Blue Star Gold Exploration Update – Newly Identified Mikigon Prospect – Up to 47.1 g/t Gold Sampled at Surface

8 August 2023

Blue Star Gold Corp.


Blue Star Gold Corp. announces initial results from its 2023 exploration program. The program includes a multi-prong exploration effort across the Company’s Ulu Gold Project including ground-based geophysical surveys, ground-truthing pipeline targets, mapping and lithogeochemical sampling, and prospecting. The program has been focused to identify and advance targets throughout Blue Star’s highly prospective landholdings to be drill ready for a 2024 discovery program.


  • NEW discovery “Mikigon Prospect” is a sediment hosted mineralised structure traced for 550 metres into overburden (open), highlighted by samples returning 47.1 grams per tonne (“g/t”) gold, 29.6 g/t gold, and 22.7 g/t gold;
  • Pipeline target Penthouse confirmed to be a precious metals rich base metal prospect, traced on strike for 400 metres (open), highlighted by samples returning 26.9 g/t gold, 184 g/t silver, 5.73% copper, 7.12% zinc; and 1.54 g/t gold, 8.59 g/t silver, 0.345% copper with 6,850 g/t cobalt;
  • Pipeline target Rhonda confirmed to be a precious metals rich base metal prospect, at a flexure in a mafic volcanic over sediment contact zone, highlighted by samples returning 6.04 g/t gold, 69.9 g/t silver, 0.587% copper, and 12.4% zinc;
  • Bamako showing (now the Auma Prospect) staked as part of the Roma Project, historical work indicates a 1.5 km long AEM conductor associated with a magnetic anomaly coincident with quartz-pyrrhotite veining; multi-ounce gold grab samples returned with a historical drill intercept of 15.3 g/t gold over 2.6 metres in a ‘gopher’ drill hole.

Blue Star’s CEO, Grant Ewing, commented, “The discovery of the Mikigon prospect highlights the strong potential for significant new mineralised zones at the Company’s projects. This new prospect along with several other high potential targets will be ready for drill testing in future programs. The focus continues to be on evaluating and prioritizing the large pipeline of targets for gold potential, but it is also evident that Blue Star’s vast landholdings have excellent potential for the discovery of critical mineral deposits, including copper, zinc and cobalt.”

Blue Star’s VP Exploration, Darren Lindsay, commented, “Having the support to undertake a significant mapping program has allowed the exploration team to better understand the geological framework and mineralisation settings leading to field-based new target identification this season. This work will assist in the prioritisation of our pipeline targets and eventually to additional discoveries at the end of a drill bit.”

Discussion of Field Results

Mapping has focussed on the 5 km long Ulu fold between the Flood Zone gold deposit and the NFN deposit, and the North and South Penthouse areas. Mapping is being undertaken at scales of 1:5000 and 1:2500, and pXRF scanning of rock chips is used to determine areas for lithogeochemical sampling to better define and understand the stratigraphic package and differentiate between more prospective lithological units. These map areas host many of the key pipeline prospects. Prospectors are focused on both areas with no previous sampling, and also on confirming and expanding pipeline targets.

The Mikigon Prospect was identified during mapping of the sediments surrounding the Ulu Fold in an area of no previously known sampling. This is the first known substantial sediment hosted mineralised zone in the Ulu Gold Project. It is located approximately 3.5 km NNE of the Flood Zone gold deposit and 1.8 km SE of the NFN deposit. A total of 33 samples, over a strike length of 550 metres from a mineralised trend 1 to 4 metres wide on surface, have been collected to date. The prospect is highlighted by samples returning 47.1 g/t, 29.6 g/t and 22.7 g/t gold and has a mean gold value of 3.75 g/t in a range of detection limit to 47.1 g/t gold.

The Rhonda Prospect was evaluated to confirm location of historical sampling and better define the north-south contact/structural trend. The core of the prospect is approximately 30 metres long within a 450-metre section of the structure defined by historical soil samples. The prospect is located approximately 1.3 km SW of the Flood Zone gold deposit and 900 metres from the camp road. A total of 15 grab samples were collected from outcrop, subcrop and frost heave returning a mean gold value of 1.97 g/t, a mean silver value of 29.2 g/t and a mean zinc value of 2.8% in a range of detection limit to 6.04 g/t gold, 69.9 g/t silver, and 12.4% zinc.

The historical Penthouse showing is hosted within a sedimentary rock package located below a basalt contact and is traceable for at least 400 metres. The discontinuous massive sulphide horizon ranges from 0.15 to 0.75 metres wide in the main zone with potential for multiple target horizons in the rock package. Similar alteration has been observed below the main level, and gold bearing quartz veins occur at an oblique angle. Results from five samples received to date are tabulated below with a grab sample from a massive sulphide zone in outcrop returning a highlight grade of 26.9 g/t gold, 184 g/t silver, 5.73% copper, and 7.12% zinc (see Plate 1).

The 164-hectare Auma Prospect was recently staked as part of the Roma Project. Historical work includes airborne electromagnetics (AEM), ground based magnetics and horizontal loop EM (HLEM), mapping, prospecting and six ‘gopher’ drill holes. Reported results of the work include a 1.5 km long AEM conductor, a 700 metre long coincident HLEM conductor and magnetic high; numerous anomalous grab samples of quartz-pyrrhotite veins and three distinct map units. Grab samples reported from previous exploration companies range to 54.4 g/t gold (BHP 1991), 101.0 g/t gold (Strongbow/Allyn Resources 2005) and 183.79 g/t gold (Oz Minerals 2008) (pers. comm. T.Toole, 2023). Drilling results reported by Zaremba and Takenaka in 1995 include drill hole 95HBD-02 which intercepted 2.60 metres of 15.3 g/t gold. Blue Star has not yet undertaken sufficient work to verify and validate the historical data.

