VANCOUVER, BC, Oct. 26,
2022 /CNW/ - Tajiri Resources Corp. (the
"Company") (TSXV: TAJ) is delighted to report power auger drilling
at the K4 South Prospect, Reo Project, Burkina Faso has discovered, an
in-situ, top metre of saprolite, gold anomaly that has all
the hallmarks of an anomaly overlying a potentially large world
class gold deposit.
K4 South, located at the southern end of the Company's 1,200
km2 Reo Project in west-central Burkina Faso (Figure 1) is one of an extensive
cluster of prospects that were investigated by an ~ 18,000m auger drilling program conducted by the
Company between November 2020 and
May 20211. Technical
details of the program are given in the Appendix, but in brief the
auger drilling sampled the top metre of saprolite, below a variable
cover of in situ and transported lateritic soils and has
thus delineated bed rock/in-situ gold anomalism.

Key results of the auger drilling program at K4 South and
interpretation of the same based on existing extensive data sets
are as follows:
- K4 South presents as an extensive area of high tenor gold in
saprolite anomalism (Figure 2) which has returned multiple +100ppb
Au and numerous +250ppb and 500ppb Au results within an envelope
spanning ~1700m x 1000m. The peak
gold value returned was 9,201ppb Au (9.2g/t Au)
- In all key aspects of grade, size and continuity- the K4 South
gold anomaly is on par with other in-situ saprolite gold anomalies
that were initially delineated over what turned into multimillion
ounce West African gold deposits such as M1 South, Namdini, and
Banken NE (Figures 3-6 and Table 1 )
- The central third of the K4 South Anomaly is situated within
and around an extensive area (700 x 450m) of artisanal workings (Figure 7) which not
only demonstrate that the anomaly is under sampled to the east
(Figure 10) and has excellent potential to expand, but critically
the form of the workings outline a self-evidently a poly folded
gold system (Figures 7- 10) with last generation F3 fold axial
traces striking 015°-020°.
- Re-processed airborne magnetic data from a 100 metre line
spaced survey flown in 2010 and a 3D inversion of a 2013
IP/resistivity survey and trends visible in high resolution
satellite DEM imagery all support K4 South being a a poly-folded
gold system (Figures 12, 13 & 5) with at least two phases of
folding and likely three.
- The shape of the K4 South auger anomaly which was interpolated
by following lithological contacts interpreted from magnetic and IP
data also shows a poly-folded form ( Figures 5 & 10)
- In addition, along a broadly NNE striking 100km x 20km belt
centred on K4 South almost every artisanal working visible in
satellite imagery demonstrates a form that is controlled by the
interplay between F2 and F3 fold generations examples given in
Figures 16A & B). This district level similarity of gold
mineralisation style along with all other data makes the
interpretation of K4 South as a poly-folded gold system almost
indisputable.
- Historic drilling of the K4 South gold anomaly and associated
artisanal workings is now seen to have been mostly ineffective with
drilling confined to the periphery of the anomaly and being poorly
oriented to test the poly-folded mineralisation. Nonetheless,
historic drilling returned a few notable intercepts such as
4m @ 8.5g/t, 10m @ 3.5g/t and 36m @ 1.3g/t Au that at least demonstrate that K4
South hosts economic grades of gold mineralisation.
- The implications of K4 South being a poly-folded gold system
are far reaching and extremely positive.
-
- Poly folded deposits are in general rare with the Wassa deposit
located in southern Ghana being
the singular, other example known from the West African Craton.
- Globally poly-folded gold deposits though rare tend to be large
to immense e.g., Homestake ~62Moz, Telfer ~56Moz, Kibali ~23Moz,
Wassa 13Moz, & Haverion 9.4Moz.
- At Wassa, the best empirical comparative because it occurs
within the same geological terrane, gold mineralisation has been
dated to have first been hydrothermally emplaced at the earliest
phase of the Eburnean orogeny- the Eoeburnean and was thus
subsequently affected all following phases of the Eburnean
deformation event resulting in its poly-folded form.
- Other West African deposits interpreted to be of Eoeburnean age
and though shear hosted with some a fold influence, are the big
ones Obuasi, (49-80Moz (depending on whose estimate))
Bogoso-Prestea (17M Oz) and Ahafo
(15M Oz).
