Junior Palmer Resources (PMD-V) is targeting widespread, sediment-hosted, stratiform copper mineralization in Vietnam’s northern province of Bac Giang.
The company has secured three exploration licences covering a total of 203.7 sq. km in the Cam Son, Lang Cha and Bien Dong areas.
Reconnaissance exploration in 1995 identified copper mineralization in both stratigraphically and structurally controlled settings. The mineralization is confined to greenish sandstone and siltstone beds within a thick sequence of red sediments. The primary copper sulphide is chalcocite, with minor bornite and rare chalcopyrite. The mineralization occurs in the matrix of the host sediments and as a replacement of diagenetic pyrite and organic material.
Palmer says earlier French colonial and Vietnamese exploration parties failed to recognize the extent and grade of the copper mineralization because it is extensively leached in surface exposures.
Chip sampling has returned values ranging from 0.97% copper and 11 grams silver per tonne in a surface exposure to 6.7% copper and 53 grams silver from an old underground exploration adit.
In February, the company will begin geological mapping, geophysics, trenching and sampling. Depending on the results, drill targets will be selected later in the year.
Palmer says geological analogues for the Vietnamese copper occurrences include the Zambian copper belt.
Palmer’s portfolio includes holdings in the Philippines, Indonesia and British Columbia.
