The discovery of veining within several outcrops within the SE Alteration Zone is further evidence of the areas potential for hosting additional zones of epithermal mineralization.

Key Points: 
  • The discovery of veining within several outcrops within the SE Alteration Zone is further evidence of the areas potential for hosting additional zones of epithermal mineralization.
  • A map showing the location of the samples recently collected within the SE Alteration Zone is included below.
  • The Ixtaca deposit occurs in both the overlying volcanic rocks and the older underlying carbonate sedimentary rocks.
  • The Ixtaca deposit is one of several exploration targets on the Companys mineral claims, which cover an area of high-level epithermal clay alteration.

Knife Lake VMS Project Map:

Key Points: 
  • Knife Lake VMS Project Map:
    The Company's Knife Lake Project is located in Saskatchewan, which is ranked as the #3 mining jurisdiction in the world by the Fraser Institute.
  • The project hosts the Knife Lake deposit, which is a VMS, near-surface copper-cobalt-gold-silver-zinc deposit open along strike and at depth.
  • Knife Lake Project Geology and History:
    The Knife Lake deposit is a near surface remobilized VMS deposit starting a few metres below surface and the deposit remains open at depth and along strike for potential resource expansion.
  • The project hosts the Knife Lake deposit, which is a VMS, near-surface copper-cobalt-gold-silver-zinc deposit open along strike and at depth.

Garrett Ainsworth, President & CEO of District, commented: These Swedish properties provide District with significant opportunities in the prolific Bergslagen District, which is known for its large tonnage and high grade Volcanogenic Massive Sulphide (VMS) and Sedimentary Exhalative (SedEx) deposit types.

Key Points: 
  • Garrett Ainsworth, President & CEO of District, commented: These Swedish properties provide District with significant opportunities in the prolific Bergslagen District, which is known for its large tonnage and high grade Volcanogenic Massive Sulphide (VMS) and Sedimentary Exhalative (SedEx) deposit types.
  • The Bergslagen District has substantial polymetallic production and endowment that is evidenced by the numerous historical and active mines, which has seen little modern systematic exploration compared to peer districts.
  • Sweden is a stable and supportive jurisdiction for mining that is ranked highly by the Fraser Institute.
  • Mineralization on any other properties referred to herein is not necessarily indicative of mineralization on the Tomtebo and Trollberget Properties.

Cut-off grade is based on copper price of US$3.00 per pound and a metallurgical recovery of eighty percent, without considering revenues from other metals.

Key Points: 
  • Cut-off grade is based on copper price of US$3.00 per pound and a metallurgical recovery of eighty percent, without considering revenues from other metals.
  • The mineral resources are reported at a cut-off grade of 2.0%copper to reflect the reasonable prospects for economic extraction.
  • The mineral resources presented in the Mineral Resource Statement for the Rail Deposit in Table 1 are not mineral reserves and do not have demonstrated economic viability.
  • The Company owns and options several advanced-stage, high-grade copper and zinc dominant VMS deposits in the Snow Lake area of Manitoba.
