MINERALS YEARBOOK, 1978-79 
 
develop a $5 million national registry of mines (estimated at 14,000 concessions)
which would establish location and concession boundaries as well as categorize
type and reserves of each concession. This plan hopes to minimize future
litigation and foster further foreign investment if titles are clear. The
survey covered 250 concessions in 1978 and 1,200 more in 1979. In 1979 the
Chilean Government concluded technical cooperation and/or economic agreements
with seven nations including 
Mainland China and also made an agreement with Egypt that provides for petroleum
sales to Chile. 
 Mining investments in Chile receive no special tax concession, and there
are no tax preferences given to domestic producers over foreign investors.
A foreign mineral investor may choose between a tax rate of a fixed 49% for
10 years or a varying tax structure that in 1978 amounted to 49.5%, which
is the rate paid by the state entities (CODELcO, etc~). 
 
PRODUCTION 
 
 The increase jn copper production in 1979 from 1978 resulted from gains
in three of the four CODELCO mines. Molybdenum, a byproduct of copper mining,
attained a peak level in 1979 as a result of efforts for improved recovery.
The continued decline in onshore production of petroleum was more than made
up by an increase in offshore production in the Straits of' Magel 
lan. But domestic production met only 23% of domestic consumption; this figure
may increase to 35% by yearend 1980. Although a great deal of attention is
being given to developing Chile's coal resources and expanded production,
production in 1978 and 1979 continued to decline. Coal production for 1980
is estimated at 1.6 million tons, 400,000 tons below estimated demand.
