ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS


RESULTS OF OPERATIONS

GENERAL

The Company was formed on July 13, 1988. On December 21, 1995 the Company
announced that it had completed the sale of its Sanchez Project and a 70%
interest in its Mexican project, the Piedras Verdes, to Phelps Dodge Corporation
for $40 million. All material revenues since the sale have been a result of
interest earned on the proceeds of the sale of assets to Phelps Dodge
Corporation.

The Company is currently focused on the construction of facilities to produce
high quality Muscovite Mica from its 100% owned Black Canyon Mica project
located in Arizona. The Company, with its 30% interest, has established a
strategic partnership with Phelps Dodge Corporation on the Piedras Verdes copper
project located in Sonora, Mexico.


THREE MONTHS ENDED SEPTEMBER 30, 1999 COMPARED TO THREE MONTHS ENDED
SEPTEMBER 30, 1998.

The net loss for the three months ended September 30, 1999 was $285,161 compared
to a net loss of $729,159 for the three months ended September 30, 1998. The
decreased net loss is the result of reduced exploration expense in the current
period. The Company realized income of $227,500 from the sale of exploration
camp assets in Mali during the current period.

Exploration expense was $134,538 for the three months ended September 30, 1999
compared to $570,412 for the three months ended September 30, 1998. The decrease
in exploration expense for the current period is the result of decreased
expenditures on the Mali project and on the Company's gemstone initiative.

During the three month period ended September 30, 1999 the Company expended an
additional $1,229,500 on the construction of facilities relating to the Mica
project. Through September 30, 1999 the Company has expended a total of
$4,086,473 on the development of the Mica project.
