American Creek Completes High-Resolution Magnetic and LIDAR Surveys at Past Producing Dunwell Mine Property in Golden Triangle of BC

Cardston, Alberta--(Newsfile Corp. - September 11, 2020) - American Creek Resources Ltd. (TSXV: AMK) ("the Corporation") is pleased to report that it has now completed a 450 line km high-resolution magnetic survey in combination with a LIDAR survey at the company's 100% owned Dunwell Mine gold and silver property located in the Golden Triangle of British Columbia.

Genesis Aviation Inc. was chosen to complete the High-Resolution Gradient Magnetometer survey in conjunction with a Three-Dimensional LIDAR survey over the property. This type of magnetic survey is flown by a low altitude helicopter and offers Measured Horizontal and Vertical Gradient data. This makes a significant difference to the magnetic inversion that provides a model at depth. The survey, which was conducted over the whole property, will allow the past, present and future geological and geophysical programs to be correlated with a much higher degree of accuracy than otherwise possible.

Darren Blaney, CEO and President stated: "We look forward to seeing the results of the recently completed magnetic and Lidar surveys as that new data, combined with our fall 2019 IP data, will greatly expand our understanding of the underground geology and enhance drill placement and targeting. We will also now be able to develop strong correlations between known mineralized zones and future untested targets thus potentially improving our hit ratio as we target these high-grade vein systems with the drill.

We have always thought that the numerous high-grade gold and silver showings associated with the Portland Canal Fissure Zone, that extends through the property for several kilometers down the valley, are related in some meaningful way and are likely part of the same geological event. We will soon be in position to begin proving this with the commencement of the Dunwell Phase II drill program planned for this fall."

The Dunwell Mine is a high-grade past producing polymetallic mine located just 8 kilometers by road from the shipping town of Stewart, BC. The mine itself is one of dozens of high-grade gold / silver / lead / zinc occurrences that are primarily associated with the Portland Canal Fissure zone that extends for several kilometers through the property. The Dunwell Mine project boasts exceptional logistics and a rich mining history with potential for future development. It is located within the Bear River valley which was one of the first areas prospected in the Stewart camp because of its combination of rich veins and easy access due to the low elevation and close proximity to town.

Because of the property's low elevation and heavy rainfall, it is completely covered with a heavy canopy of vegetation with exposed bedrock limited to gullies and stream beds. Notwithstanding this limited surface outcrop, there are over two dozen known high-grade showings on the property. As no modern exploration techniques or technologies had been employed on the Dunwell property prior to American Creek's acquisition, careful consideration was given as to the best options and techniques that could lead to discovery. This analysis resulted in a decision to proceed with an extensive Induced Polarization (IP) survey in the fall of 2019 and, to further define targets, this just completed detailed Magnetic survey in 2020.

Alpha IP was chosen over a conventional IP survey because of its cutting-edge technology in detecting detailed high chargeability / low resistance anomalies in the ground. Specifically, the Alpha IP survey has far greater resolution and depth than standard IP's and can provide the data in a 3D view. These are critical factors as the Dunwell Mine property contains numerous high-grade veins that are potentially more readily detected using a high-resolution survey.

Simcoe Geoscience, who performed the survey, was chosen because of their exceptional experience in this field and the in-depth interpretation they provide. Once the data provided by Genesis is processed, Simcoe will also be using their expertise to integrate the new 3D Magnetic Survey results with the existing IP results, the 2019 maiden drill program results, and all historic data in order to fine tune drill targets. Simcoe's same Alpha IP system continues to achieve success locating high-grade veins at Ascot's neighboring Silbak-Premier Mine (9km away).

The exploration objectives of the Alpha IP survey were to detect the source of potential high‐grade Au, Ag, Pb, Zn, Cu in quartz and detect quartz breccia vein systems hosted within thin bedded argillite, siltstone and greywacke of the Middle Jurassic Salmon River Formation (Hazelton Group). The Alpha IP system was used to provide the following benefits:

  • Detect and delineate zones and structures related to the emplacement of sulphide mineralization to depths of up to 400 meters with chargeability and resistivity.
  • Mapping the resistivity and chargeability features related to mineralization, alteration, faults and lithologies.

Results from the fall 2019 survey resulted in thirty-seven anomalous zones being identified and interpreted as significant targets for follow up from surface to ~300m+ depth. Out of thirty-seven anomalous zones, fifteen are considered first priority, sixteen second and six are third priority targets. The anomalous zones consist of strong to moderate chargeability related to associated conductive to resistive zones. These targets have a strong correlation with the Portland Canal Fissure Zone with the strongest targets running along the Dunwell Creek / Portland Canal Faults, the secondary targets running down each side of the primary target, and the tertiary targets running along the western edge of the fissure zone.

