Gold Bull Resources Corp. (TSX-V: GBRC)
(“Gold Bull” or the “Company”) is
pleased to report results of ongoing exploration targeting field
work completed at its Sandman project, located in Nevada, USA.
- New silver target emerges
at K8 Prospect
- New prospect and drill
target defined at "Abel Knoll South"
A new drill target has been identified via a
surface lag sampling geochemical anomaly, located south of the Abel
Knoll diatreme breccia where the Sandman North-West and North
Trends intersect, at a new prospect referred to as "Abel Knoll -
South". The drill target is located 120m south of the Abel Knoll
diatreme breccia deposit and coincides with a geophysical anomaly.
The target has never been drilled.
At the K8 prospect, surface rock chip sampling
returned encouraging results of high-grade gold (Au) and silver
(Ag) with grades up to 1.11g/t Au and 210g/t Ag
(sample 6R) and a cluster of anomalous surface rock chip samples
spaced 150m apart. In this area there are sparce historical soil
samples and drill holes which require further assessment at K8 to
determine if the sampling is adequate given the high amount of
unconsolidated sand at surface and compelling new data.
Gold Bull’s CEO, Cherie Leeden said:
"While the capital markets remain difficult, our
geology team is working on defining new drill targets at Sandman,
to be tested when the capital markets improve. This is being
achieved via a combination of boots on ground field work combined
with reviewing the extensive historical data base that we acquired
with Sandman (valued at circa US$30 million if we were to re-do the
work at the current costs).
At the newly identified Abel Knoll South
prospect the coincident lag geochemical anomaly with the
geophysical anomaly gives us confidence in needing to drill test
this new target. Given Sandman's Mineral Resources were not closed
off when Gold Bull conducted its Preliminary Economic Study (PEA),
the possibility of a further mineralized diatreme breccias located
around the Abel Knoll resource is an exciting possibility,
especially with nearby historical holes logged as containing
portions of breccia.
At the K8 prospect, rock chip samples have
returned high very high silver results of up to 210g/t Ag with high
gold grades of up to 1.11g/t gold from surface rock chip sampling
of a granodiorite! Further evaluation work of historical soil and
auger work is required to define drill targets at this compelling
North-West Trend location.
In parallel to our exploration targeting work,
we are extensively evaluating inbound M&A interest."

sampling at Abel Knoll and rock chip sampling from K8 prospect.
Figure 2. Location of the Abel
Knoll deposit and lag sampling lines and location of the rock chip
samples taken at K8 prospect. The lag samples were taken west and
south of the Abel Knoll deposit as an orientation survey to
determine if anomalous coarse rock existed surrounding the deposit
which has not had step-out nor sterilization drilling
conducted.
Abel Knoll South - New Drill
TargetOrientation lag sample testing was conducted west
and south of the Abel Knoll deposit in search of path finder
elements as a cheaper method of near surface testing to yield drill
targets which are expensive to conduct. Lag sampling is designed to
confirm if further gold anomalism can be found within the coarse
fraction of alluvium which is roughly approximate to the sample
location point and is used to test larger areas for submerged
deposits represented by dispersed anomalism. The key to lag
sampling is understanding the substratum and classifying as near
situ or transported alluvium. Using the location of lag anomalies
is a good additional geochemical exploration tool when targeting
drill testing holes from processed geophysics, it basically gives
more confidence to warrant drill testing which is expensive to
conduct.
Lag samples were taken as coarse sieved
fractions over the three lines whereby the fine sand fraction was
discarded, and the coarse fraction was analyzed. Analysis was
conducted initially using a field portable XRF machine which
yielded elevated arsenic levels, and these samples were then sent
to the laboratory for testing and confirmed the high arsenic
anomalous area immediately south of the Abel Knoll diatreme
breccia. The gold and arsenic values reported in this announcement
are certified laboratory results. A single lag sample returned
elevated gold with 0.50ppm (sample 53) however is interpreted as a
single outlier and not an anomaly due low arsenic 11ppm, no repeat
of results in surrounding samples, the presence of quartz float in
the sample, and located in the deeper basin area where coarse
fraction return was poor so likely transported quartz mineralized
piece.
The results of the lag arsenic analysis is
anomalous as the arsenic levels were consistent over multiple
samples, and altered coarse rock pieces logged in the sample, and
arsenic is associated with gold at the Sandman project i.e. there
is a consistent association with gold and arsenic at Sandman. The
arsenic target area coincides with the intersection of the 11.5km
North-West and 10km North Trends and shows a separate geophysical
anomaly in the processed gradient array apparent resistivity
geophysical imagery (figure 5).
Drill holes are sparse surrounding the Abel
Knoll deposit which has no step-out drilling, nor has had
sterilization drilling conducted surrounding the deposit so there
is prospectivity to discover more mineralized diatreme breccias
near to the existing Abel Knoll breccia and this is why the lag
orientation sampling was planned and conducted as the diatreme
breccia hosts high grade gold up to 2ppm in drill results. Figures
4 and 5 show the lack of drill testing surrounding the Abel Knoll
deposit due to the lack of outcrop surrounding the deposit.

