The golden mining top gives players a 1% boost to Miningexperience gained. It is a reward from the Liquid gold nymphs in the Lava Flow Mine. It is the last of the five pieces of the golden mining suit that the nymph gives. The top, when worn with the rest of the Golden mining suit, has the mining effect of whichever Varrock armour the player owns, as well as contributing to the total 5% experience boost of the full suit. The effect is the same if the Varrock armour is worn with the set instead of the top, except that the Varrock armour has some defensive stats, weighs 9 kg less, permits smithing of two bars at the same time and can be easily regained if lost. This does not account for mining clay. With the golden mining top, no double pieces of clay can be obtained and wearing the Varrock armour does not provide the full 6% experience boost.
Before an update on 25 May2011, it was more beneficial to wear Varrock armour instead of the Golden mining top with the rest of the set because Varrock armour can double the ore yield, thus doubling the experience gained. This was patched, so now the Golden mining top has the effects of Varrock armour along with the 5% bonus if worn with the rest of the Golden mining set.
