Police confirmed that the suspected contraband which washed up on beaches near Mossel Bay over the festive season is uncut cocaine worth about R100-million rand.
Although police are still investigating the matter, which has been dubbed "white Christmas" on the Garden Route, Southern Cape police spokesman Captain Malcolm Pojie said forensic tests revealed that the substance was in fact pure cocaine.
"The incidents are still being investigated by the organised crime unit of the Hawks and no arrests have been made. The latest however is the fact that we received the test results back which confirmed our suspicions that it is cocaine," Pojie said.
Four batches of the drugs were found along beaches in the Mossel Bay area between Christmas last year and New Year's.
The final haul contained a bag with 25 "bricks" of cocaine attached to a blue drum floating in the ocean and was spotted by a holidaymaker on New Year's day.
The day before this discovery was made, a resident spotted another bag with 25 bricks of the substance, while a third bag was spotted by a swimmer.
The fourth amount was found in the water near Hartenbos beach on Christmas day, also containing 25 packets.
