Alrighty, then, you asked for it.
First off, if that is part of a gold mine it has to be a hard rock mine - only good reason for such a hoist frame.
That means the track is going to a waste dump (tailings) to get rid of most of the stuff hauled out to make room to look for the quartz veins loaded with gold - the ore that is in need of reduction. So you'll need some tailings - and that can, well, fill your entire table at a highly productive mine with a few years behind it. Or you can just have the tracks run to the edge of the table and postulate the tailings are off the table. Then you'll need a place to reduce the ore, a stamp mill. And perhaps a cyanide plant to be used in that stamp mill. And a tool shop and all the other structures to support a hard rock mine - including the mercury burning, mercury being used in the amalgam to capture the gold.
Or you can go Man From Snowy River - but he didn't have a hoist frame like you do.
I recommend googling up Empire Mine State Park - Grass Valley, California - and see what sort of images they have up and about. You can also try Bodie, California but that might be a bigger stamp mill than you want, by quite a bit.
I live and play in the Mother Lode country of the famous gold rush of 1849 (gold discovery at Sutter's Mill in January of 1848). I worked my way through college, at least part of it, selling gold mining equipment to modern gold hunters back in the day. So, you might say I have some knowledge on the subject, limited as it may be.
But I have seen 80 ounces of gold laid in front of me still mixed in and amongst the quartz it came out of - by some young fool who didn't know he needed a gun in his back pocket carrying something like that around. At the time that was worth an easy $70,000 US - circa 1980. Lots more today but you have to account for inflation!
