Blue Star Gold Drills 12.5 g/t over 7 Metres at the Flood Zone and 52.7 g/t over 2 Metres at the Gnu Zone on Its Ulu Gold Property

 

 

 

 

 

Blue Star Gold Corp. (TSX-V: BAU) (FSE: 5WP) announces additional assay results from the recently completed 7,624 metre diamond drilling program at its Ulu and Hood River properties. The 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.

 

Highlights:

 

  • 7,624 metres drilled in thirty-eight diamond drill holes during the program
    • Ten holes were drilled at Ulu and Gnu deposits to expand known resources and confirm the geologic model, and twenty-eight holes were drilled to test exploration targets on both the Ulu and Hood River properties, including fourteen in the North Fold Nose (NFN) zone
    • Assay results for an additional 2 Flood zone, 1 Gnu zone and 3 Hood River property drill holes are announced today
  • Highlight gold assay results for the Flood zone (BS2020ULU-006):

    • (see news release dated Sept. 30, 2020 for assay results from the initial holes released, including 3 Flood zone and twelve NFN zone holes)

 

Ulu and Hood River Properties

 

The Ulu lease and the contiguous Hood River property together encompass approximately 9,000 ha of highly prospective exploration ground. The Ulu lease hosts the advanced stage Flood and Gnu gold deposits, where a significant high-grade gold resource has been outlined. A series of gold occurrences occur on-strike and north of the Flood gold zone and are thought to be related to the ~5 km long Ulu regional fold that extends from the Ulu lease on to the north Hood River property culminating at the NFN zone. This structure, called the Robb trend, extends from the Flood and Gnu gold zones along the Ulu fold to the north and hosts at least five gold zones in addition to the Flood and Gnu zones (NFN, INT, Bizen, Apex and Contact zones) (see Figure 1, page 5). The Hood River property is contiguous to the Ulu lease to the north, east and south, and hosts over twenty known gold showings (see Figure 2, page 6). Many of the high-priority target areas outside of the Flood zone have only been tested with relatively shallow drilling, and the potential throughout the properties to host new discoveries at depth is considered high. Refer to the Company’s website to view a 3-D model of the Flood and Gnu deposits.

 

Next Steps, Upcoming Milestones

 

  • The balance of the assay results from the program are expected to be announced over the coming weeks through into early December
  • Plans underway to update the Flood and Gnu zone resource model following assessment of all the drill program data. The Flood and Gnu zones have excellent resource expansion potential and it is anticipated that the first resource estimate for the NFN zone will be completed
  • Detailed targeting and planning for an aggressive 2021 exploration program will be initiated over the coming months
  • The 2021 exploration focus will be: expansion of the high-grade resource base (Flood and Gnu zones), targeting proximal to the resource zones where excellent potential exists for new discovery, and regional targeting over the extensive and highly prospective Ulu and Hood River properties, where numerous high-grade gold showings exist

 

2020 Exploration Program Summary

 

The program entailed 7,624 metres of diamond drilling in thirty-eight diamond drill holes on the Ulu and Hood River properties. The Flood zone holes were drilled to; provide additional geologic information and confirm certain aspects of the geologic model of the deposit, to improve drill hole density and allow for possible upgrading of the resource category, and to expand the resource base. The Gnu zone hole was drilled to further understand the host structure. The 3 Hood River property holes tested 2 early stage targets (INT and Bizen zones) on the highly prospective property.

 

Assays results from the balance of the 2020 exploration program will be announced over the coming weeks as they become available.

QA/QC Program for the 2020 Exploration Work

 

All drill core was logged and sampled in secure core processing structures located at the Ulu or Hood River camps. Drill core samples were collected by either cutting the core in half using diamond saws or by splitting the core in half using hydraulic core splitters. In addition to the QA/QC protocols of ALS Global, the Company maintains its own program of inserting Standard Reference material in the form of standards and blanks into the sampling stream, prior to being shipped to ALS’s preparation facility in Yellowknife.

