Timberline Resources Corporation (OTCQB:TLRS);(TSXV:TBR) ("Timberline" or the "Company") is pleased to report results from two more core holes from the 2021 drilling program at its 100%-controlled Eureka Project in Nevada. These are the final outstanding assays from the drill program, and they include one core hole in the Water Well Zone (WWZ) and the completed silver and multielement data from core hole BHSE-206C - totaling 861 meters of drilling.
The results from BHSE-192C confirm a significant zone of strong gold grades in the WWZ between drill holes BHSE-220C and BHSE-212C, which were reported during the first quarter (see Figure 1 and Company news releases dated February 24 and March 9, 2022). Highlights of the mineralization in BHSE-192C include:
- 24.4m at 3.85 grams per tonne (g/t) gold from 349.6 depth, including
- 4.6m at 8.35 g/t gold from 354.2m depth; and including
- 7.6m at 5.72 g/t gold from 364.8m depth.
The Company also received the complete analyses for silver (Ag) and other elements in drill hole BHSE-206C, from which the gold and partial multielement data were reported in a news release dated March 24, 2022. As previously reported, this hole included multiple intervals of anomalous gold, including 7.6m averaging 1.04 g/t and 86.9m of 0.16 g/t. However, the new analyses reveal that the drill hole is more mineralized in silver, lead (Pb), and zinc (Zn) than previously thought. One significant interval hosted by altered dolomite, breccias, and intrusive dikes included more than 202.7m that averaged 5.28 g/t Ag, including 56.4m averaging 9.69 g/t Ag, 0.17% Zn, and 0.11% Pb. This style of Ag-rich mineralization is believed by Timberline geologists to be older than the Carlin-type gold system, likely associated with Cretaceous-aged carbonate-replacement type deposits (CRD).
Patrick Highsmith, Timberline's President and CEO commented, "Drill hole BHSE-192C is an angled hole drilled into the Water Well Zone from the east. It is one of the first core holes to fill in between the high-grade results we reported last quarter. Our core drilling continues to confirm that the breccias at the base of the Dunderberg Shale are consistently mineralized over considerable thickness, but this hole also encountered strong gold grades in sheared and altered mudstones higher up in the Dunderberg. This result also extends the zone well to the east from previous drilling. Given the encouraging gold and silver associated with the IP anomaly in the Graben Zone farther east in BHSE-206C, we look forward to adding more core drilling in this area during the summer."
Figure 1 shows how the new results fit into the growing footprint of >3 g/t gold in the Water Well Zone. The long run of highly anomalous silver is also plotted along the trace of BHSE-206C. The IP anomaly occupies the graben between the Lookout-WWZ and Oswego gold occurrences, and it has yet to be tested at depth. Timberline expects to begin offsetting the new high-grade intercepts at the WWZ and near-surface gold at Oswego in June.

Geological Details and Interpretation
BHSE-192C was drilled on an azimuth of 300° at an initial inclination of -65°. The hole was designed to pass through an interpreted fault zone and penetrate the base of the east-dipping Dunderberg Shale. BHSE-206C was inclined -75° in a northeast direction (azimuth 050°) and designed to assess the upper reaches of the large IP chargeability anomaly identified in 2021.
Drillhole BHSE-192C was collared in the post-mineral volcanic rocks that occupy the Graben Zone east of the Lookout Mountain resource. The Cambrian-aged Windfall Formation was encountered at approximately 56m depth. The Windfall is a gray to orange (variably oxidized) thin-bedded limestone or silty-carbonate with frequent argillaceous layers or partings. In this area, the unit is highly faulted and brecciated, resulting in significant amounts of fault gouge and some core loss. The drillhole passed into the Dunderberg Shale at approximately 202m depth. The blue gray to greenish Dunderberg alternates between bedded and massive mudstone and is calcite-veined throughout. The upper portions of the unit exhibit frequent argillaceous partings and more reactive (carbonate-rich) bands. There is also ample evidence of faulting and brecciation. Fine-grained disseminated pyrite is first noted at approximately 210m depth, but there are several intervals of oxidation associated with faulting.
