Geological Review of Golden Cup and Big Rush Completed

Great Northern Minerals Limited  is pleased to advise that a detailed data review of the Golden Cup and Big Rush projects, located 150 km west of Townsville Qld, has now been completed with particular focus on the geological setting of each gold deposit. This work has provided a number of compelling drill targets which will be tested as soon as the company finishes its current fund raising.

The work involved relogging and reinterpretation of the recent successful drill programs beneath the Central Pit at Big Rush and Golden Cup which had returned a number of significant intersections including (See ASX announcements dated 12 December 2019 and 28 January 2020):

BIG RUSH

  • BRRC1009: 24m @ 4.0 g/t Au and 2m @ 35.2 g/t Au
  • BRRC1004: 27 m at 2.7 g/t Au including 5 m at 12.6 g/t Au
  • BRRC1008: 29 m at 2.2 g/t Au including 3 m at 14.5 g/t Au

GOLDEN CUP

  • GCRC074: 7 m at 7.5 g/t Au including 1 m at 43.2 g/t Au
  • GCRC078: 9m at 4.7 g/t Au including 3 m at 11.5 g/t AuBased on the age and type of the host rocks, structural setting and sulphide mineralogy, an analogy with Fosterville is apparent, and assists with the Companys’ geological targeting. Similarities between Big Rush, Camel Creek and Golden Cup with Fosterville are documented below:
  • Similar rock types and age of the host rocks – folded carbonaceous horizons critical;
  • Mineralisation related to oblique structures intersecting anticline and syncline axis;
  • Comparable arsenopyrite-pyrite-stibnite sulphide mineralogy and quartz veining (see photo)
  • Drilling to date at Big Rusha and Golden Cup equivalent to the upper parts of Fosterville; and
  • Original resource at Fosterville similar tonnage and grade to the Golden Ant Goldfield.

Deep drilling in 2015 at Fosterville below the shallow modest resource unlocked the deep potential by intersecting bonanza free gold ore zones. Similar depth potential is believed possible at both Golden Cup and Big Rush and drill targets have now been defined from the recent review.
