agree with avgjoe - lead and zinc are like nickel but worse
nickel prices rises in 2 of every 5 booms - lead and zinc its like 4-5 yrs between 'its gunna go' excitement and only comes off once every cycle- 15-18 yrs - just not enough rarity generally to really get super tight markets.
if you want to play zinc Terramin is probably your bunny - and that 5 yr stock chat will tell you most of what you need to know about zinc