The gold zones occur near the base of the Dunderberg, but the highest-grade assays in the hole (13.75 g/t and 8.41 g/t Au) occur above the basal (carbonaceous and silicified) breccias that have characterized much of the WWZ. The upper zone of mineralization is associated with very fine-grained argillaceous mudstones that are sheared and brecciated, but not highly silicified or carbonaceous. The contact with the underlying Hamburg Dolomite is marked by approximately 8m of black, brecciated, silicified breccias containing sooty pyrite, and this interval is consistently rich in gold. Low levels of anomalous gold continue for at least 30m into the light-gray massive dolomite of the Hamburg, in which the hole was terminated.
BHSE-206C passed through a thick section of limestones - often highly fractured, brecciated, and variably oxidized - that are often anomalous in silver and arsenic in zones of fault breccia and gouge. The degree of brecciation and alteration increases with depth as the limestone passes into a chaotic interval of interbedded sanded dolomite (altered) and fine grained felsic intrusive rock with abundant pyrite, which locally exceeds 10%. The felsic dikes or sills begin at approximately 95m depth. The intrusive unit is light gray to green, fine-grained and has apparent granitic composition, termed an aplite. The aplite has been propylitically altered, evidenced in part by the presence of chlorite, calcite, and sericite.
Gold and silver are most abundant in the dolomite, particularly where it is highly fractured and brecciated. There is a good correlation between the presence of pyrite, gold, and silver, but the most intense silver mineralization is associated with a zone of iron oxide occurring between 270m and 321m depth. Arsenic is a well-known pathfinder element for Carlin-type gold, but it is also associated with the older silver-lead-zinc CRD mineralization in the Eureka District. Almost the entirety of this drill hole is enriched in arsenic, but local anomalies in elements such as bismuth, molybdenum and tungsten support the interpretation of nearby intrusive activity that may be driving the abundant silver (0.05 - 61.3 ppm), lead (2 - 7,000 ppm), and zinc (9 - >10,000 ppm) in the Graben Zone.
Pyrite increases as the drill hole passes into a light gray to pale green, fine-grained section of altered sediments, which may be affected by contact metamorphism from nearby intrusive rocks. The hole was terminated in an interval with abundant chlorite-sericite-pyrite veining and considerable evidence of faulting (brecciation and fault gouge).
Superimposed mineral systems are common and considered favorable in larger Carlin-type gold districts. The Ruby Hill - Archimedes Mine (i80 Gold Corp.), north of the Eureka Project, is an excellent example where millions of ounces of Carlin-type gold resources are reported to occur as overprinting earlier silver (gold) - lead - zinc mineralization. Similarly, at least three generations of mineralization are reported in the giant Carlin Trend District. The multiple generations of mineralization may have used the same fluid pathways in the rocks; plus, the earlier stage alteration and mineralization may have enhanced the receptiveness of the host rocks to the later Carlin-type fluids. Timberline is ramping up for its 2022 exploration program, which will target the Water Well Zone, the Oswego Target, and the huge IP anomaly that occupies the graben in between.
Sampling Methodology, Chain of Custody, Quality Control and Quality Assurance
Cutting and sampling of core samples was directed by Timberline representatives. Personnel from Timberline or the drilling contractors transported the samples to Timberline's secure Eureka facility, from which the samples were picked up by personnel from ALS USA Inc. (ALS) for sample preparation in Elko, Nevada or Tucson, Arizona. Quality control was monitored by the insertion of numerous blind certified standard reference materials, field duplicates, and blanks into each sample shipment. Drill samples were assayed by ALS for gold by fire assay of a 30-gram charge with an AA or ICP-ES finish (ALS code Au-AA23). The overlimits for gold samples assaying above 10 g/t were determined by a 30-gram fire assay with gravimetric finish. Satisfactory results were achieved for all quality control samples related to the data reported herein. In addition, gold mineralized samples were submitted for multi-element analysis (33 elements) by four-acid digestion and ICP-ES determination (code ME-ICP61).

Prospect Ridge Resources
Investor Insight
Prospect Ridge Resources' compelling investment value proposition stems from the company's robust growth ambitions driven by its highly prospective assets near the renowned Golden Triangle region, and a management team with substantial technical expertise.
