Goliath Resources Limited has disclosed the findings of a study of mineralized specimens from the Surebet Zone done by Dr. Thomas Monecke and T. James Reynolds of the Colorado School of Mines. The Surebet Zone is a portion of Goliath’s fully managed Golddigger Property in British Columbia’s Golden Triangle.
Summary of Findings:
- Dr. Thomas Monecke and T. James Reynolds of the Colorado School of Mines concluded from a petrographic and fluid inclusion study of mineralized specimens from the Surebet Zone that this recently found mineralizing system is intrusion-related and constituted at a significant depth, over 56 km below paleosurface.
- The discovery of Surebet’s deep-rooted, intrusion-related formation signals enormous exploration potential at Goliath’s 100% owned Golddigger project in British Columbia’s Golden Triangle. Since the causal intrusion is thought to be considerably down-dip to the west of Surebet, mineralization is expected to continue beyond the current drilling limitations, which are approximately 1.1 km down dip from the outcropping Surebet Zone. It is also plausible that faulted offsets of the Surebet Zone, such as the New Extension Target to the southeast of Surebet, have yet to be located elsewhere on the property.
- There are two forms of hydrothermal vein quartz: 1) early quartz, which formed under lithostatic circumstances, and 2) later quartz, which was shaped under hydrostatic conditions and crosscuts earlier quartz. Vein quartz formation occurred at the transition from ductile to brittle behavior, at high temperatures of ~350‒400 ⁰C, during a period of total cooling of the hydrothermal system, according to fluid inclusion evidence. As the hydrothermal fluids rushed into an open network of freshly produced brittle fractures, the wall rocks near the Surebet structure changed from ductile to brittle behavior, causing a change in pressure.
- Sulfides occur in combination with, and/or after, second-generation quartz and crosscut early-stage quartz. When fluid flowed via a more accessible fracture network, mineralization evolved under hydrostatic conditions.
This first-ever study of the formational environment of the Surebet Zone provides strong support for significant upside potential at Surebet and elsewhere across the Golddigger property.

Dr. Hennigh was also a strategic shareholder of Goliath Resources.
“Surebet is a deep-rooted intrusion-related gold deposit, one that is likely expansive. The causative intrusion probably lies well down-dip of Surebet to the west indicating we have lots more room to explore this strongly mineralized zone down dip. Logically, lateral but down-faulted segments of the Surebet system will be discovered to the north and south,” he added.
Dr. Hennigh also stated, “The New Extension Zone immediately southeast of Surebet is a likely example. With this intrusion-related model in hand, Goliath is very confident to step out boldly with future exploration efforts.”
“This year, Goliath will undertake a three-pronged approach to explore Golddigger:
1) to drill as much as 24 km of the diamond core at Surebet, some holes as far as 1.5 km down-dip from where Surebet outcrops, 2) to conduct inaugural drilling at the New Extension Zone to test whether this is indeed a major extension of Surebet, and 3) to aggressively pursue prospecting for new zones of intrusion-related mineralization across the property. Goliath is set to have a very productive 2022,” Dr. Hennigh concluded.
