The Tuscarora Gold Project, 50km northwest of Elko, is a high-level, low-sulfidation, epithermal gold prospect in the historic Tuscarora Mining District of Nevada, USA. Historic drilling intersected over 182 g/t gold in quartz-adularia veins at relatively shallow depths at Tuscarora. American Pacific optioned the property from Novo Resources, and is now drilling a staged 19 hole campaign to follow up on previous high grade drill results.

The Tuscarora district has had extensive exploration and mining in the past. Since the 1980’s, the gold-dominant, high-grade vein portion of the district has emerged with two distinct zones, the South Navajo Vein Zone and the East Pediment Zone.
The highest grades have occurred in these two zones. American Pacific phase 1 drilling concentrated on the South Navajo Vein zone, with highlights from the first 5 of 16 holes below, followed by NOVO Resource’s drill results from 2016 and Newcrest’s from the late 90’s.

American Pacific is now in the process of separating out high-grade samples to be re-assayed via Screen Metallic Analysis to compare to the Fire Assay results. In the past, previous operators saw some assays had a wide variance of grade when comparing Fire Assays to Screen Metallic. This is quite common in higher grade vein systems containing coarse gold. Screen Metallic analysis determines the content in both the coarse and fine material after the screening process, whereby the coarse material analysis is done separately, with the fine material usually analyzed in duplicate to achieve an average value. For systems with coarse gold Screen Metallic Analysis can be a more accurate and representative method of analysis. All samples that return 1 gram or better in the fire assay will be re-analyzed using this Screen Metallic method. Screen Metallic and duplicate assay work will be performed by the accredited ALS Global Laboratory.

All assay numbers are reported as un-cut and all intercepts are reported as drill width and are not to be interpreted as true widths. The assay values demonstrate narrow and discontinuous shoots of high-grade gold. Newcrest described coarse visible gold that created a metallurgical nugget effect as well (Jones, 1999).
Tuscarora has had extensive reverse circulation drilling in the past that has outlined two target zones. The historic drilling intersected high gold grades in quartz-adularia veins at relatively shallow depths. Historic results suggest that a staged exploration program can advance this property towards further discovery, and potentially a compliant resource.
The property consists of 91 claims covering approximately 1,818 acres within the Tuscarora Mining District in Elko County, Nevada. The Tuscarora District lies at the foot of Mount Blitzen on the eastern slope of the Northern Tuscarora Range.
There were several drilling phases with multiple holes containing gold mineralization within the South Navajo Vein and East Pediment areas. Historic drilling by Novo Resources and Newcrest outlined vein zones with 5 to 40 feet of gold mineralization intersected in drilling.
The work completed and data available are insufficient to determine the length, width, depth, or continuity of the mineralization. However, the mineralization indicated by these intervals indicate a more comprehensive work program is justifiable. The historic work is not of sufficient density and veracity to determine a quantifiable mineral resource or reserve.
Novo drilling descriptions indicate the higher-grade gold values and intervals are coincident with sulfide-bearing and oxidized quartz veins. These vein-zones are commonly within quartz-adularia altered tuff or are surrounded by chloritic zones in the tuff.

On November 6, 2017, American Pacific Mining Corp. (“APM”) entered into an option agreement with Novo Resources (USA) Corp. (“Novo”) to acquire a one hundred (100%) percent interest in the Property. For this option, APM will:
- Make cash payments to Novo of three hundred and seventy-five (CAD$375,000) Canadian dollars
- Deliver shares of American Pacific Mining Corp. stock equivalent to two hundred thousand (CAD$200,00) Canadian dollars
- Complete one hundred thousand (USD$100,000) U.S dollars per year in expenditures on the property
American Pacific Mining Corp may exercise the Option at any time after completing the cash and share payments. Following that the APM obligations will be:
- Pay a Royalty Interest to Novo of one-half percent (0.5%) of Net Smelter Returns which may be reduced to nil (0%)) by paying five hundred thousand (USD$500,000) US dollars.
- Pay a Royalty Interest to Nevada Select Royalty, Inc. based on the New York COMEX price of gold per troy ounce, payable as follows:
|Less than or equal to $1,500.00||Two percent (2.0%)|
|Greater than $1,500.00 but less than or equal to $2,000.00||Three percent (3%)|

The Tuscarora Mining District is within a major gold producing region of Nevada. Placer gold was discovered in the district in 1867 and production of silver-gold lode deposits began in 1875 (LaPointe, et al., 1991). Total precious metal production between 1867 and 1990 consists of 244,000 ounces of gold and 7,632,000 ounces of silver from quartz veins and quartz stockwork mineralization
Since 1982, the Tuscarora District has had a sustained, exploration effort. This effort has been almost continuous, with each subsequent operator building on the previous work. Ultimately, this work led to the area covered by the Tuscarora Project.
The Tuscarora Project lies south and east of the Dexter historic open-pit. Newcrest drilled this area and noted numerous significant gold values for the South Navajo Vein and East Pediment areas. With up to 5 feet, grading 182 g/t Au in drill hole TN38, in the South Navajo Vein area. Their assay values indicated narrow and somewhat discontinuous shoots of high-grade gold. Newcrest also described coarse visible gold that created a metallurgical nugget effect.
The Great Basin in Nevada is a westward thickening wedge of carbonate and siliciclastic rocks deposited along a craton margin over hundreds of millions of years. The regional structural setting is simply portrayed, as older Paleozoic and Mesozoic rocks above younger Paleozoic and Mesozoic rocks. Multiple global scale tectonic events pushed eastward, developing low-angle thrust faults that juxtaposed siliciclastic and carbonate rocks. In the late Mesozoic and early Cenozoic, extensional tectonic events led to multiple volcanic and intrusive events that continue into modern times.
In this region of the Great Basin, three lithologic domains developed during the Cambrian to Late Devonian. Shallow, platform carbonates and shelf-slope carbonates formed the earliest domain as a westward-thickening wedge along the passive margin edge of the North American craton. A second domain formed in the Ordovician from deep-water ocean basin siliciclastic, volcanic, and volcaniclastic rocks to the west. The third domain is the result of the Antler highland emerging along the leading edge of the Roberts Mountain Thrust with subsequent erosion and deposition of the sediments along the eastern margin of the highland and into the foreland basin.
In the early Tertiary, a period of extensive silicic volcanism occurred throughout a large portion of southwestern North America. The Tuscarora volcanic field developed during this period and is one of the largest examples of Eocene age magmatism in Nevada. The most intense magmatism occurred to the southeast in an area of ~175 miles that encompasses at least five major volcanic centers including the Mount Blitzen volcanic center.
The Tuscarora District clearly displays gold and silver in low sulfidation epithermal quartz-adularia veins and stockwork veins associated with dacitic intrusives and structures formed along the southeast margin of Mount Blitzen. The northern silver-rich portion of the precious metals district occurs immediately north of the Project. The silver-rich area has high Ag:Au ratios (>100), strong base metals, and typically displays narrow alteration selvages around quartz-carbonate veins hosted mostly in intrusive dacite.
In contrast the southern gold rich portion of the district, including the Tuscarora Project, have relatively low Ag:Au ratios (<15), contains almost no base metals, underwent local boiling, and displays widespread silicification and adularization along with quartz-adularia veins, stockwork veining, and vug-fills in tuffs and fine-grained epiclastic rocks.
Historical work has documented gold and silver production throughout the Tuscarora District. Several drilling phases with multiple drill holes intersected gold mineralization in the South Navajo Vein and East Pediment areas.