Overview
Prospect Ridge (CSE:PRR,OTC:PRRSF,FRA:OED) is a precious metals exploration company focused on key projects in Northern British Columbia near the prolific Golden Triangle. The Golden Triangle in northwest British Columbia has been a hub for mineral exploration and mining endeavors for over 150 years. The company owns 100 percent of both the Knauss Creek property and the Holy Grail property.
The Knauss Creek property resembles the high-grade mineralization found in the historical Dorreen mine. Exploration at Knaus Creek has revealed high-grade mineralization comprising gold, silver, copper, lead and zinc. The Copper Ridge zone, which is in the southern part of the Knauss Creek property, is particularly interesting. In 2023, a total of 241 samples were collected from this area which extended the Copper Ridge mineralized zones over an east-west strike length of 1,550 meters, a north-south strike of 850 meters, and a height difference of 470 meters.
Prospect Ridge Resources has also completed an inaugural drilling program at the Copper Ridge zone to test high-priority targets covering an area of 1,550 metres by 850 metres.
The other property, Holy Grail, has also historically produced high-grade gold and silver from placer mining. Prospecting results at the Holy Grail property showed exceptional promise, uncovering significant discoveries of gold, silver, copper, lead and zinc.
Prospect Ridge benefits from a team of professionals boasting extensive expertise in geology and mining. The company is led by Micheal Iverson, CEO, who has more than three decades of experience in mining exploration. The management team has a proven track record of executing several successful exploration and development projects, including Fortuna Silver Mines and NioGold Mining’s Marban project.
Company Highlights
- Prospect Ridge is a Canada-based exploration and development company with two highly prospective land packages in British Columbia.
- The company’s two key assets are the Knauss Creek property and the Holy Grail property, located near the renowned Golden Triangle region in northwestern British Columbia. The Golden Triangle has historically been known for abundant precious and base metal discoveries, with numerous active mining projects and ongoing resource exploration.
- The flagship Knauss Creek property has revealed high-grade surface samples up to 78.9 g/t gold, 4,740 g/t silver, 29.4 percent copper, 33.33 percent lead and 4.10 percent zinc. The Copper Ridge zone is particularly interesting, where a 1.5-km strike zone containing high-grade gold-silver-copper trends were discovered.
- The company has completed an inaugural drilling program to test the drill-ready target Copper Ridge zone as well as other targets.
- Prospecting results from the Holy Grail property are exceptionally promising. They reveal noteworthy discoveries of gold, silver, copper, lead and zinc.
- Prospect Ridge is led by a proven team of executives with more than 100 years of combined experience leading several successful exploration and development projects, including Fortuna Silver Mines and NioGold Mining’s Marban project (sold to Oban Mining, now Osisko Mining).
Key Projects
Knauss Creek Property
The Knauss Creek property, situated 35 kms north of Terrace, BC, spans 2,944. It has excellent infrastructure access, proximity to Highway 16, numerous logging roads traversing it, and the Canadian National Railway passing through.
The property is home to the historical Dorreen mine. Various showings on the property, including the Jay Veins, Hugin, Kandy and Copper Ridge, contain gold, silver, copper, lead and zinc mineralization. The current focus is on the Copper Ridge zone, a high-grade polymetallic mineralization zone spanning 1,500 meters.
Assays from outcrop samples gathered during the 2023 prospecting season have revealed numerous high-grade gold, silver and copper findings. Highlights from rock outcrop sampling, include:
- Sample W489444 contains 6.70 grams per ton (g/t) gold, 4,610 g/t silver, 2.23 percent copper
- Sample W489424 contains 15.9 g/t gold, 987 g/t silver, 0.29 percent copper, 17.55 percent lead, 6.99 percent zinc
- Sample W501837 contains 0.49 g/t gold, 134 g/t silver and 29.4 percent copper
- Sample W501812 contains 2.14 g/t gold, 264 g/t silver and 10.35 percent copper
Consequently, the Copper Ridge zone has been extended, now measuring an east-west length of 1,550 meters, a north-south strike length of 850 meters, and a vertical difference of 470 meters. Field data suggests the veins follow a north-south orientation and dip towards the east.
The interpretation suggests the zone comprises a network of mineralized veins arranged like a ladder hosted within a dioritic intrusion.
