Star Range Ag Sb Project

UTAH

The Star Range Project located ~6km west of the town of Milford in Beaver County, southwestern Utah, USA, and consists of 104 unpatented lode claims for 2,160 acres (8.74km2), consisting of two claim blocks, North Star and South Star Prospects.

HIGHLIGHTS

  • Project .located in Utah, consisting of ~2100 acres
  • Historical rock sampling includes bonanza silver grades up to 8,760 g/t Ag (309 oz/t) and antimony >1% Sb at surface6.
    • South Star Prospect significant rock samples returned:
      • 8,760 g/t Ag and +1% Sb
      • 1190 g/t Ag & 0.2% Sb
      • 938 g/t Ag and 0.2% Sb
      • 1,110 g/t Ag
    • North Star Prospect significant rock samples returned:
      • 1,310 Ag and 0.4% Sb
      • 1,380 g/t Ag and 0.5% Sb
      • 621 g/t At and 0.6% Sb
      • 3,620 g/t Ag
      • 2,920 g/t Ag
      • 3,900 g/t Ag
  • Historical soil programs delineated large silver anomalies – 1.5 km at North Star and 400 m at South Star – and to date no drilling completed across these zones6,10.
  • Majority of historical sampling did not report antimony, leaving significant upside potential.

OVERVIEW

LOCATION

The Star Range Project located ~6km west of the town of Milford in Beaver County, southwestern Utah, USA, and consists of 104 unpatented lode claims for 2,160 acres (8.74km2), consisting of two claim blocks, North Star and South Star Prospects.

Access is via numerous maintained gravel roads and tracks. Power lines and gas pipelines are located near the SE corner of the project, and Union Pacific Railway passes through Milford.

The Project is located proximal to two significant mineral occurrences, the historical Horn Silver mine and the Milford Copper Mine.

The Horn Silver mine, located 15km northwest of the Project was one of the largest producers of silver in the United States until 1930. During its production history the Horn Silver Mine produced 17 Moz of silver, 25 Koz of gold and 9 Mlb of copper, all from a single 20 acre (8ha) mining claim11. Total production from 1875 through 1952 (the last year of operation) was 835,000 tons averaging 21.5 ounces per ton of silver and 23% lead. A zone of supergene copper enrichment was mined mainly between 1899 and 1905.

Several open pit copper deposits are currently being mined by Milford Mining ~9km north of the project area. No resources or production figures are publicly available.

GEOLOGY

The Project is located within the Star Range in southwestern Utah, a site of intense historical mining activity until the mid-1960s producing lead, zinc, copper, gold and silver.

It lies within the structurally controlled Basin & Range style mountain range consisting of block faulted sediments, predominantly siliciclastics and carbonates of Palaeozoic to Tertiary Age. This package of generally north striking, east dipping sediments has been intruded and metamorphosed by intrusive rocks of granitic composition.

The Project area hosts numerous old workings, the majority of which were exploited in the late 1800’s for base and precious metals. Mineralisation is known to occur as structurally controlled Manto-replacement style and breccia vein systems along sediment contacts.

PREVIOUS EXPLORATION

Sporadic exploration has been completed by several companies over the last 20 years and details of publicly available exploration since 2012-13 provided below, with 372 rock samples and 406 soil samples identified from public domain sources. Antimony was not a primary focus for previous explorers.