- While we do not know the age of mineralisation at K4 South,
given mineralisation has been affected by at least 2, likely 3
phases of Eburnean deformation it is probably of similar early
Eoeburnean age to Wassa and thus dates from the time of the most
prolific gold deposition event in the West African Craton.
- At Wassa, high grade mineralisation is concentrated in tight F3
isoclinal folds and to a lesser extent other F1 and F2 closures.
Folds often have extenuated limbs that exhibit weak and narrow
<10m gold mineralisation, whereas
mineralisation in fold closures is >3.0g/t, tends to be or in
excess of 25-30m thickness, has dip
extents of ~150-200m, and enormous
contiguous down plunge extents that exceed at least 2,000m.
- Assuming mineralisation at K4 South follows a similar
"blueprint" to that of Wassa, one might expect that much
mineralisation at K4 South will have been missed in areas outside
and some inside, the close spaced 25 x 25m auger grid that was used in the central part
of K4 South (diagonals on a 25m
square grid are 36m across).
- Using the Wassa blueprint, better auger results, combined with
magnetics and interpreted mineralised outlines from artisanal
workings give us several potential high-grade shoots, hosted in
fold closures which are ready to be drilled:
-
- a) the 9.2g/t F3 nugget pit area (Figure 7),
- b) Those shown in Figure 14
- c) The area around the 36m @
1.3g/t drill intersection (see Figure 11)
- d) The 250m strike length ~
50m wide zone of >500ppb Au auger
values with a peak value of 2,263ppb Au located at the southern end
of K4 South (Figure 2).
- Given the style of mineralisation at Wassa, with the bulk of
gold ounces being carried by small, high grade, fold hosted shoots,
Wassa packs a lot of ounces into a small surface footprint of only
1,200 x 700m, yet has a net endowment
of 13 Million ounces in an area of similar size to mineralisation
outlined by both auger anomalism and artisanal workings at K4 South
(Figure 17)
In summary the implication of K4 South being of similar size,
poly-folded form and potential age to the 13 Moz Wassa deposit are
extremely positive and K4 South clearly has superlative potential
to host a substantial gold discovery.
Chairman's Comments
"I'm pretty sure we have a monster on our hands. K4 South is our
first reported prospect investigated in our 2020-2021 auger
drilling campaign and it is just one of several prospects that are
likely cojoined within a very large poly-deformed gold system. We
look forward to describing results from the other prospects to you
shortly.
In our collectively >100 year careers in gold exploration and
mining, this is by far and away the most tantalisingly exciting
discovery we have made. While it was frustrating to await renewal
of tenure it has been worth the wait. The results and the visuals
presented here speak for themselves."

APPENDIX
Technical Details
Results reported today are from a program of ~ 18,000 metres
completed in 4,125 auger drillholes drilled between November 2020 and May
2021 at the K4-K5 Prospect. Auger drilling was conducted to
infill historic 400 x 100m spaced
saprolite auger sampling at varying infill grids; predominantly 200
x 50m regionally and 100 x
25m and 25 x 25m over the K4 South Target. Regional 200 x
50m lines were oriented NW-SE while
the 100 x 25m and 25 x 25m auger grids were oriented E-W.
Drilling with hollow stem power auger was conducted and
supervised by Sahara Natural Resources and whole samples of 1-4kg
were assayed by 50 gram fire assay with a DIBK extraction at SGS
laboratories, Ougadougo, Burkina
Faso along with standards, blanks and duplicates making up
10% of the assayed samples. Assay sensitivity was 1 ppb Au.
The top metre of textured saprolite was sampled and auger drill
holes ranged from 3 to 29m in depth.
As saprolite was sampled by our auger program and lateral chemical
dispersion of gold in saprolite in the Sahel region of West Africa appears to be minor, detected gold
anomalism should be in-situ as confirmed in places by
underlying historic RAB and RC drill results.
All samples will be subject to multielement analysis by XRF to
allow identification of elements consanguineous with gold
mineralisation and the discrimination of lithologies by major and
minor element associations.
Geology
K4 South is hosted by a package of siliciclastic and
volcanoclastic sediments, volcanics intruded by co-sanguineous
diorite and granodiorite sills. Volcanics are mostly dacites to
andesites with lessor basalts and rare rhyolite. However, due to
previous wide spaced historic drilling and lack of outcrop a
detailed lithological model for K4 South has not yet been
constructed, and though we have analysed all historic multielement
data to discriminate lithologies – given the now known poly-folded
geology correlation of wide spaced samples is not
