Release: Oropa: High grade mineralisation discovered at Tambang Ubi

Oropa is pleased to announce results from initial limited sampling of historical Dutch underground workings at its Tambang Ubi prospect, North Sumatra, Indonesia

Channel sampling of access drives discovers high grade gold values in association with copper mineralisation:

? Sample 951270: 7.43g/t Au, 0.64% Cu
? Sample 951271: 20.55g/t Au, 0.49% Cu
? Sample 951275: 19.85g/t Au, 0.85% Cu
? Sample 951276: 13.6g/t Au, 1.29% Cu

Tambang Ubi is a garnet - epidote skarn deposit developed on the contact between footwall limestone and hanging wall granodiorite and andesite intrusive bodies. The mining of the deposit by the Dutch Moeara Sipongi Mining Company commenced in the late 1930?s, producing approximately 100,000t of ore, with recovered grades of 6.2g/t Au, 2.77g/t Ag and 0.24% Cu. Mining ceased in 1939 due to the commencement of WW2.

Historical sections and mine plans were sourced and digitized by Oropa in conjunction with the completion of access negotiations with local miners still exploiting gold / copper mineralisation in the area. A number of access drives were refurbished to allow or safe entry.

Modelling clearly shows the areas actively stoped during the last year of Dutch mining operations and that stoping did not continue far below the current water table. Historical records indicate that mineralisation remains open at depth in both a down-dip and down plunge direction.

Oropa has completed programmes of gridding, mapping and a ground magnetic survey over the Tambang Ubi area in preparation for drilling this coming quarter. (end of release)
