Port Dizon in Subic Bay?
How many of our sailors knew that there was a Dizon Mine and a Port Dizon in our Subic Bay neighborhood? So, I collected some pictures of both establishments and present them here.

Dizon Copper-Silver Mines, Inc.
Company Description
Dizon Copper-Silver Mines, Inc. (DIZ) was incorporated on August 18, 1966 to acquire, purchase, lease, hold, work and operate mines, mining claims, grounds, or lodes in the Philippines or in foreign countries. DIZ previously had 57 mineral claims in Barangay Buhawen, San Marcelino, Zambales with a total area of 513 hectares, which were developed and operated by Benguet Corporation (BC) for 20 years under the operating contract entered into by and between DIZ and BC on September 6, 1975.
After more than 20 years of occupation, exploration, and operation of mineral claims in San Marcelino, Zambales, BC turned over its operating rights to DIZ by virtue of a Memorandum of Agreement dated November 25, 1997 following the closure of mining operations. Mining operations stopped because of massive landslides in the mining pit caused by heavy rains which destroyed mine infrastructures, accompanied by a sudden fall of metal prices in the world market. This made the rehabilitation of the mine facility and resumption of operations non-viable.
With the suspension of its mining operations, the Company’s present activities are confined to the care and maintenance of the mine site and the mining properties therein. DIZ’s port facility, Port Dizon, located in Subic, Zambales may still be used as loading facility for ore and aggregates should the company resume mining operations. DIZ has continued to maintain the major dam structures to prevent spillage of the mine tailings.
On June 15, 2016, the Securities and Exchange Commission approved the Amendment to Article No. 4 of the Articles of Incorporation to extend the life of the corporation for another Fifty 50 years from August 17, 2016 to August 16, 2066.

On the west (right side) side of the river is/was the Dizon Port and on the east (left side) is Baloy Long Beach, part of Barrio Barretto (my home) which is part of Olongapo City. Directly at the left side of the Matain River Mouth, at Baloy Beach, is a new hotel/resort being constructed.
