This is Oyu Tolgoi's discovery ann by Ivanhoe, pretty innocuous given they had just discovered what would become one of the top ten biggest mine in the world.

Ivanhoe’s 2000 drill program on the project consisted of 109 reverse-circulation drill holes,
totalling approximately 9,000 metres. Ivanhoe’s holes were drilled into the four known
mineralized zones (north, central, south and southwest Oyu zones) to depths ranging
between 80 and 130 metres. The program was designed to test a potential high-grade,
supergene copper blanket discovered by BHP during a 23-hole drill program in 1997 and
1998. BHP spent approximately US$2 million on exploration at the property. In addition to
drilling, BHP’s work included detailed geophysical, geochemical and geological mapping.
At this point, the potential size and grade of the mineralized porphyry zones is conceptual in
nature and it is uncertain whether future exploration will result in the discovery of an
economic mineral resource. However, Ivanhoe is encouraged by its initial results which,
viewed in conjunction with those of the BHP drill program, confirm that the four porphyry
zones comprise a mineralized target within an area measuring 3,000 metres by 2,000
metres. A 5,000-metre drill program to help delineate the grade and size of the mineralized
zones is planned to begin in late April. The initial drilling will focus on the South Oyu zone,
where last year’s drilling returned an intersection of 46 metres averaging 1.4% copper and
0.34 grams of gold per tonne. This hole was 300 metres west of BHP’s DDH4, which had
an intersection of 76 metres averaging 1.6% copper and 0.18 grams of gold per tonne in a
hypogene porphyry zone rich in bornite, chalcopyrite and magnetite.