deposit. Background TEM (transient/time-domain electromagnetics)
image and interpreted 11.5km North-West Trend and 10km North Trend
are shown and both intersect in the location of the Abel Knoll
deposit. Curiously the 11.5km North-West Trend dissects the western
Abel Knoll breccia from the eastern Tertiary basalt and sedimentary
succession gold mineralization (the eastern larger portion of the
deposit). The lag sampling is anomalous in arsenic which is
characteristically associated with gold mineralization at Sandman.
The location of sample 53 (0.50ppm Au) is the 4th sample from the
west on the second lag sample line.

(-50m) processed image with lag sampling coinciding with
geophysical anomalies along the 10km North-Trend (range front
fault) and intersection with the 11.5km North-West Trend at the
Abel Knoll deposit. Another target exists to the north of Abel
Knoll which also requires future lag sample testing. The depth of
basin to the west gets deeper in the green-blue area and this area
was not successful for lag sample testing as it was difficult to
obtain sufficient coarse sample for analysis as sample becomes
mostly transported fines, this is when the geologist knows the area
has not been successful for lag sample testing.
K8 Prospect - new silver target within
the North-West Trend
Surface rock chip samples were taken at the K8
prospect, and the best grade returned from a certified laboratory
was 1.11ppm Au and 210ppm Ag from a surface rock
chip sample (ID 6R) containing iron altered granodiorite
(hornblende) rock and massive quartz veining. Numerous elevated
gold and silver rock chip samples returned from the laboratory
include: 0.81ppm Au and 45.1ppm Ag (ID 5R),
0.84ppm Au and 5.9ppm Ag (ID 1R) and
0.19ppm Au and 30.2 ppm Ag (ID 7R) and
0.14ppm Au and 20.4ppm Ag(ID 9R). The rock chip
samples were taken from an outcrop which exhibited jarosite iron
staining with liesegang banding after sulfide (most likely pyrite)
with some iron-stained quartz veining within a granodiorite rock.
The iron alteration was evident with alteration along the conjugate
joint sets and banding reminiscent of liesegang after sulfide.
The silver is considered very high grade for Sandman
returning up to 210ppm silver (ID 6R with GRAVAg30 analysis) and
there is also widespread elevated silver values noted in the
historical soil samples which need further evaluation as to the
grade potential. Silver is known to exist at the Sandman
project in association with the gold mineralization, however,
silver has not been included in the previously reported Mineral
Resource Estimates (MRE) due to inconsistent and incomplete
collection of laboratory silver analysis by previous explorers
during their drill analytical work. No high-grade silver has
previously been reported, possibly due to a lack of historical
analysis of silver at Sandman. The host rock at K8 Prospect is
altered granodiorite and contains sparse historical drill
holes.