 

History and Geology of the Ulu and Hood River Gold Properties

 

The 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 Ulu property consists of a renewable 21-year mining lease and covers an area of approximately 947 ha. The lease hosts an advanced gold project that between 1989 and 2012 saw significant exploration and development by BHP Minerals and Echo Bay Mines, among others. The past work includes approximately 1.7 km of underground development and approximately 405 diamond drill holes that produced 97,820 m of core (Ulu and Hood River). The Flood zone contains the bulk of the Ulu gold resource and is open on-strike and at depth. Overall resources of 2.50 million tonnes grading 7.53 g/t Au for 605,000 gold ounces (measured & indicated category) and 1.26 million tonnes grading 5.57 g/t Au for 226,000 gold ounces (inferred category) have been estimated for the Flood and Gnu zones (refer to “Technical Report on the Ulu Gold Property, Nunavut, Canada” dated July 10, 2015). The deepest intersection of mineable width at the Flood zone is 14.9 g/t Au over 7.7 m in BHP’s drill hole 90VD-75 at 610 m below surface. Metallurgical testing on the Flood zone gold mineralization has shown that gold is recoverable in amounts greater than 90% by gravity, flotation and cyanidation.

 

The Hood River property is contiguous to the Ulu lease to the north, east and south. The property is held through a renewable, 20 year Mineral Exploration Agreement with Nunavut Tunngavik Incorporated. The highly prospective property encompasses 8,015 ha. At least 22 known gold showings have been identified on the property. The exploration target for the property is shear-hosted gold mineralization similar to the Flood zone on the adjacent Ulu lease.

 

A series of gold occurrences occur on-strike and north of the Flood gold zone and are thought to be related to the ~5 km long Ulu regional fold that extends from the Ulu lease onto the north Hood River property culminating at the NFN zone. This structure, called the Robb trend, extends from the Flood and Gnu gold zones along the Ulu fold to the north and hosts at least five gold zones in addition to the Flood and Gnu zones (NFN, INT, Bizen, Apex and Contact zones).

 

Gossanous auriferous rocks hosted within mafic volcanic units at or close to the contact with meta-greywacke rocks occur along the Robb trend. The gold mineralization is commonly enveloped by an alteration halo of biotite-actinolite-quartz. The mineralized zones are believed to be the result of brittle-ductile failure caused by regional stresses during different deformation stages. Along sedimentary-volcanic contacts, regional folding causing shearing, due to lithological competency contrasts, resulted in minor dilatancy. These dilatational zones were in-filled with the gold-arsenic-rich hydrothermal fluids. Mineralization shows pinch and swell style.

 

Several high-grade gold occurrences also occur on the east Hood River property, including the Crown and Penthouse zones, where gold trends with similarities to the Robb trend may exist. In addition, many unnamed gold occurrences exist on the two properties, where further prospecting is required to advance the showings to target zones. The large number of high-grade gold showings that occur throughout the properties provide for excellent resource expansion potential at multiple targets.

 

Supplementing the high-grade gold resources, the Ulu project includes a substantial inventory of capital equipment, a Weatherhaven camp with shop and a 1,200 m long airstrip. The site of the future deep-water port at Grays Bay is 100 km to the north of the properties, and the proposed route corridor for the all-weather Grays Bay road passes in close proximity to the Ulu and Hood River projects.

Notes to the Resource Estimate

 

  1. Mineral resources which are not mineral reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.
  2. Confidence in the estimate of Inferred Mineral Resources is insufficient to allow the meaningful application of technical and economic parameters. There is no guarantee that all or any part of a mineral resource can or will be converted into a mineral reserve.
  3. The mineral resources in this estimate were calculated using the Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”), CIM Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the CIM Standing Committee on Reserve Definitions and adopted by CIM Council.
  4. The reliability and accuracy of downhole surveys in 188 of 313 drill holes in the resource area are in question due to their lack of proper measurements. For these holes, the QPs have imposed an average demonstrated predictability of drill hole deflection that are present in holes on the property that do have proper downhole measurements. In the opinion of the QPs, this is a more reasonable assumption than assuming straight line drill holes.
  5. The following parameters were used to derive the cut-off: CA$100/t mining costs, CA$25/t processing costs and CA$10/t G&A; transporting gravity and flotation concentrate to the Lupin to produce dore with a CA$25/t transport cost; CA$1500/oz gold price; process recoveries of 90%, smelter payables of Au at 96% and refining charges of Au CA$12/oz.
  6. The Company filed its technical report, titled “Technical Report on the Ulu Gold Property, Nunavut, Canada” dated July 10, 2015 from which the table of resources was taken. Gary Giroux, P.Eng. of Giroux Consulting Inc., Bob Singh, P.Geo. of North Face Software Ltd. and Paul Cowley, P.Geo. of Buena Tierra Developments Ltd., are Qualified Persons as defined in NI 43-101 and were responsible for the preparation of the Technical Report.
  7. An updated resource estimate is planned, as there are a number of new variables that apply, including; gold price, exchange rate, fuel costs, and the fact that the Lupin minesite would no longer be the processing site.
