IRW-PRESS: Heliostar Metals Ltd .: First Heliostar drill hole at Aquila yields 5.56 g / t Au over 5.75 m within thick, near-surface sections at the Unga project (Alaska)
Vancouver (Kanada), 23. Februar 2021. Heliostar Metals Limited (TSX-V: HSTR,
OTCQX: HSTXF, FRA: RGG) (Heliostar or the Company) is pleased to announce full results from hole AQ20-01 on the Aquila target on the Unga Project, Alaska.
The company reported partial results from this hole in its news release dated November 23, 2020. These full results add a second zone of mineralization which significantly expands the mineralized interval at Aquila. The mineralization is open in both directions at depth and along strike.
Highlights of the drilling
– 4.46 g / t Au over 3.6 m from a depth of 37.55 m and
2.24 g / t Au over 17.37 m from a depth of 46.63 m, inclusive
o 5.56 g / t Au over 5.75 m from a depth of 50.25 m
Note: All numbers are rounded and the thicknesses correspond to the drilling lengths. True width is estimated to be 35-90% of the drill length.
Sam Anderson, VP of Exploration for Heliostar, said: The Aquila target is a new zone and the discovery of such a thick, shallow segment of gold mineralization in the first hole opens a whole new and exciting area of exploration at Unga. Aquila, which is located six kilometers southwest of the SH-1 resource, runs along the same vein and has exposed gold mineralization for 850 meters, is one of the significant potential exploration targets identified and drilled in 2020. Due to the temperate climate on the project, the company will resume drilling in late March and a back-out drilling from this discovery hole will be a priority for the 2021 program.
The Aquila target is a series of exposed epithermal quartz veins extending along the Shumigan vein section. Heliostar has targeted the area as historical work has identified multiple areas of exposed mineralization while limited drilling at large distances has inconsistent with surface results.
In the early 1980s, a program conducted by UNC Teton Exploration Drilling Inc. discovered the area and defined multiple veins in a 1,000 by 500 meter area within an interpreted zone of structural dilatation. Trenching along the primary vein zone returned a best result of 11.48 grams of gold and 53.47 grams of silver per ton over 3.66 meters (the Qualified Person was unable to independently verify and verify the historical assay results presented above Heliostar wells are used to determine the grades and thicknesses of the ore targets at Aquila).
Historic drilling has been completed at nine locations across the Aquila target area, with poor core recovery hampering the program. No significant further exploration has been conducted since the early 1980s until the Heliostar drill program in 2020.
Heliostar began drilling approximately at the location of a historic well that had poor core recovery in the targeted vein zone, with hole AQ20-01 and subsequent holes AQ20-02 through -05 testing the vein both along strike and at depth to have. These holes have significantly improved core recovery on the primary Amethyst vein and defined a second vein orientation, the Ankle Creek Vein, which is an extremely favorable development and offers significant room for expansion along strike and at depth.
The veins at Aquila consist of quartz, calcite and amethyst and often contain brecciated rock fragments from veins and masonry. Quartz often has cockscomb and coloform epithermal structures and the veins have experienced multiple impulses of brecciation and vein formation. Mineralization is associated with small amounts of finely disseminated sphalerite and galena in the vein and occasional pyrite along the vein margins.

About Heliostar Metals Ltd.
Heliostar is a well-funded junior exploration and development company with a portfolio of high grade gold projects in Alaska and Mexico. The company’s flagship project is the 100% controlled Unga Gold Project in the Unga and Popof Islands of Alaska. The project is host to an epithermal intermediate sulphidation gold deposit located on the district-scale 240 km2 concession area spanning both islands. Other targets on the property include porphyry, epithermal veins with high and intermediate sulphidation. Priority targets on Unga Island include: SH-1 and Aquila, both on the Shumagin Trend, the former Apollo-Sitka Mine, which was Alaska’s first underground gold mine, and the Zachary Bay gold-copper porphyry prospect. Gold mineralization in the Centennial Zone is located on neighboring Popof Island, just four kilometers from the infrastructure and services at Sand Point.
In Mexico, the company owns all interests in three early stage epithermal projects in Sonora that are highly prospective for gold and silver. Cumaro is part of the El Picacho district, while the Oso Negro and La Lola projects are also prospective for epithermal gold-silver mineralization.
Quality assurance / quality control
The drill core samples were sent to the ALS Limited facility in Fairbanks, Alaska for sample preparation and to the ALS laboratory in North Vancouver for analysis. ALS facilities in Fairbanks and North Vancouver are ISO / IEC 17025 certified. Silver and base metals were analyzed using a four acid digestion followed by ICP, and gold was analyzed in a 30 gram weight by fire assay and subsequent atomic absorption spectroscopy (AA). Gold contents above the detection limit were analyzed in a 30 gram sample weight using a fire test and a subsequent gravitation method.
Control samples, which included certified reference samples, duplicates, and blanks, were systematically added to the sample stream and analyzed as part of the company’s quality assurance / quality control protocol.
The publication of technical or scientific information in this news release has been reviewed and approved by Stewart Harris, P.Geo., Exploration manager for the company. Mr. Harris is a qualified person as defined by National Instrument 43-101.