subcropping quartz vein, a portion included in sample 6R, which
returned 1.11ppm gold and 210ppm silver.
The rock chip samples were taken from an area
previously tested with soil and auger sampling, however, field
observation yielded interesting rocks which had not been previously
rock chip sampled. The historical soil sampling identified an
anomalous area measuring 1.5km length within the North-West Trend
defined by >0.01ppm gold from soil and auger samples. Only four
historical drill holes were drilled within a 217m diameter cluster
and intersected Cretaceous granodiorite in hole K804-0001 which
averaged highly anomalous 0.15ppm gold for the entire hole for
103.6m, hole K804-0002 averaged 0.21ppm gold over the entire hole
121.9m, hole K804-0003 averaged 0.11ppm gold over the entire hole
120.4m and hole NSM-00379 averaged 0.15ppm gold over the entire
hole 146.3m. Best historical gold intersections include NSM-00379
48.7m @ 0.32ppm Au from 28.9m including 7.62m @ 0.80ppm Au from
33.5m, from hole K804-0001 18.3m @ 0.45ppm Au from 85.3m (to end of
hole) including 4.5m @ 1.12ppm Au from 94m, from hole K804-0003
15.2m @ 0.33ppm gold from 12.2m.
The K8 prospect has previously been downgraded
due to the cluster of drilling intersecting low grade gold in
granodiorite within a 217m radius, however the soil
geochemical strike length is 1.5km and lies within the
North West Trend which extends to the Abel Knoll deposit in the
southwest and all the way to the North Hill deposit to the
northwest, the total strike length of the Northwest Trend at the
Sandman project is 11.5km. The high-grade silver returned from
samples 6R warrants further evaluation of this prospect
particularly detailed evaluation of the surface geochemistry and
its silver potential.
Further detailed assessment of the historical
soil and auger sampling and some older ground VLF-EM (very low
frequency electromagnetic) surveys need orientation to confirm if
the new targets warrant drill testing, in the previously
interpreted large low grade K8 gold prospect.
Photo 4. Photo facing west
along the 11.5km North-West Trend showing the K8 prospect area in
red broken line. The target area includes the upper slope area
where the jarositic altered granodiorite with quartz veining is
outcropping and the downslope area has fine sands at surface. This
area is likely very suitable for lag surface sampling and analysis
for arsenic with a field portable XRF machine as a first pass
low-cost assessment.
Sandman Drill TargetsSandman
now has two new drill ready targets, the first being at Abel Knoll
South which was defined by the recent lag sample orientation test
work which returned a consistent arsenic anomaly which coincides
with a gradient array apparent resistivity anomaly. Further lag
sampling is also warranted on a similar target to the north and
another area of geophysical interest located northwest of the Abel
Knoll breccia.
A former target previously reported, that
requires further ground geophysical surveying for drill targeting
is the Silica Valley target which is located immediately northeast
of the Silica Ridge deposit. Multiple targets warrant further
exploration follow-up work to discover additional gold ounces. In
addition, the Sandman Mineral Resource Estimates has not been
completely closed off, nor has step-out and sterilization drilling
been conducted as is normally the case prior to reporting
Preliminary Economic Assessments.

operating gold mines and mineral resources. Reference to the nearby
projects is for information purposes only and there are no
assurances the Company will achieve the same results.
NEXT STEPS
Further evaluation of the historical soil and
auger sampling at the K8 prospect is required to conclude potential
drill targets and to evaluate the potential of high silver within
the granodiorite host rock. Evaluation of historical soil and other
ground geophysical surveys at Abel Knoll, Silica Valley and the
southern area of North Hill is required to conclude a list of
high-quality drill targets aimed at a new gold deposit discovery
within the Sandman tenure.
ABOUT SLEEPER 23kms NORTH OF
SANDMAN
The Sleeper-Sandman corridor is a highly endowed
and underexplored terrain given the Sleeper Mine mined circa 2
million ounces of gold (plus 2.3 million ounces of silver) and had
an approximate Measured and Indicated Mineral Resource of 3 million
gold equivalent ounces at the time of mining. The mine is located
circa 23 kilometers north of Sandman’s North Hill deposit along the
same Nevada gold trend. The Sleeper deposit measures 500m wide by
2km in strike length and was one of the highest-grade gold deposits
mined in Nevada at 0.48opt (15ppm) gold. Sleeper had a reportable
resource of 2.27 million ounces of gold in 1997 at the time of mine
closure. The deposit was obscured by cover because it was partially
covered by alluvium to the west and was not all outcropping. This
highly prospective corridor has been massively underexplored and
under drilled given the prolific known gold mineralization at or
near surface in the district.
It should be noted, it took Sleeper thirty-four
(34) step-out drill holes to discover the high-grade gold vein
system with the discovery hole returning 102m of silicified breccia
that averaged 28 ppm gold and 62 ppm silver. A very persistent
exploration methodology was applied by Gold Bull’s current
Technical Advisor, John Wood, who is credited to discovering the
high-grade Sleeper deposit (Wood pit named after him) which was
surrounded by lower grade disseminated gold. The Sleeper anomaly
had an initial surface geochemical expression 50-300m wide and
1,000m long, surface samples ran 0.2ppm gold and mineralization
remains below the historical pit. A similar narrow surface
expression also exists at the Sandman Southeast Pediment deposit
and therefore it is considered possible to discover an additional
deposit outside the existing Sandman orebodies.
ABOUT SANDMAN
In December 2020, Gold Bull purchased the
Sandman Project from Newmont. Gold mineralization was first
discovered at Sandman in 1987 by Kennecott and the project has been
intermittently explored since then. There are four known pit
constrained gold resources located within the Sandman Project,
consisting of 21.8Mt at 0.7ppm gold for 494,000 ounces of gold;
comprising of an Indicated Resource of 18,550kt at 0.73ppm gold for
433kozs of gold plus an Inferred Resource of 3,246kt at 0.58ppm
gold for 61kozs of gold. Several of the resources remain open in
multiple directions and the bulk of the historical drilling has
been conducted to a depth of less than 100m. Sandman is
conveniently located circa 25-30 km northwest of the mining town of
Winnemucca, Nevada.
