The Lone Star Mine, Republic Mining Camp, Washington State


  • Historic Resource Estimate*

Download Lone Star Technical Report 2007

  • Historic resource based on $593 oz gold
  • High Grade Intercepts are conducive to underground mining.
  • Historic underground workings in place
  • 2007 Report “property has potential for additional resources as many zones in the deposit remain open and untested to fully define their extent”
    “The areas with the most potential to expand the resource are located in the southern and eastern portions of the deposit and at depth below the pit outline.”
  • 2007 Report recommends 2,600 metres of drilling in 13 holes  with 10 of them testing outward from the southern cluster of thick high-grade zones, and 3 holes to test the expansion of an eastern thick, rich zone.
  • Shortly after 2007 Resource Estimation previous owner went into receivership due to 2008 economic crisis and the mine remained dormant ever since.
  • Belmont will be the first company to acquire and advance the Lone Star mine.

The Property

The Lone Star property is located in northern Washington State on the northeastern tip of the Republic Graben, an important geological feature which hosts several gold and copper mines.

The property is situated on a three kilometre long mineralized trend of gold-copper with past producing gold-copper mines and prospects, including No.7, City of Paris, Lincoln and the Lexington. This mineralized system is structurally controlled by the NW-SE  No.7 fault. The geology of the Lone Star Property is strongly influenced by the No. 7 Fault. The fault has
an acurate northwesterly trace on the Lexington Property to a southerly trace on the Lone Star Property.

The past producing Lone Star Mine operated over two time periods; from 1897-1918 producing 146,540 tonnes, and from 1977-1978 by Granby Mining Co. when 400,000 tonnes of ore were transported from the Lone Star open pit to its Phoenix mill in B.C, 11km to the north.

The 234 hectare Lone Star Property is comprised of a series of contiguous Washington State patented lode claims, and private mineral rights claims.

The claims cover a previously disturbed area from past underground and open pit mining and if a development program was considered, the open pit area could support an underground operation.
A portal could be established in a bench wall on the current pit and waste rock could be contained within the confines of the current open pit.

Lone Star Open Pit – Historical Resource
projected to surface

The Lone Star deposit is interpreted as a series of eight shallow to moderately dipping echelon overlapping zones hosted within a dacitic and minor serpentinite unit. Zones are composed of sheeted and stockwork pyrite-chalcopyrite veins, veinlets and disseminations carrying gold.

Belmont geologists have reconsidered the high-grade Cu +/- Au drillhole intercepts in the area of the historic resource for the potential to support an underground operation. Many historic Lone Star intercepts demonstrate underground mine widths and grade.

NI 43-101 Disclosure:

Technical disclosure in this news release has been approved by Laurence Sookochoff, P.Eng., a Qualified Person as defined by National Instrument 43-101.

 (1) Mineral resources which are not mineral reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues.

(2) The quantity and grade of reported inferred resources in this estimation are conceptual in nature.

(3) The mineral resources in this estimate were calculated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the CIM Standing Committee on Reserve Definitions and adopted by CIM Council December 11, 2005.

(4) Gold equivalent (AuEq) grade was calculated utilizing a gold price of US$593/oz and copper price of US$2.84/lb., based on the 24 month (at July 31, 2007) trailing average of gold and copper prices, to obtain a conversion factor of % copper x 3.284 + gold g/t = Au Eq g/t. Metallurgical recoveries and smelting/refining costs were not factored into the gold equivalent calculation.

(5) The Cu equivalent (CuEq) cut-off value of 1.5% was calculated and rounded utilizing the following: Cu price US$2.84/lb, $US exchange rate $0.88, process recovery $95%, smelter payable 95%, smelting and refining charges C$7/tonne mined, mining cost C$62/tonne mined, process cost $C28/tonne processed, G&A cost $7.50/tonne processed.

(6) A qualified person has not done sufficient work to classify the historic estimate as current mineral resources or mineral reserves.  As such the issuer, Belmont Resources, is not treating this historical estimate as current mineral resources or mineral reserves.
