Geological Framework



Cliff-Nina is an extensive (4.0 km x 0.5) Porphyry Copper-Gold corridor on the southern portion of 7.5 km long Hawilson Monzonite complex. This corridor is proximate to the Triassic-Jurassic unconformity, referred to as the “Red Line” (Kyba 2014) an important geological horizon for

Porphyry Cu-Au mineralization isassociated with ~400 m wide and 4 km long, dike swarm of Jurassic age (191 Ma) monzodiorite intrusions and breccias hosted by upper Triassic Stuhini rocks. The intrusions are characterized by typical coarse-grained porphyritic textures with plagioclase feldspars and amphiboles as well as hydrothermal biotite, chlorite, sericite and clay alteration minerals. The porphyry intrusions and breccias exhibit strong potassic and sericitic alteration, quartz-carbonate veins and sulfides; cut by narrow late-mineral to barren diorite dikes.

The structural setting and the interplay between porphyry intrusions, breccias and alteration events are responsible for the gold-rich mineralization at the Cliff-Nina porphyry target which remains open in all directions”. The geological characteristics, metallogeny and copper-gold grades at Cliff-Nina porphyry corridor is similar to the Kerr Deposit of Seabridge Gold’s KSM project, which has an inferred resource of 1.92 billion tonnes grading 0.41% copper and 0.31 g/t gold, containing 19.0 million ounces of gold and 17.3 billion pounds of copper (Seabridge New Release Feb 16, 2017).

2018 Exploration and Drilling Program



The 2018 exploration program at the Cliff and Nina targets comprised 7 deep diamond drill holes totaling 3,406 meters, yielding intervals of significant gold-rich mineralization. The drilling assays confirmed the continuity of copper-gold grades along the Cliff-Nina porphyry corridor, extended over a strike-length of 4 km, at the southern end of the 7.5 km long Hawilson monzonite. The Cliff-Nina corridor is identified as a unique porphyry system with three distinct styles of copper-gold mineralization given below in chronological order.
  • Extensive gold-copper intervals (i.e.141 meters of 0.4 g/t Au and 0.23% Cu in hole KH18-16) are associated with a swarm of potassically altered Hawilson Monzonite dikes.
  • Broad intercepts of gold-rich mineralization such as 37 meters of 1.54 g/t Au and 0.05% Cu in drill hole KH18-14 are linked to secondary hydrothermal event of intense quartz-carbonate veins and highly silicified hydrothermal breccias along the contacts with the Hawilson Monzonite dikes.
  • Localized 1-3 meter intercepts with gold grades up to 3.0 g/t Au are associated with late-stage quartz-carbonate and massive sulphide veins of pyrite-pyrrhotite-chalcopyrite mineralization.
A summary of the drilling results is tabulated below. All other maps and figures including geological maps, cross sections, model and field photographs are given in the photo galleries.
