TORONTO, ON / ACCESSWIRE / October 13, 2021 /( )(OTC PINK:TTSRF)(FSE:A2D) (“Tartisan”, or the “Company”) is pleased to provide an additional update for the ongoing 10,000 metre diamond drilling program at the 100% owned Kenbridge Nickel Project located in the Kenora Mining District, Ontario.
Highlights include KB21-202 which intersected two nickel-copper zones at a drill depth of 663.0 metres and 693.7 metres. The two zones are interpreted to represent the downdip extension of the two horizons known as “Zone A and Zone B”, the zones intersected in holes KB21-198 and KB21-200. In KB21-202 Zone A returned 25.5 metres of 1.13% Ni and 0.61% Cu including higher grade intersections of 4.5 metres of 2.96% Ni and 1.66% Cu and 1.5 metres of 4.17% Ni and 2.14% Cu. This hole was targeted approximately 200 metres down dip of previously released hole KB21-198 which returned 25.6 metres of 1.03% Ni and 0.41% Cu (see press release October 7, 2021). In KB21-202, Zone B returned 13.5 metres of 0.25% Ni and 0.13% Cu.
Assay results for drill holes KB21-201 and 202 of the current drilling program are provided in the table below. Holes KB21-198 through KB21-200 have been previously reported.
Hole KB21-201 intersected one zone at a drill depth of 762.0 metres. Zone A returned 1.5 metres of 0.52% Ni and 0.22% Cu. This hole was targeted north of holes KB21-202 and KB21-198.
Time Domain Electromagnetic (TDEM) surveys have been completed on drill holes KB21-198 and KB21-200. Interpretation suggests that two parallel, steeply dipping, strongly conductive zones extend below the intersections from those holes. Hole KB21-202 appears to confirm this interpretation. Hole KB21-204 was targeted to test these same interpreted conductors approximately 200 metres down dip of KB21-202. The hole has been completed with assays pending. Hole KB21-203 has been suspended due to drill hole conditions. A geophysical crew has been mobilized to the site to survey holes KB21-199, 201, 202, and 204. The TDEM surveys will aid in guiding additional diamond drilling.
The current drill program is designed to target the down dip and along strike extension of the Kenbridge Ni-Cu Deposit. The Company additionally plans to test the Kenbridge North target with diamond drilling during the current drill campaign. The Kenbridge North target is located approximately 2.5 kilometres north of the Kenbridge Nickel Deposit and was identified from a ground based Time Domain Electromagnetic (TDEM) survey completed in early 2021. The Kenbridge North target is interpreted to represent similar rock types that host the Kenbridge Nickel Deposit. This combined with the EM signature, Kenbridge North is a high priority drill target similar to the Kenbridge Nickel Deposit model (SEDAR, May 5, 2021).
Section looking south. Green outline is the current Mineral Resource. Blue and purple are associated gabbro pyroxenite favorable host rocks. Hole 204 is located approximately 150m below the deepest drill hole intersection completed in the 1950’s (Drill hole K2011- 4.25% Ni over 3m)

Atico Produces 4.43 Million Pounds of Cu and 2,952 Ounces of Au in Q3 2021
VANCOUVER, British Columbia, Oct. 26, 2021 (GLOBE NEWSWIRE) — Atico Mining Corporation (the “Company” or “Atico”) (TSX.V: ATY | OTCQX: ATCMF)…
VANCOUVER, British Columbia, Oct. 26, 2021 (GLOBE NEWSWIRE) —(the “Company” or “Atico”) ( | OTCQX: ATCMF) announces its operating results for the three months ended September 30, 2021 from its El Roble mine. Production for the quarter totaled 4.43 million pounds of copper and 2,952 ounces of gold in concentrates, a decrease of 20% for copper and an increase of 19% for gold over the same period in 2020.
