INTRODUCTION
•
Marathon Gold Corporation is engaged in an exploration
and research program to determine the feasibility of mining
and processing placer gold and rare earth deposits found in
Moffat County, Colorado . A mining permit was sought by and
granted to Marathon in order that the Company be permitted to
conduct pilot plant and laboratory tests to obtain valid assay
and metallurgical data on gold and rare earths . Marathon desires
to make an amendment to its regular ( 112 ) permit to allow for
the laboratory use and testing of cyanide solutions in gold
assay and recovery research.
This amendment does not affect the operation of the
Company ' s wet gravity pilot concentration plant . The pilot
plant will continue to be run on an intermittant basis to recover
the gold bearing heavy mineral suite from bulk samples obtained
by Marathon. The pilot plant does not use cyanide, froth-flotation
or any hazardous chemicals .
Research and testing with cyanide solutions will be
conducted in the Company' s research and assay laboratory located
on site. All tests will be conducted in an especially designed,
environmentally safe area of the laboratory . At no time will
any cyanide be released into the environment. All solutions
• or ore pulps which have come into contact with cyanide will
be neutralized and disposed of in the lined laboratory waste
disposal site.
Marathon intends to continue test excavating and bulk
sampling of the one acre Joker Pit. There are no plans to expand
beyond the one acre of mining currently bonded for. The Company' s
emphasis is on exploration and development of large tonnage
channel deposits found elsewhere on Marathon' s properties.
The approved permit is incorporated herein by reference
to the extent said permit is not inconsistent with this amendment.
