• Majuba Hill is a porphyry copper silver prospect located 70 miles southwest of Winnemucca, Nevada, 156 miles east-northeast of Reno
  • Moderate to strong Cu – Ag mineralization is found in the Majuba fault and parallel structures on this 4,198 acre property
  • Previous drill results include:
    113m at 0.45% Cu, 72.5m at 0.38% Cu, 86.8m at 0.27% Cu, 47.4m at 1.06% Cu
  • Majuba Hill has a history of production, a database of previous drilling, encouraging geochem results and good tonnage potential
  • A staged exploration program will target the original mine area and at depth below the historic workings

Overview

At Majuba Hill the property access, climate, and physical setting are all favorable. The site is remote from large population centers but not so much that it has wilderness value. Normal weather and climate of the area would not hinder year-round access or interfere with exploration and mining activities.

The project shows indications of a potentially large Cu – Ag +/- Au mineralized body with many features in common with both large porphyry copper and silver – tin type mineralization. Small scale historic mining concentrated on the Majuba fault zone and veins in subordinate structures. Drilling has identified a body of oxide copper-silver mineralization, but this body has not been fully defined or properly modeled to produce a mineral resource estimate. A few deeper drill holes, IP geophysical surveys, and surface geochemistry have tentatively identified target areas with potential to significantly expand the mineralization.

Location & Infrastructure

The Majuba Hill property is 113 road km (70 miles) southwest of Winnemucca, Nevada, and 251 km (156 miles) northeast of Reno.  Access is by well-maintained county roads from the Imlay, Nevada exit on U.S. Interstate 80, and traveling westward 23 miles. The project is in north central Pershing County, about 172 km (107 miles) northeast of Reno, Nevada. The nearest supply center is Winnemucca, Nevada. Winnemucca offers food, lodging, fuel, and some exploration services. All mineral exploration services including supplies, analytical laboratories, and drilling service companies are available in Reno or in Elko, Nevada, about 210 road miles to the east of the project. Reno and Elko are the major supply centers for exploration and mining activities in Nevada. The nearest airport with commercial service is Reno, Nevada.

The highways are sufficient for transportation of exploration-size heavy equipment. Development logistics would use the 4 lane Interstate 80 highway, Union Pacific railroad tracks and adjacent power, natural gas, and fiber optic transmission lines in the rail – highway corridor. A few four-wheel drive roads and ATV trails provide access to the main target areas. Mining is a common occupation in the area with several small to world class mines operating in the Winnemucca – Lovelock area over the past several decades. A well-trained and experienced mining workforce pool is available in Nevada that will flow to where it is needed.

    lbs. lead

  • 106,000

History

The Majuba Hill District was initially discovered in 1907 with the discovery of copper stained outcrops and cassiterite float. Mining for copper began during the price spikes for base metals triggered by the first World War. Since this is a rather isolated district, the history of the property is essentially the history of the region.

Other than the Majuba intrusive complex-related mineralization (including the Last Chance mine), mining in the district is confined to moderate-grade gold placer deposits on the southern flank of the Trinity Range. Reports of examinations of these placers indicate the source is not likely to be Majuba but gold locally derived from small quartz veins in metasediments (Jenkins, 1982).

The history of Majuba Hill itself can be divided into two periods: production and exploration. The early part of the 1900’s saw high-grade copper production and minor tin production from oxidized ore at the Majuba Mine. Peripheral silver, lead, and zinc was mined from the Last Chance Mine. Exploration has occurred since the 1970’s as the porphyry system was recognized and defined. Modern exploration began in 1971 with Mine Finders, Inc. of Lakewood, Colorado initially looking at Majuba Hill as an analog to the porphyry molybdenum orebodies mined in Colorado. 38,498 feet of core and RC drilling has been completed since 1970: 19,834 feet of core by Mine Finders (1970-1974), 8,560 feet of RC by Minterra Resource Corp. (2006 -2008), and 10,104 of core by Max Resources (2011-2014).

Majuba Hill Exploration Model

Small scale historic mining concentrated on the Majuba fault zone and veins in subordinate structures.

Between 2007 and the present, 35 holes with a total of 18,584 feet were drilled at Majuba. Prior to this, 28 holes with a total of 23,316 feet were drilled between 1920 and 1975. Drill logs and assays for the historic drilling are available in various formats. The modern (2007 and later) drilling records are in very good condition and have been converted to electronic format along with all assay certificates and results. Core and chips are stored in Elko, Nevada for the modern drilling.  Drilling has shown significant intercepts of low grade copper and silver in both oxide and sulfide mineralization.






Drill holes have drilled down through the oxide into the “big prize”: sulfide mineralization

Holes have been angled holes from the side, or angled holes from underground-starting below the oxide
