The Lone Star Mine, Republic Mining Camp, Washington State
- Past producing mine
- 2007 Historic resource
*note resource is considered historic only in the fact that a change of ownership has taken place.
- 43-101 technical report states that the resource estimate is considered appropriate for use in a Preliminary Assessment or Scoping Study.
- Further in fill drilling has potential to move resource to Feasibility level
- Property has potential for additional resources as many zones in the deposit remain open and untested to fully define their extent.
Project is drill ready.
- Property is patented claims which is considered to be private land and as such no drill permitting required.
- Water for drilling available on property
- Drilling company available for drilling early November 2021
- Good road access and only minutes away from community
- Washington state based 43-101 QP geologist familiar with Lone Star is currently on contract to oversee drilling.
- Open pit and or underground
- Underground proposed ramp: Ramp at 15% approx. 530 m long decline 3x5m
- Open Pit stats:
- 25 up to 30 feet (7.62m) Benches at 60 to 70 deg
- 125 feet overall slope height at ~ 25 deg
- 800ft x 800ft = 640000 ft² = 14.6923 acre pit area
- 200 tpd toll mill within 17kms of project
*note mill is currently being refurbished and is estimated to be in operation when Lone Star achieve production status.
- Historic resource based on $2.84/lb Copper and $593 oz Gold
- Company plans to update resource with current metal prices (~$4.00/lb Copper and $1,800 oz Gold)
- High Grade Intercepts are conducive to underground mining.
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 was previously owned by Merrit Mining. In 2007 Merrit had completed a 43-101 Technical Resource Report and were about to produce a Preliminary Economic Assessment report but due the market crash Merrit Mining went into receivership and the property remained dormant until purchased by Belmont.
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. The Lexington mine is owned by Golden Dawn Minerals and has a Current Resource and a Preliminary Economic Assessment.

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 accurate 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.
The 2007 Technical Report states that: “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 open pit and 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.”

NI 43-101 Disclosure:
Technical disclosure in this web page 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.
