XAU Resources Inc. Announces Positive Results from Stream Sampling on Noseno Property, Guyana
XAU Resources Inc. Announces Positive Results from Stream Sampling on Noseno Property, Guyana
TORONTO, April 12, 202 3– XAU Resources Inc. (" XAU" or the " Corporation") (TSXV: GIG. V), is
pleased to announce that it has received positive results from the bulk leach extractable gold (BLEG) stream
sediments sampling program conducted on its Noseno property in northwest Guyana. The sampling program
was successful in highlighting several areas with significant gold anomalism corresponding to f avourable
geology which warrants follow up exploration (Figure 1).
Results Highlights
The field sampling team collect ed 142 samples from early fall through to December of which 9 samples
(95th percentile) returned BLEG values greater than 60ppb up to a high of 141ppb gold, and 27 samples
(80th percentile) returned values greater than 45ppb gold. (Figure 1).
“We are pleased with the encouraging results of our BLEG program as the anomalous samples confirm
geologically prospective areas (target areas 1 to 3) . We look forward to continuing our sampling in the
southeast and southwest corners of the Noseno property as well as first -pass soil sampling over the most
prospective target areas identified by the recent BLEG program in our next exploration campaign,” stated
Peter Hambro, Chairman of XAU Resources.
XAU BLEG Stream Sediment Sampling Program
The program’s goal was to obtain stream sediment samples from stream drainage channels across the Noseno
property as a first -pass assessment of the geological potential of the property to host significant gold
mineralization. The survey method chosen, the “bulk leach extractable gold” also known as “BLEG”- style
of stream sediment sampling and analysis was selected because the method is an extremely sensitive gold
detection technique that can detect gold values down to one part per billion and can distinguish traces of
gold in stream sediments up to 10 kilometres downstream of mineralization. Subsamples were also submitted
for ICP multi -element analysis to determine enrichment in other economic and pathfinder elements
potentially associated with gold. The results and methodologies are explained below.
Results
The anomalous sample results are clustered in several parts of the property validating perceived areas of
geological prospectivity (Figure 2). The strongest anomalism occurs in the northeast part of the property
(target area 1) , along the interpreted strike of the Noseno prospect where previous explorers Riva Gold
Corporation conducted a limited diamond drilling program (2010) that returned up to 1.63 metres of 98.89
g/t Au (uncut), including 0.5 metres of 273.69 g/t Au¹ from quartz veining in sheared, altered amphibolite.
No formal exploration on or near the Noseno property has been undertaken since then.

Target area 2 is second highest in gold tenor occurring over the central part of the property where a smaller
granitoid has intruded the middle of the Noseno district greenstone rocks. Target area 3 sits on the
southeastern flank of the property along a n approximately north-south trending granite contact, and target
area 4 is situated in the northwestern corner of the property over volcano-sedimentary rocks.
Geological observations made during the sampling program noted outcrops of mafic, andesitic, and
porphyritic volcanics, intermediate to felsic volcanics, arenites, siltstones and mudstones plus granite,
diorite, gabbro and feldspar porphyry; a diverse assemblage of geology. Shearing and quartz veining was
also locally observed, as were large extents of presently inactive historical alluvial workings up to several
kilometers long. Prospecting yielded 19 rock chip samples as the focus of the field teams was to complete
the stream sediment sampling program before Christmas. Rock chip sample a ssays returned weakly
anomalous gold with one sample from quartz rubble at an artisanal site returning a value of 99ppb gold.
The results of the ICP multi-element analysis of the stream sediment samples did not return significant
anomalism in other elements and the correlations between gold and typical orogenic -gold pathfinder
elements was weak.
The Noseno stream sediment sampl e gold anomalism coinc ident with areas of interpreted geological
prospectivity is encouraging such that future work programs will include first-pass soil sampling over the
most prospective target areas 1 through 3 . In addition, the southwest and southeast areas that were not
accessed will be sampled during the next program.
Sampling and Analytical Methodology, QA/QC
The stream sediment sampling program at Noseno utilized a “BLEG”-style sampling and analytical method.
Very fine stream sediments were sampled from the quieter sections of active stream channels and coarse -
sieved on site with a 12-mesh screen.
The samples were bagged and kept secure in the Noseno camp until the end of the program, and from there
the samples were securely transported under XAU Resources staff supervision by ATV and truck to Port
Kaituma and then shipped to Georgetown. Samples were submitted to Actlabs in Georgetown for BLEG
(bulk leach extractable gold) analysis.
Actlabs is an ISO9001-2015 certified laboratory. At Actlabs the stream sediment samples were dried, sieved,
crushed and pulverized to 95% passing 105 μm, and a 1kg split was bottle-rolled in cyanide solution for 24
hours with the gold concentration of the solution measured by AA (atomic absorption) with a lower detection
limit of 3 ppb Au.
In addition to the BLEG Au analyses on the Noseno stream sediment samples, 4-acid digestion ICP-OES
(induced coupled plasma -optical emission spec troscopy) was conducted on the samples for 36 trace
elements. Subsamples of approximately 30g of the processed stream sediment samples were obtained at the
Actlabs laboratory in Georgetown prior to BLEG analysis and the se were then shipped to the Actlabs
laboratory in Zacatecas, Mexico for ICP-OES analysis. The rock chip samples collected from Noseno were
analyzed at Actlabs laboratory in Georgetown by 30g Fire Assay and atomic absorption (AA) finish.
For the QA/QC protocol , certified standards and blanks (from OREAS) and field duplicate samples were
inserted into the sample stream at a rate of approximately one in eight samples. A total of seven standards
and six blanks were used and six field duplicate samples were obtained for a total of 19 QA/QC samples in
142 stream sediment samples. The QA/QC results were determined to be acceptable. There were no QA/QC
reference materials used in the analysis of the rock chip samples, as the total number of samples was 19 and
the final assays results were less than anomalous.
