Location and accuracy This prospect is in the southern Shotgun Hills near the top of an upland west of the headwaters of an unnamed north tributary to the King Salmon River. It is in the NW1/4 section 9, T. 3 N., R. 51 W., of the Seward Meridian. The location is accurate to within 1/4 mile.

Geologic setting

Geologic description

Clark and others (1970) collected rock samples for about 5,000 feet along the crest of this upland. Several of these samples have weakly to strongly anomalous concentrations of silver (to 7 parts per million (ppm)), arsenic, boron, bismuth, copper, lead, antimony, tin, gold (to 0.1 ppm), and mercury. Bedrock is mostly hornfels in mid-Cretaceous clastic sedimentary rocks of the Kuskokwim Group. Clark and others (1970) describe this hornfels as strongly limonite stained and cut by numerous small quartz veins rarely exceeding 1/8 inch in width. Some of the quartz veins carry minor amounts of arsenopyrite and arsenopyrite is also locally disseminated in the hornfels. Some scorodite and malachite are locally present.
Cominco examined the prospect during a reconnaissance exploration program in the early 1980s (Travis Hudson, personal knowledge, 2005). Felsic intrusives cut hornfels and intense tourmaline alteration is locally developed. Shot was originally considered a tin-silver prospect and stream sediments, panned concentrates, and rock samples do contain anomalous tin values. Rock samples collected during initial exploration contained up to 510 ppb gold. TNR Gold Corporation (2005) explored this prospect in 2005 as part of their district exploration program centered on the Shotgun prospect (TA007). TNR drilled 301 meters in 2005 (TNR Gold Corp., 2014). In 2008, a revised NI 43-101 technical report was published (Harrop, 2008). In 2013, another NI 43-101 Technical Report was published (Van Wyck and Armitage, 2013).

Mineral deposit model Quartz veins in hornfels and felsic intrusive rocks; possibly polymetallic veins? (Cox and Singer, 1986, model 22c)
Mineral deposit model number 22c?
Age of mineralization Probably Latest Cretaceous, the age of intrusive rocks and mineralization in the similar Shotgun (TA007) prospect nearby (Rombach, 2000).
Alteration of deposit Silicification and tourmalinization (Rombach, 2000).

Production and reserves

Workings or exploration
Originally found during regional mapping by the U.S. Geological Survey in the late 1960s Examined by Cominco Exploration in 1981 during an initial reconnaissance of the area. TNR Gold Corporation was exploring this prospect in 2005 as part of their district exploration program centered on the Shotgun prospect (TA007).
TNR drilled 301 meters in 2005 (TNR Gold Corp., 2014). In 2008, a revised NI 43-101 technical report was published (Harrop, 2008). In 2013, another NI 43-101 technical report was published (Van Wyck and Armitage, 2013).
Indication of production None
Reserve estimates Though the Shot prospect does not have any calculated resources or reserves, a resource estimate on the nearby Shotgun prospect (TA007) was completed in 2013 (Van Wyck and Armitage, 2013).
Production notes None.

Additional comments

In 2010, TNR Gold Corp. announced an increase to 100 percent undivided ownership interest in the Shotgun project through the acquisition of NovaGold Resources outstanding 50 percent (TNR Gold Corp., 2010).
