If a Muslim’s net annual savings fall below the Nisab, he or she is exempt from paying Zakat. If you only have gold as an asset, then the Nisab measure for gold must be used.
However, if you have a mixture of assets, using the Nisab value for silver is advisable according to some scholars as it is more beneficial to the recipients.
Although other scholars maintain that gold should be used regardless.
