Developing Canada's Next Gold Camp

The Indin Lake Greenstone Belt (“Indin Lake”), is home to one of the few remaining under-explored gold camps in Canada - the Indin Lake Gold Camp. It’s host to several gold deposits and showings, the most significant being the past-producing Colomac open-pit gold mine, located within the north-central portion of the Company's Indin Lake Gold Property.

Consolidation of the gold camp began in 2010 and culminated with the acquisition of the Colomac Mine and surrounding mining leases in 2012. Nighthawk has secured all the gold mines, deposits, and showings to become the first company to combine the camp’s best assets and prospective opportunities under one ownership.


An Untapped Archean Gold Camp


Indin Lake is geologically similar to many historic Archean gold camps renowned for their prolific production profile, with the exception that it has not been the subject of focused and continuous exploration. Indin Lake is underlain by stratigraphy similar in composition and age to the Timmins Gold Camp of northern Ontario, Canada (> 75 million ounces of gold production to-date), and the Kalgoorlie Goldfields of Western Australia (> 60 million ounces of gold production to-date). All three Archean terrains have also undergone several early periods of structural deformation including thrust faulting and folding; fundamental requirements to the formation of dynamic gold systems. Herein lies the opportunity, as Indin Lake has not undergone the 100 plus years of exploration and development that these two giants have experienced, yet it possesses the prerequisite characteristics that suggests the existence of a highly fertile gold camp.

The Company’s flagship asset, Colomac, is hosted by a differentiated sill of intermediate to mafic composition. This deposit type is almost non-existent in the Canadian landscape, however, differentiated intrusions are known to contain large gold deposits. One of the world’s largest, the Golden Mile Dolerite, is similar to Colomac as both host deposits within fractionated mafic intrusions in a stratigraphy dominated by mafic volcanic rocks. They also occur in similar age rocks, have similar strike lengths, have been subjected to similar styles and intensities of deformation and alteration, and contain gold preferentially concentrated within the more silica-rich (brittle) upper portions of the sills.

In 2012 Nighthawk established Colomac as a fractionated sill and recognised it as a Golden Mile Dolerite analogue (see press release dated June 20, 2012). Since then the Company has focused on developing the thesis that Indin Lake is home to a highly prospective and underexplored gold camp, with a previously unrecognized multi-million-ounce gold deposit that shares many similarities to the largest gold deposit within the world’s second most prolific Archean Gold Camp. From that point onward Nighthawk has pursued the recognition and cultivation of opportunities leading to the development of Canada’s next gold camp.

The Company has been working in the area since 2009, and over the years exploration activities have increasingly expanded to advance not just Colomac, but many of the other regional prospects through diamond drilling, airborne and ground geophysics, fixed-wing and drone LiDAR surveys, detailed geological mapping, structural studies, and prospecting. Indin Lake has never been subjected to this scale of attention and being at such an early stage of exploration, new discoveries, and in particular near-surface discoveries continue to be expected.


Summary of Exploration Activities to Date


District-scale Land Position with Numerous Gold Deposits and Showings

Within the extensive Indin Lake Gold Property (899 km2), Nighthawk has identified several high-grade showings and deposits with widespread mineralization in a range of styles that are largely hosted in brittle regimes, typomorphic of many productive high-profile Archean gold camps. The continued exploration success from the satellite targets supports Nighthawk’s conviction that the Colomac deposit is not the only multi-million-ounce opportunity capable of hosting high-grade mineralization. The many prospective regional targets provide a remarkable opportunity for growth and collectively strengthen the Company’s 100% controlled regional play centered on Colomac, a growing, multi-million-ounce gold deposit.

The following table summarizes some of the more prospective regional targets and showings within the Indin Lake Gold Property, including the work completed to date by Nighthawk. Most are at an early exploration stage and require additional work to realize their ultimate potential.
