Piedmont Mining Signs Agreement With Miranda on PPM Gold Project, Nevada

Reno, NV – April 23, 2007 - Piedmont Mining Company, Inc. (OTC BB: PIED) today announced that it has signed an ‘Exploration Agreement With Option To Form Joint Venture’with Miranda US, Inc., a wholly-owned subsidiary of Miranda Gold Corp. (TSX-V: MAD), on their PPM gold property in Humboldt County, Nevada. This property is located at the north end of the Battle Mountain-Eureka gold trend on the west flank of the Hot Springs Range and just north of the town of Winnemucca. It is about 10 miles north of Piedmont’s Dutch Flat gold project and about 12 miles northwest of the Twin Creeks, Turquoise Ridge and Pinson gold deposits where past production and current resources now exceed 23 million ounces. The PPM property now consists of 116 unpatented claims.

The property overlies a northeast striking fault system that intersects biogeochemical gold-in-sagebrush anomalies near the margin of an inferred buried intrusive and adjacent to a sediment-hosted mercury district. Such mercury occurrences are frequently closely associated with sediment-hosted gold systems in Nevada.

Under the terms of the agreement, Piedmont must expend at least $175,000 in exploration work during the first year of the agreement, $200,000 during the second year, $300,000 during the third year, $425,000 during the fourth year and $650,000 during the fifth year of the agreement. Upon completing the total $1,750,000 work expenditure requirement, Piedmont will have earned a 55% interest in the property and the project. At that point, Piedmont and Miranda would enter into a joint venture with Piedmont being the operator. After the first year of the agreement, Piedmont may terminate the agreement at any time on 30 days written notice. Piedmont must pay all claims maintenance fees, which will be creditable against the work commitment expenditure requirement, and must pay Miranda $25,000 within 30 days of signing the agreement.
