Re: Florida Canyon Mine Mercury Questionnaire Addendum

Dear Mr. Bamford:

Florida Canyon Mining Inc. (FCMI), has prepared the enclosed Addendum to the Florida

Canyon Mine Mercury Questionnaire received by the Bureau of Air Pollution Control March 21,

2006. The Addendum consists of new annexes for the assay laboratory, pregnant tank, and

barren tame

Please append the new annexes to the original questionnaire. FCMC regrets the inadvertent

omission of the assay laboratory, pregnant tank, and barren tank from the original mercury

questionnaire response. Should you have any questions or require additional information, please

do not hesitate to contact either Mr. Clay Postlethwaite of Enviroscientists, Inc. at (775)

826-8822 or me a the address on the letterhead above or call me at 775/538-7300 ext 175.

Sincerely,

I~. J2:~- ~B::-~

QUESTIONAIRE ADDENDUM

ANNEX 7. OTHER THERMAL PROCESS UNITS

Please provide an identification of other thermal process units, including a

process description and the mechanism by which mercury emissions are released.

(Note: if facility has more than 1 "other thermal process" process, copy this

Annex 7 and complete a separate copyfor each such unit.)

a. Description: Assav Laboratorv

Includes 2 hot plates. 2 atomic adsorotion analytical instruments. 2 fire assay

furnaces. 1 cupellation furnace. and four drying ovens.

An estimate of the actual mercury air emissions released from such unit and the basis of

such estimate, in accordance with the following hierarchy of data:

. Direct testing and measurement.

. Based on engineering calculations that take into account the average

mercury content of the ore processed, the amount of ore processed and the

potential for mercury releases from the specific processes utilized to

recover gold.

Estimated mercury emissions from unit = pounds for 2004

Basis of estimate:

Circle the code numbers for the type of air pollution control device and the type of fume
