Exhibit 99.1

               Minera Yanacocha Resumes Mining Operations in Peru

      DENVER and LIMA, Peru, Sept. 17 /PRNewswire-FirstCall/ -- Newmont Mining
Corporation (NYSE: NEM) and Compania de Minas Buenaventura (NYSE: BVN) today
announced that Minera Yanacocha has begun resuming normal mining operations at
its mine north of the city of Cajamarca, Peru, after an agreement was reached
between the Government of Peru, representatives from the Cajamarca community and
Minera Yanacocha. The blockade of the access road to the mine ended at
approximately 4:00 p.m. Central Daylight Time today. Minera Yanacocha had scaled
back mining operations earlier in the week as a result of a blockade of the mine
access road.

      The temporary scaling back of mining operations will not impact the
estimated full year 2004 gold production and sales of approximately three
million ounces, on a 100% basis, from Yanacocha.

      Minera Yanacocha worked with all parties to reach consensus to set aside
the exploration drilling permit at the Cerro Quilish gold deposit so that
further hydrological studies can be conducted to assess any future impact Cerro
Quilish may have on the Cajamarca community's water supply.

      Carlos Santa Cruz, Vice President of South American Operations of Newmont,
said, "We are pleased that negotiations led to a peaceful resolution of this
matter. We understand the importance of safeguarding the water supply in the
Cajamarca region."

      Roque Benavides, President and Chief Executive Officer of Buenaventura,
said, "Mining is a vital part of Peru, creating economic opportunities, jobs and
enhancement of the quality of life for local communities. We look forward to
working with the local community in a mutually beneficial and fair manner."

      Newmont, Buenaventura and the Internacional Finance Corporation hold
51.35%, 43.65% and 5%, respectively, in Minera Yanacocha.
