SY Property, Nunavut (Yathkyed Lake Greenstone Belt)

Why it’s Compelling

  • District-scale footprint: ~45,984 ha across 44 mineral claims in an Archean greenstone belt geologically analogous to Meadowbank and Meliadine, two of Nunavut’s marquee gold camps. 
  • Proven gold endowment: >40 documented gold occurrences and ~20 high‑grade showings over ~30 km of strike, with historic surface samples up to 38.8 g/t Au.  
  • Historic intercepts already in hand:
    • 3.38 g/t Au over 3.5 m and 3.18 g/t Au over 7.0 m (1986 drilling). 
    • 3.53 g/t Au over 6.2 m incl. 5.67 g/t Au over 3.0 m (1987 drilling, Jaeger East).
  • Modern geophysics lights it up: A 2006 DIGHEM V airborne survey outlined 690 EM conductors, many coincident with iron formations and contacts, classic settings for BIF‑hosted gold. 
  • 2007 confirmation & new showings: 102 rock grabs; 13 samples >1 g/t Au, five >5 g/t Au to 8.88 g/t Au, validating the geophysical targeting approach and adding new sulphide zones in iron formation and metavolcanics. 

Where The Ounces Could Come From

  • Banded Iron Formation–hosted lodes: Multiple horizons (oxide & silicate facies) with sulphides, arsenopyrite and strong deformation, exactly the kind that hosts Meadowbank/Meliadine ounces. 
  • Conductive, magnetic corridors: The 690 EM anomalies + linear magnetics define numerous untested bedrock conductors that match the BIF/sulphide model.

Why it Hasn’t Been Drilled Out Yet

Poor exposure + historic data gap: Extensive till cover and no comprehensive modern program until the 2006–2007 work. Little to no exploration since 1987, this is an underfollowed, data‑rich opportunity looking for systematic follow‑up.

Immediate Value Catalysts

  1. Tight ground geophysics over priority EM/mag trends to rank conductor clusters for drilling.
  2. Systematic soils/frost‑boil geochem to extend the 2007 success beneath cover.
  3. Focused Phase‑1 drilling on the best conductor + BIF + geochem overlaps to replicate/extend the historical high‑grade intercepts.

Key Takeaways

SY already checks the boxes: scale, multiple high‑grade hits, and a modern geophysical pipeline of 690 untested EM targets. With minimal modern drilling, the discovery curve is wide open.