“The production results for the quarter, particularly for copper were slightly below our 2021 objectives while the mined and processed tonnes are back on track after a challenging first half of the year. The decrease in copper is mainly driven by a lower head grade, partially expected in the mine plan for the period although expected to improve in the last quarter of the year,” said Fernando E. Ganoza, CEO. “We will continue looking for opportunities to improve metal production in the fourth quarter, with the primary goal of delivering our 2021 production guidance while operations still remain on track for record revenues in the second half of the year.”
Third Quarter Operational Highlights
- Production of 4.43 million pounds of copper contained in concentrates; a decrease of 20% over Q3 2020.
- Production of 2,952 ounces of gold contained in concentrates; an increase of 19% over Q3 2020.
- Average processed tonnes per day of 919, an increase of 7% over Q3 2020.
- Copper head grade of 2.77%, a decrease of 26% over Q3 2020.
- Gold head grade of 1.98 grams per tonne; an increase of 2% over Q3 2020.
- Copper and gold recovery of 93.2% and 59.7%; an increase of 2% and 6% for copper and gold, respectively over Q3 2020.
Third Quarter Operational Review
Overall production was in line with Company budget for the third quarter. The decrease in copper production is mainly explained by the decrease in head grade, partially offset by improved recoveries and an increase in processed tonnes over the same period last year. The gold output slightly improved due to an improvement in gold head grade, recovery and an increase in processed tonnes relative to Q3-2020. The inverse relationship between copper and gold head grades production during this period is explained by the current mining sequence of the orebody. During this period last year, we were mining higher grade base metal areas which typically have lower precious metal content, while during this period we mined lower base metal grade areas with higher precious metal content.
The Company continues to closely monitor developments around the COVID-19 pandemic and continues to maintain strict preventative measures at the El Roble mine site, La Plata project, as well as our corporate offices to safeguard the health of its employees, while continuing to operate effectively and responsibly in its communities.

Mandalay Resources Corporation Reports High-Grade Gold Discovered at the Brown’s Prospect – 2 km From the Shepherd Discovery and Youle Mine
Brown’s prospect contains visible gold along two main mineralized trendsTORONTO, Oct. 26, 2021 (GLOBE NEWSWIRE) — Mandalay Resources Corporation ("Mandalay"…
Brown’s prospect contains visible gold along two main mineralized trends
TORONTO, Oct. 26, 2021 (GLOBE NEWSWIRE) —[/nxtlink] (“Mandalay” or the “Company”) ( [/nxtlink], OTCQB: MNDJF) is pleased to provide an update on the deep drilling campaign completed at the Brown’s Prospect at its Costerfield Operation (Victoria, Australia).
- 17-hole diamond drill program confirms the presence of a promising gold system at the Brown’s Prospect, 2 km east of the current mining operation at Youle.
- Drilling has identified two main mineralized trends exhibiting high-grade gold intercepts, including:
- 19.5 g/t gold over a true width of 1.01 m in BWN009, including;
- 38.4 g/t gold over a true width of 0.51 m and;
- 19.9 g/t gold over a true width of 1.70 m in BWN023, including;
- 158.4 g/t gold over a true width of 0.09 m and;
- 110.8 g/t gold over a true width of 0.16 m
- 19.5 g/t gold over a true width of 1.01 m in BWN009, including;
Note: Further intercept details can be found in Table 1 in the Appendix to this document.
Dominic Duffy, President and CEO of Mandalay, commented: “We are pleased to report encouraging results from our ongoing drill testing campaign at the Brown’s Prospect situated 2 km to the east of the Shepherd discovery and Youle mine. The most recent results confirm significant gold grades within fault hosted breccias along two mineralized trends, building on previous high-grade results seen and reported in 2020.”
Mr. Duffy continued, “Mineralization across the two trends has been tracked over a 200 m strike and 300 m vertical extent. The Felix trend is associated with the historic shallow Felix Brown mine and associated alluvial workings that played an important role in gold production during the 1890’s. However, the newly discovered Western Trend is not associated to the old workings and was unknown to previous explorers; it is therefore still open up dip to surface.”
