From OP's article:

Earlier, reports emerged that Russia’s central bank has reduced its gold holdings for a sixth consecutive month, selling 43.5 metric tons since January in the largest six-month drawdown recorded in at least a quarter-century.

The sales came as Russia’s federal budget deficit approached 6 trillion rubles (more than $76 billion) during the first half of the year.

So we know how much gold was sold, but I couldn't tell you how much is left.
