Use of marble is becoming more popular for
interiors and exteriors. Brian says maintenance
or life span is not a major consideration
and he would use marble in design if budget
permitted, but it is usually too expensive a
luxury. Synthetics are used because of
weight and budget considerations.

gray marble.

Dan said that there would be a market for
dark gray or black marble. Because of the
problems with foreign imports and predictability
he would like to see a more accessible
supply.

Chevron USA, Land Department, Andy Balch,
(415) 894-2591, November 9,1989
Contacted Chevron to establish a discount
factor with risk. Chevron uses a high risk,
low, and expected for rate of return. A no
risk rate of return is cost of capital plus two
percent and that would be used for a pipeline
type of investment. A land acquisition
for "strategic reasons" would be up to 15 percent
but usually is 14 percent, a high risk
purchase is between 20 percent and 25
percent.

To get 30,000 cubic feet of production gross
not net. requires two wire saws at $25,000
each, two drills at $18,000 each, pneumatic
hammers, quarry bar and 300 cfm compressor
for $50,000, derreck or used 988 front loader,
either is $100,000, diesel generator. He told me
that the weather is a drawback. No quarry
people work when it is raining or snowing and
must consider the length of season.

These consultants evaluate quarries for
production capabilities. Gere said that Black
Marble has a good market and dark gray
does not necessarily have a good market. He
said he would have to have a sample and
that he would then tell me if there is a
market.
Christian Marble Company, (919) 828-8001,
Derek Hardy, April 13,1989
He is a fabricator, said three cubic feet is too
small—needs a minimum of 4 ft by 5 ft by 8
ft. Most important aspect is how well it
polishes especially if black marble which
doesn't often polish very well. He does use
marble chips in his terrazzo business which
utilizes cement or resinous binder but still
must take a good polish. Transportation
would make Colorado production more
expensive.

They deal with 12in. by 12in. by .375 in.
tiles of Ebony and Negro Marquina and
special tiles of 18 in. by 18 in. by .375 in..
They are used some in floors but are usually
not hard enough to maintain shine. These
people have no interest in the product from
Colorado. The Ebony and Negro Marquina
sell very well.