Mr. Duffy concluded, “A strong increase in data resolution through this prospect has allowed us to improve our understanding of the structural complexity associated with the mineralized trends. We observe that the structural controls on the Brown’s mineral system could be likened to those that allowed the formation of the nearby million ounces Bendigo and Castlemaine gold deposits. This inference, along with the knowledge that the geological setting of the Central Costerfield line sits below the recent drilling success, provides further confidence that there is a more extensive, high-grade mineralization at depth.”
A video has been prepared by Mr. Chris Davis, Vice President of Operational Geology and Exploration, to further explain the information in this release. The video can be found on Mandalay’s website or by clicking here.”
Drilling Results and Interpretation
Early success was achieved on the initial five-hole drill testing program at Brown’s with BWN001 intercepting 14.5 g/t gold over true width of 1.27 m underneath the historic (approx. 1883-1894) Felix Brown Mine and paving the way for a more detailed testing campaign. Since the release of the initial two holes (June 22, 2020), a further 20 holes have been drilled to identify the nature and extent of gold mineralization at Brown’s Prospect (Figure 1). To date, this drilling has identified multiple high-grade intercepts in a sequence of tightly folded sandstone-dominated turbidites crosscut by three main “panel boundary” thrust faults. Gold mineralization is concentrated in the middle thrust panel within narrow, brecciated and sheared fault zones along two main mineralized trends (Figure 2).
Figure 1: Surface map of the Brown’s prospect, showing collar locations and drillhole traces. Coordinates are in GDA95 Zone 55:
The Felix Trend is a moderately west dipping trend parallel to the axial plane of the main Brown’s anticline, expressing at surface with the historically mined Felix Lode. Mineralized structures associated with this trend are typically steeply dipping quartz-stibnite bearing fault hosted breccias, with associated stockwork veining and wide pyrite halos. These structures have developed preferentially in hinge zones of the main Brown’s anticline, parallel to the axial planar cleavage. Visible gold is present in several intercepts along this trend. Mineralization along the Felix Trend has been identified over a vertical extent of 200 m and a strike extent of ~100 m; however, gold anomalism along this trend has been observed down to the Swallowtail Fault at a depth of approximately 300 m. An increase in gold grade observed between 1000 RL and 1100 RL may be caused by the interaction of the fault-hosted breccias with syn-to-post mineralization, northeast dipping faults. The anticipated potential for upgrade in this zone was demonstrated with an intercept of the highest grade yet seen at Brown’s, comprising an interval with two steep east dipping gold bearing breccias and quartz-stibnite veining grading at 19.9 g/t gold with trace amounts of antimony over a true thickness of 1.70 m in BWN023 (Figures 3 and 4).

Figure 4: Microphotographs of gold grains in the high-grade gold bearing quartz breccia grading at 110.7 g/t gold (0.16 m true width) in BWN023 at 223.77 m depth:
The Western Trend is a broadly subvertical corridor containing several high-grade intercepts that occur in structures that have developed across a secondary antiformal structure on the western limb of the Brown’s anticline. Like the Felix Trend, intercepts are characterized by quartz-stibnite fault-hosted breccias and veins with large pyrite alteration halos and in some cases visible gold. While mineralization along this trend has been identified over a vertical extent of approximately 100 m, the strike extent remains open and poorly constrained at this date. The Western Trend contains high-grade gold intercepts comparable to the Felix Trend, including a quartz-stibnite breccia with intense pyrite alteration grading 19.5 g/t gold and 2.4% antimony over a true thickness of 1.01 m in BWN009 (Figure 5).