The company has completed an inaugural drilling program to evaluate drill-ready targets like the Copper Ridge zone, the Leon’s Legacy and Dorreen Mine showings.
Holy Grail Property
The Holy Grail property is located 10 km north of Terrace, BC, and forms a horseshoe that encloses the fully owned Knauss Creek property in its southeastern part. It currently spans 70,109 hectares. The property is easily accessible via a highway, multiple serviced roads, logging roads, and ATV trails that cross cut it.
Prospecting results from the Holy Grail property displayed remarkable potential through substantial findings of gold, silver, copper, lead and zinc. Key highlights of the results include:
- Grab sample C362354 returned 28.0 g/t gold, 56.9 g/t silver and 2.03 percent copper on the 4 Shore showing
- Grab sample C362357 returned 13.7 g/t gold, 39.9 g/t silver and 1.33 percent copper on the 4 Shore showing
- Grab sample C363353 returned 0.37 g/t gold, 58.7 g/t silver and 3.43 percent copper on the Maroon Creek showing
- Grab sample C363092 returned 6.7 g/t gold, 21.1 g/t silver, and 0.12 percent lead on the Iceberg showing.

TEM | Yalgoo Update - Further Excellent Iron Results
Key Points
- Additional high-grade magnetite iron intercepted in RC drilling
- Consistent intercepts over >2 km of drilled strike length
- Identical outcropping geology mapped over a 5 km total strike length
- Potential for a large-scale iron ore deposit nearby other world-class processing facilities
Remorse Target
High-grade iron
In addition to the lab results for the first drillhole previously reported 1, the Company is pleased to announce the completion of drilling and that follow-up results in subsequent drillholes confirm the presence of high-grade iron at the Remorse Target. New results include:
WARDH00180 16m @ 32.6% Fe from 93m (pXRF)
WARDH00169 20m @ 32.3% Fe from 120m (pXRF)
and 11m @ 30.8% Fe from 182m (pXRF)
WARDH00166 7m @ 32.8% Fe from 96m (Lab)
WARDH00171 8m @ 30.1% Fe from 130m (pXRF)
* Portable XRF (pxrf) results are not comparable in reliability to authorised laboratory results and should be not relied on for quantitative purposes outside indicative demonstrations of potential order of magnitude of enrichments.
Background
TEM has completed the first phase of RC drilling at the Remorse Target of its flagship Yalgoo Project. In total, 21 RC holes were drilled for 4,005m. Samples have been Boxscanned (pXRF) and submitted to the lab and final assay results are expected in December 2024.
The previously reported iron intercept from the first hole drilled at Remorse was WARDH00160 of 32m @ 30.0% Fe from 96m (including 7m @ 37% Fe) (Lab).
The Remorse Target is part of Tempest's broader Yalgoo Project which spans over 1,000 square kilometres of prospective terrain for base metals, precious metals and iron ore.
Figure 01: Section through iron mineralisation WARDH00180
Figure 02: Section through iron mineralisation WARDH00169 and WARDH00163-165.
All samples collected have been analysed using a Boxscan unit which includes a mounted portable X-ray fluorescence (pXRF). Although not as accurate as laboratory analysis, pXRF data when collected in a quality and consistent manner can also exhibit high accuracy and precision. The pXRF data has been compared with assays received to date (>800 samples) and has an average variance of -4.2% and a median of -4.3%. The results indicate the accuracy is considered acceptable for current exploration reporting purposes (and potentially an overall slight underestimation by pXRF).
Remaining assay results are due in December and are expected to correlate strongly with the pxrf results announced.
As previously advised, the drill program design was focused on the strong base metal geochemical anomaly exhibited at the Remorse Target 2. The planned holes were focused strongly on testing the 'hanging wall' stratigraphy at Remorse and were not initially focused on the newly identified iron layer. However, the program did result in the 4 most northerly drill holes intercepting the main magnetite layer and numerous holes intercepting adjacent magnetite-rich layers.
The widely spaced drilling shows continuity and consistency over more than 2 kilometres and identical iron-rich stratigraphy outcrops can be traced over an extensive 5-kilometre zone correlating with the original Remorse Target footprint.
