/CNW/ - (CBI-TSXV) Colibri Resource Corporation ("Colibri" or the
"Company") is pleased to announce that it has received the
sample results from its field geology study conducted by
AuroMetallum Geology Consulting Services. The highest value
received was from a chip sample which measured 40.1 ppm Au from a
quartz vein containing boxwork, pyrite, and goethite.
The team which conducted the study in October 2019 submitted a total of 100 samples to
the Hermosillo, Mexico office of
ALS Chemex Labs. Of the 100 samples submitted, 91 samples were
taken from exposed outcrop and subcrops in the areas of study, 5
samples were duplicates and another 4 were standards.
|
Of the samples
taken:
|
81 have grades
>.005 ppm Au (89.0%)
|
|
30 have grades
>0.10 ppm Au (33.0%)
|
|
24 have grades
>0.20 ppm Au (26.4%)
|
|
12 have grades
>0.75 ppm Au (13.2%)
|
The samples were analyzed for 34 elements including gold,
silver, arsenic, bismuth, lead and copper. Arsenic, lead, and
bismuth are understood to be key pathfinder elements in tracing
gold in orogenic structures in the Caborca gold belt including the
economically significant mines at Noche
Buena and La Herradura.
Many of the higher grade gold samples taken at Evelyn also have
elevated arsenic, lead and bismuth values.
The results of this sampling program provided additional
confidence that the structural and geological mapping has indeed
identified at least two separate corridors of favourable NW/SE
structure with surface expressions of anomalous gold. The study
areas have now been named: Cerro
Rojo and La Sahuaro. See illustration below. These
identified zones also correspond with anomalous soil samples taken
in 2011/2012 (See Company website:
www.colibriresource.com/projects/evelyn).

With samples in hand in combination with the geological &
structural mapping, Colibri now feels confident moving forward with
its planned drilling program of up to 1000 meters at Evelyn.
Permits are being applied for and drilling companies are being
contacted for quotations. The Company will provide guidance to the
market as permits are received and when a drilling contract has
been awarded.
The Company has enough cash on-hand to complete this drilling
program.
Evelyn Map
Sampling, Analyses, and QAQC
The samples collected during the field work and reported here
are grab samples of out-crop and sub-crop. Grab samples are
not representative of any volume (tonnage) of potential
mineralization on the property. The grab samples, which may
not be representative of metal grades, were collected as part of
the on-going exploration effort to determine the Au and Ag contents
of various rock types on the respective property. The assays were
completed at ALS Vancouver Canada after being submitted to the ALS
laboratory in Hermosillo,
Sonora. Industry standard sample preparation and analytical
techniques were used. The ALS sample preparation procedures
used include crushing the entire sample to 70% passing 2 mm and
pulverizing a 250 g split of the crushed sample to 85% passing 75
microns. Au determination was by fire assay on a 30 g sample
of the pulverized sample and AAS analysis. The high grade Au
samples from Evelyn were determined with a gravimetric
finish. Ag was determined on all of the samples by aqua regia
digestion and AAS analysis on a 0.5 g sample of the pulverized
material. Ag samples returning over limit values (> 100
g/t) were re-run using an ICP-AES finish. Major, minor, and
trace elements were determined on a limited number of samples using
a four acid digestion with ICP-AES finish. QAQC implemented
by the Company includes the use of Certified Reference Materials
and the completion of duplicate analyses. All samples were in
the possession of Company geologist from collection to submission
at the ALS Laboratory in Hermosillo.
