The company's flagship projects, located in New South Wales (NSW), Australia, have district-scale potential. NSW lies on the east coast of Australia and has been established as a prospective state for gold exploration and production since the 1850s. Between 2015 and 2016, NSW produced over 37 tonnes of gold, valued at AU$1.9 billion. Sentinel's property package in NSW includes 94,500 hectares and eight gold projects. At least 198 historic gold mines and gold exploration prospects are present across the NSW property package. Historic production records indicate that gold grades were often multi-ounce.
Sentinel has also acquired, through staking, seven silver-focused exploration concessions totaling 38,600 hectares in NSW. Sentinel's property package includes at least 23 historic silver and three historic gold mines and exploration prospects. Historic production records indicate high-grade silver production that exceeded 1 kg/t. Sentinel's technical team is currently reviewing historic data in order to fast-track reconnaissance follow-up and definition of high-grade, drill-ready targets.
Rob Gamley, president and CEO of Sentinel, commented, "The acquisition of eight strategically located gold projects within the prolifically mineralized Lachlan and New England orogenic belts provides the company with an extremely solid exploration portfolio on which to build. To acquire such a commanding land package, with numerous high-grade historic gold mines and showings, is a remarkable achievement given the large numbers of companies that are now focusing their acquisition and exploration activities in New South Wales. Our highly experienced team continues to review precious metal opportunities worldwide." The company's NSW property package is 100 percent owned with no NSRs, back-in rights, future cash payments or royalties.
Sentinel recently appointed a seasoned technical team with a proven track record of success in exploration. Gamley stated, "We are delighted to announce the appointment of such an experienced exploration and development team, which has over 90 combined years of experience in over 80 countries, across almost all commodities and deposits types, from grass roots through to resource definition and advanced project development. The technical team has significant public market experience and understands the importance of economically focused, results-driven exploration."
The company's property portfolio also includes the Salama project in Peru and the Waterloo project in British Columbia. The Waterloo property can be found 65 km east of Kelowna, near the historic Lightning Peak, a high-grade gold and silver mining camp. Several high-grade drill targets have been identified on-site. While the area has received attention historically, the Waterloo property has never been systematically drilled — Sentinel intends to capitalize on the significant potential for low-cost, high-grade gold and silver development.
The company's Salama project consists of four gold-focused exploration concessions totaling 2,700 hectares located in the Anta province of Peru. The project is situated within the prolific gold-polymetallic Miocene skarn and porphyry belt. More than 20 million ounces of gold has been produced within a 45 km radius of the Salama concessions from established mines such as the Lagunas Norte, La Virgen, La Arena and others.

New South Wales Project (Australia)
Sentinel's current NSW portfolio includes high-grade gold and silver orogenic projects. The portfolio consists of eight gold-focused concessions (Star of Hope, Golden Bar, Alliance Reef, Stanleys, Lady Mary, Waddery West, Wittagoona Reef and Toolom South) and seven silver-focused concessions (Wallah Wallah, Stony Creek, Carrington, Dartmoor, Glens Skarn, Broken Hill West and Goongong). At least 198 historic gold mines and 23 historic silver mines and exploration prospects are present across the entire NSW property package. Historic production records indicate that gold grades were often multi-ounce and that silver grades were generally high-grade and exceeded 1 kg/t Ag in some instances.
Five of Sentinel's eight NSW gold projects are located within the New England orogenic terrane, which hosts an extensive network of alluvial gold fields and, historically, has attracted a significant number of underground gold and silver mines. For instance, Toolom South, one of Sentinel's NSW gold projects, covers 165.5 square kilometers that includes over 60 historic gold mines and high-grade gold showings. Another project, Alliance Reef, traces 12 kilometers of the significantly mineralized Peel-Manning fault system. The Golden Bar covers nearly 200 square kilometers of the historic Orara-Coramba gold field.
Three projects are located within the Lachlan orogenic terrane of New South Wales, Victoria and eastern Tasmania. The Lachlan terrane is similarly prolific when it comes to economically significant mineralization of precious metals. The Stanleys property encompasses 90 square kilometers, and the land has hosted 17 historic gold mines and high-grade showings. Historic records cite production grades of up to 185 g/t gold. The Lady Mary property indicates 15 historic hard-rock mines and prospects. The primary target on the Warraderry West property is a 15 km gold-mineralized dyke swarm.
Six of Sentinel's seven NSW silver projects are located within the Lachlan Orogenic terrane, which comprises a series of well-mineralized accretionary terranes formed during the Ordovician and Early Carboniferous Period, making the exploration potential for silver excellent. For example, the Wallah Wallah covers 99 square kilometers, including 6 historic high-grade silver mines. Historic records indicate several thousand tonnes of material was processed at grades of 950 g/t Ag and 30 percent Pb.
Stoney Creek, another project, is an 81 square kilometer license hosting 7 high-grade historic silver and gold mines and showings. Carrington contains a number of historic mines and workings within gold-silver mineralized gossanous lodes; historic rock chip grab samples of this material assayed up to 85 g/t Au, 6037 g/t Ag, 24.85 Pb and 16.75 percent Sb. In the Curnamona Province, the Broken Hill West project is located 2.5 kilometers west of the Broken Hill mine complex and shares the same geological setting and structure.
The evaluation of all 198 historic mines and prospects in phase one is almost complete. Selection of the top 50 percent ranked targets will be prioritized for phase two and the remaining 50 percent will be considered for joint venture or subsequent development. Phase two of exploration involves geological mapping to estimate maximum depths, strike continuity and other critical details. A combination underground and surface regolith sampling will verify historical sampling grades and extend mineralised surface footprints. Data from phase two will inform geochemical surface sampling and geophysical surveys in phase three, which will focus on identifying robust drill-ready targets.
Salama Project (Peru)
The Salama property totals 2,700 hectares in the Anta province of Peru. The property is situated within the prolific gold-polymetallic Miocene skarn and porphyry belt, one of several metallogenic belts that run parallel to Peru's coast and have hosted the country's most significant deposits. Preliminary reviews reveal an extensive network of quartz veins with localized silicified breccias, which have been the focus of high-grade historic gold mining in the area. Historic production at the nearby La Virgen gold mine totaled 12 Koz gold per annum.
Waterloo Project (BC, Canada)
The Waterloo property covers 3,130 hectares in Kelowna, a mining-friendly jurisdiction located within British Columbia. Historically, the property has hosted a number of high-grade gold and silver operations since the early 1990s. High-grade prospects define a 4 kilometer strike from east to west, underscoring the potential for high-quality resource development that benefits from existing infrastructure.
