Heliostar Expands Aquila Discovery to 475 Metres with

Multiple New Intercepts from Surface at Unga, Alaska

Vancouver, Canada, September 20th, 2021 – Heliostar Metals Limited (TSX.V: HSTR, OTCQX: HSTXF, FRA: RGG)

("Heliostar" or the "Company") is pleased to announce results from the six additional Reverse Circulation (RC)

holes completed at the Aquila vein target, part of the large scale Unga district in Alaska.

These results position Aquila as a third centre of mineralization at the Unga project. The target is connected by

road to the SH -1 Resource and the former Apollo Mine, providing convenient access for further lower cost

exploration and potential mining options.

Highlights

• Intercepts over 475 metres (m) of length that is open to the northeast and at depth

• Geological evidence is that this shallow mineralization is only the top of the system

• High grade intercepts within a broader halo of lower grade gold mineralization from surface

AQRC21-12: 1.77 g/t gold over 18.28 m from 4.57 metres (m), including;

▪ 3.44 g/t gold over 7.62 m from 10.67m

AQRC21-13: 0.55 g/t gold over 41.15 m from 1.52m, including;

▪ 5.95 g/t gold over 1.52 m from 4.57m

All numbers are rounded and widths represent drilled lengths. True thickness is estimated at 80-95%

Heliostar CEO, Charles Funk, commented: “The 2021 program continues to deliver, showing the SH-1 Resource is

just one of many high grade targets within the Unga district. These results build on those from earlier in

September at Aquila and define a new zone with intercepts from surface that ar e wide open for expansion .

Systematic exploration is proving very successful to unlock the Unga District and more assay results are pending

from this year’s program , including from the SH-1 Resource and Apollo targets. Planning has commenced for

drilling at Centennial in November and December due to the ability to drill year-round on parts of the project.”

Aquila Target

The Aquila Target comprises outcropping epithermal quartz veins within the Shumigan vein corridor located 5

kilometres southwest of the SH-1 Resource (384,000 inferred ounces of gold at 13.8 g/t gold). It is one of the four

highest priority targets on the Unga project (Figure 1) amongst 38 areas of either mineralization, mineralized

outcroppings, historical resources and/or anomalies.

has not been able to independently verify the resource at Centennial and Heliostar plans on conducting an exploration

program at Centennial to establish the grades and widths of mineralization at these prospects. The SH-1 resource is current

and is referenced in the “Amended and Restated N.I. 43 -101 Technical Report & Resource Estimate for the SH -1 Gold and

Silver Deposit” by W.T. Ellis, dated November 24, 2020, and which can be found at www.sedar.com.

In 2021, thirteen RC holes were completed at Aquila; all intersected the Amethyst Vein (Figure 2) which now has

a drill defined minimu m strike length of 475 metres. Two separate zones along the vein contain higher -grade

gold mineralization and both remain open for expansion with follow-up diamond drilling.

New results from drill holes AQRC21-12 and 13 are step-out holes and were drilled 80 metres and 120 metres to

the to the northeast of the discovery hole AQ20-01 (4.46 g/t gold over 3.6 m and 2.24 g/t gold over 17.37 m). In

total, five holes define a zone of continuous mineralization that is at least 1 20 metres long and tha t remains

undrilled and open to the northeast and at depth. Surface samples returned up to 30.8 g/t gold to the northeast

that are yet to be drill tested.

Heliostar performed all 2021 drilling at Aquila with RC and the deepest drill intercept to date is o nly 70 metres

below surface. Mineralization is open at depth with the expectation that there is a significant window for

mineralization down-dip.

The company interprets that the current drilling as being at only at the top of the mineralized system. The

geological evidence of a high gold to silver ratio, high precious metals to base metal ratio, relative elevation of

Aquila to SH-1 and Apollo and specific quartz textures observed within the veins indicates a shallow level within

the system. At Apollo, mineralization was defined over 500 metres vertically and drilling at SH-1 has defined high

grade gold over 250 metres vertically that remains open at depth.

Heliostar’s geologists infer that the Aquila target has excellent potential for further expansion.

It is also important to note that gold mineralization becomes thicker to the northeast, around drill holes AQRC21-

12 and 13, indicating that the gold mineralizing system may be becoming more robust in this direction. This area

is a major intersection of the regionally significant northeast str iking Shumagin Vein Corridor and several east -

west striking veins. Vein intersections often form the basis for gold rich shoots within the veins which is looking

likely in this zone at Aquila.

Quality Assurance / Quality Control

Drill samples were shipped to ALS Limited in Whitehorse, Yukon for sample preparation and for analysis at the

ALS laboratory in North Vancouver. The ALS Whitehorse a nd North Vancouver facilities are ISO/IEC 17025

certified. Silver and base metals were analyzed using a four-acid digestion with an ICP finish and gold was assayed

by 30-and 50 gram fire assay with atomic absorption (“AA”) spectroscopy finish and overlimits were analyzed by

50g fire assay with gravimetric finish.

Control samples comprising certified reference samples, duplicates and blank samples were systematically

inserted into the sample stream and analyzed as part of the Company’s quality assurance / q uality control

protocol.

The company’s flagship asset is the 100% controlled Unga Gold Project on Unga and Popof Islands in Alaska. The

project hosts an intermediate sulfidation epithermal gold deposit, located within the district-scale property that

encompasses 240 km2 across the two islands. Additional targets on the property include porphyry copper-gold

targets, high sulphidation targets and intermediate sulphidation epithermal veins.

On Unga Island, priority targets include: the 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 porphyry gold-copper prospect.

Gold mineralization at the Centennial Zone is located on neighbouring Popof Island within four kilo metres of

infrastructure and services at Sand Point.

In Mexico, the company owns 100% of three early-stage epithermal projects in Sonora that are highly prospective

for gold and silver. Cumaro forms part of the El Picacho district, while the Oso Negro and La Lola projects are

early-stage projects considered prospective for epithermal gold-silver mineralization.