See Figure 1 for a location map of the zones discussed above. Table 1 lists select sample results with full data available on the Company’s website in the near future.

2023 Exploration Program Summary

Blue Star is continuing to build and assess its extensive target pipeline with a focus on expanding the current resource areas and prioritising several new targets. The technical team’s improved understanding of the geological controls on mineralization following the last two successful field programs has led to advancing target areas to drill ready.

A geophysical program conducted by Aurora Geosciences Inc. of Yellowknife, NT entailed ground-based surveys designed to confirm and refine drill targets in the +1,200-metre-long Gnu Zone target area, and to visualize potential depth extensions to the Flood Zone. These will be reported once final interpretations are available.

Mapping, prospecting, and geophysical survey data processing is on-going and will be compiled and reported as results become available. Structural and stratigraphic studies will be compiled and reported once the data has been received and interpretation is completed.

Several improvements have been made at the Ulu exploration camp, including remediation work to clean up legacy waste, resulting in a significant increase in efficiencies of the operation.

Blue Star’s Projects

The Company’s properties are located approximately 525 km NNE of Yellowknife, NT in the Kitikmeot region of western Nunavut. Kugluktuk is approximately 210 km to the NW. The total area of Blue Star’s projects cover over 45 km of the highly prospective and underexplored High Lake Greenstone Belt.

The Ulu Gold Project, comprised of the Ulu Mining Lease and the contiguous Hood River Property together encompass greater than 12,000 hectares of high potential exploration ground. The recent acquisition of the prospective and underexplored Roma Project increased the Company’s landholdings by more than 14,000 hectares in the High Lake Greenstone Belt.

The Ulu Mining Lease hosts the advanced stage Flood Zone gold deposit, where a significant high-grade gold resource has been outlined. Several additional gold prospects (including, but not limited to, Zebra, Contact, Central, Axis, and Gnu) are spatially related to the axis of the ~5 km long Ulu Fold, which extends from the Ulu lease onto the northern part of the Hood River Property and culminates at the North Fold Nose Zone. The recent expansion of the Hood River concession added several new target zones south of the Flood Zone gold deposit. The eastern side of the Hood River Property is contiguous to the Ulu Mining Lease, and hosts over twenty known gold showings. The Hood River prospects have the same deformation history (including tight folding) as well as similar mineralisation styles (acicular arsenopyrite and polymetallic quartz veins) and stratigraphic sequences as the Flood Zone. One of the most prospective target areas on the eastern Hood River Property is the 4 km long Crown-Pro trend which has seen only limited drilling.

The Roma Project lies in the northern section of the High Lake Greenstone Belt. The project covers high grade gold showings discovered by previous explorers, notably BHP Minerals from 1988 to 1994. Multiple significant gold showings are present within a 6.5 km x 2.4 km area on the historic Roma claim block. The original showing is a 0.30 to 3.0 m wide quartz vein exposed in outcrop and boulders for 2 km. In 1991, BHP drilled ten shallow holes totaling 465 metres to test 1.72 km of the strike of the vein. All drill holes intersected quartz veins from 15 m to 37 m vertically below surface. Visible gold was noted in three of the drillholes and the best results were 12.38 g/t gold over 2.31 m (including 64.0 g/t gold over 0.37 m) from DDH MD-01, and 8.69 g/t gold over 1.87 m from MD-03. No drilling was conducted downdip of the high-grade intersection in DDH MD-01 and no step out drilling to the north from this intercept was conducted. No follow up drilling is known to have been completed on this property since BHP’s initial drill program in the 1990’s. The company has not verified the historical results from the Roma Project and has presented information obtained from two assessment reports submitted by BHP Minerals: G. McMaster (1995), Roma 3, 4, 5 and 6 claims 1995 geological and geochemical report; and L. Anonby and W. Jopson (1992), geological, geochemical, geophysical and drilling report on the Roma 1 and 2 claims.

The Auma Prospect is located on the western margin of the High Lake Greenstone Belt and covers high grade gold showings discovered by previous explorers, notably BHP Minerals from 1990 to 1995, Strongbow Resources from 2004 to 2006 and Oz Minerals from 2007-2008. In 1995 BHP undertook drilling of six ‘gopher’ holes in two zones; results from Zone 1 included 2.6 m of 15.3 g/t gold (AR083564 Zaremba,C. and Takenaka,C. 1995 Geological, Geochemical and Geophysical Report on the Bamakao6 and 9 Claims, NTS 76M3. BHP Minerals Canada Ltd.). In 2006 Strongbow mapped the area in detail and noted numerous unsampled veins; sampling also discovered Zone 3 with a grab sample value of 39.3 g/t gold (AR084947 Strongbow Exploration/Allyn Resources 2004-2005 (Bryan 2005)); in 2008 Oz Minerals evaluated the area with a result of 183.79 g/t gold from Zone 3 (pers.comm., T.Toole, 2023).

The site of the future deep-water port at Grays Bay is 40 – 100 km to the north of the properties, and the proposed route corridor for the all-weather Grays Bay road passes near the Roma and Ulu Gold Projects.