Property Description and History

The Dunwell property is located just 7 km east of the Silbak Premier Mine (Ascot Resources), 11 km west of the Red Mountain deposit (Ascot - formally IDM), and only 9 km north of the past producing Porter Idaho silver mine (Strikepoint Gold). Through a series of strategic acquisitions American Creek was able to purchase the past-producing Dunwell Mine as well as several adjoining very prospective properties, combining them into one large land package that encompasses the most promising gold and silver mineral occurrences and historic workings within the Bear River valley. The amalgamated property spans 2,222 hectares covering the majority of the Portland Canal Fissure Zone, an area first prospected in the late 1800's and hosting some of the earliest producing gold and silver mines in the Stewart area.

The Portland Canal Fissure Zone is the most significant geological feature in the Bear River valley. This zone of faulting and shearing trends north, dips steeply west, and hosts a vein system that extends southward for 6.5 kilometres from the Victoria/Dandy occurrence (on Dunwell) in the north, through the Dunwell mine itself, across Glacier Creek to the Ben Bolt occurrence (on Dunwell) in the south. With the recent acquisition of the Glacier Creek Crown Grants (south of Glacier Creek), American Creek now controls 5km of the 6.5km fissure zone which contains numerous high-grade polymetallic mineral occurrences including two past producing mines (Dunwell and Portland Canal).

The Dunwell project is located 8km northeast of Stewart and is road accessible with the Dunwell Mine adit itself located only 2km from Highway 37A and a major power line (both running through the property). Stewart hosts two deep sea ports including ore loading and shipping facilities. Unlike the majority of mineral properties located in the Golden Triangle near Stewart, the Dunwell Mine is located in low mountainous terrain (800m and lower elevation) with relatively moderate relief. These features allow for potential year-round work which typically isn't the case for exploration programs conducted in the Stewart region where projects are typically at higher altitude, are accessible only by helicopter, and lack critical infrastructure such as roads and power. The Dunwell Mine project may very well have the best logistics of any project within the Golden Triangle.

According to historic records, the Dunwell Mine is the most significant mineral occurrence within the Portland Canal Fissure Zone. Production at the Dunwell occurred between 1926 and 1941. From historic production reports, it appears that a total of 45,657 tonnes averaging 6.63 g/t gold, 223.91 g/t silver, 1.83% lead, 2.43% zinc and 0.056% copper were produced.

American Creek's Phase I maiden drill program on the Dunwell (which took place within the vicinity of the Dunwell Mine in the fall of 2019) produced many high-grade intercepts including:

  • 19.4 g/t AuEq over 3.6m
  • 20.3 g/t AuEq over 2.69m
  • 38.1 g/t AuEq over 0.5m
  • 28.5 g/t AuEq over 0.45m
  • 24.4 g/t AuEq over 0.5m
  • 18.4 g/t AuEq over 1.5m
  • 19.5 g/t AuEq over 1.2m
  • 13.3 g/t AuEq over 1.4m
  • 16.2 g.t AuEq over 0.8m
  • 15.1 g/t AuEq over 0.6m
  • 28.2 g/t AuEq over 0.43m
  • 18.5 g/t AuEq over 0.7m
  • 10.7 g/t AuEq over 1m
  • 15.1 g/t AuEq over 0.6m

*AuEq uses $1,500 gold, $18 silver, $0.88 lead, $0.95 Zinc and $2.5 copper

In addition to the Dunwell mine itself, the property package also contains over two dozen other high-grade gold and silver occurrences and historic small-scale gold/silver high-grading operations along a north/south trend that correlates to the fissure zone and major faulting. Some examples of the nine areas on the Dunwell property that produced ore historically are:

  • Ben Ali:                4,500 tons at 21.6 g/t gold
  • Lakeview             60 tons at 4.7 g/t gold, 2,734 g/t silver, and 11.5% lead
  • Victoria                11 tons at 20.15 g/t gold, 775 g/t silver, 25% lead
  • Tyee                      8.2 tons at 124.4 g/t gold and 4,478.8 g/t silver
  • George E             12 tons at 13 g/t gold and 3,250 g/t silver, 23.3% lead

Each of these areas were producing during the 1930's when exploration techniques and technology was very primitive. They were basically high-grading operations focused on vein systems that were exposed on surface.

The High-Resolution Gradient Magnetometer survey combined with the 3D Alpha IP survey represent the cutting edge in geophysical technology today and are designed to aid with understanding potential correlations between the multiple high-grade surface showings.

The Dunwell Phase II drill program is expected to commence in the near future once the data and interpretation from the geophysical survey is integrated with the IP data, last year's drilling data, and all historical data.