Figure 5: Drill core photos of BWN009 high-grade gold intercept and gold grades for each sample:
Panel Boundary Faults
The panel boundary faults that control the mineralized structures at Brown’s Prospect are interpreted to predate mineralization and accommodate movement caused by shortening of the turbidite sequence. Minor fault reactivation during and after mineralization has been observed along these structures and drilling has identified areas of gold anomalism along them. The highest grade to date on a panel boundary fault was observed on the Metalmark Fault in BWN008 up-dip of the western trend, culminating in an intercept of 9.1 g/t gold over a 0.63 m true width. Mineralization has also been observed in the panel bounding Swallowtail Fault, the highest grade seen being 1.3 g/t gold over a true width of 0.67 m in BWN004. Excitingly, visible gold was also observed in the Swallowtail Fault in BWN002, confirming that the panel thrust faults bounding the mineralized middle thrust panel represent important pathways for the mineralized fluids. The Luna Fault, the deeper of the three panel boundary faults, exhibits intense sericitic alteration characteristic of a distal discharge of gold bearing hydrothermal fluids vectoring towards a gold rich fluid source at depth.
The Brown’s Prospect drilling program has demonstrated the presence of a promising mineral system extending at depth at the Brown’s prospect. Increasing levels of fold shortening compared to the central (Costerfield) line of lode has resulted in the formation of a strong fluid trapping environment and consequently, the distribution of the fault-hosted mineralized breccias is strongly controlled by fold geometry and bedding. Current interpretation suggests that this structural architecture may share similarities with the Bendigo and Castlemaine goldfields, which are found in a similar structural environment and exhibit similar controls on mineralization. Extension of the mineralized trends to the south, beyond the currently tested zone is expected based on the continuation of the north-south trending Brown’s anticline, as well as the presence of historically worked gold reef systems along-strike at the Robinson Prospect (press released June 22, 2020). A soil sampling and geochemistry program is currently underway to cover the entire eastern corridor and identify extension of the mineralised system to the south. In addition, surface drilling along the eastern corridor will continue in 2022, targeting depth and strike extensions, including the Robinson prospect.
Encouragingly, mineralized breccias in the middle thrust panel at the Brown’s Prospect may only represent the most surficial expression of a much more extensive mineral system at depth; district-scale structural and litho-stratigraphic modelling suggests that the geological and structural setting of the central corridor may be present at about 600 m depth under the tightly folded sequence of the Wapentake Formation turbidites. The depth continuation of the Brown’s mineral system may therefore be hosted in the same favourable lithostratigraphic environment that hosts classic Costerfield-style mineralization like that of the Youle and Cuffley deposits. Gold anomalism in two subvertical quartz breccias under the Luna fault intercepted in BWN010 provides additional evidence that such a domain may exist beneath the Brown’s prospect.

Drilling and Assaying
All diamond drill core was logged and sampled by Costerfield geologists. All samples were sent to On Site Laboratory Services (OSLS) in Bendigo, Victoria, Australia, for sample preparation and analysis by fire assay for gold, and Atomic Absorption Spectroscopy (AAS) for antimony. Samples featuring coarse grained visible gold were assayed using a variant of fire assay known as screen fire assay. This method is routinely used to mitigate potential problems associated with heterogeneity in the distribution of coarse gold within drill samples. The procedure collects all coarse heterogenous coarse gold by screening at 75µm after crushing and pulverisation, and subsequently fire assays the resultant mass to extinction. A mass weighted average of gold grade of the sample is subsequently calculated from the +75µm and -75µm fractions of the sample. Site geological and metallurgical personnel have implemented a QA/QC procedure that includes systematic submission of standard reference materials and blanks within batches of drill and face samples submitted for assay. Costerfield specific reference materials produced from Costerfield ore have been prepared and certified by Geostats Pty Ltd., a specialist laboratory quality control consultancy. See Technical Report entitled “Costerfield Operation, Victoria, Australia NI 43-101 Report” dated March 30, 2020, available on SEDAR (www.sedar.com) for a complete description of drilling, sampling, and assaying procedures.
