1.0       Ellendale Diamond Project Summary

Gibb River Diamonds Limited (‘GIB’ or the ‘Company’) owns the mining and exploration leases (100%) which cover the Ellendale Diamond Project in the West Kimberley, WA. The Ellendale Project has been one of the world’s foremost diamond producers with past production of approximately 1.3 million carats. This included the annual supply of over 50% of the world’s Fancy Yellow diamonds, which were the subject of a special marketing agreement between the former operator and Tiffany & Co.

The Company’s aim at Ellendale is to progress and permit areas which can be brought into profitable production as quickly as possible. A number of exciting targets at Ellendale include:

  • E9 Alluvials
  • Blina Alluvials
  • Dredging mineralisation within the existing E4 and E9 pits
  • Assessing existing E4 & E9 ROM pad stockpile and lights volumes and grades
  • Studies on recommencing hard rock mining at E4, E4S and E9
  • Numerous other alluvial and hard rock targets

GIB believes there is enormous potential for the new Ellendale leases to deliver a profitable diamond mining operation and this potential is currently being assessed by GIB. This magnificent opportunity allows the Company to develop this exciting area and move towards our goal of becoming Australia’s next diamond producer.

With the Blina Alluvial Targets fully permitted for mining and ‘shovel ready’ and assessment of the other Ellendale prospects and former mining operations already underway, the Company is in an excellent position to set up an immediate diamond pipeline of development projects.

2.0       Ellendale Diamond Project Leases Acquisition

GIB acquired the Ellendale Diamond Mine leases in December 2019 under an EOI process run by the State Government. This acquisition delivers leases over the Ellendale Diamond Project through the pegging of standard tenements and brings with it no environmental or other legacy liabilities.

These leases cover the most prospective ground at Ellendale (Figure 1), including the two previous hard rock mines at E4 and E9 and all of the previous extensive alluvial mines, workings and prospects. GIB will ensure that the grant of the key tenements is expedited as swiftly as possible.

3.0       Ellendale Funding

Ellendale Project financing is required to commence the above operations and studies. This includes operational capital to conduct four months of bulk sampling operations and trial mining at the Blina Alluvials Prospect. The capital required is a modest $2.5 million and the Company is currently looking at ways to raise this capital, including through the sale of GIB’s wholly owned Highland Plains phosphate deposit. The Company is debt free.
