I'm afraid I'm going to struggle to remain on theme for this log. I am only familiar with the topic due to the few propaganda messages still played on our monitors from time to time. The presence of Slave Mines is barely touched upon by Hawkins and McCamley, so I'm upset I missed the chance of attending Dr Jacksons lecture. Still, upon hearing of this bit of local history, no matter how hushed up it was, I had to know more. And so, after our recent success in tracking down Der Fahrers belongings I was invited to join habitual abanazar FTFers, pljg and bradlad. The homework was done and a date was set. I arrived at our rendezvous well before pljg and bradlad as they were held up by a crashed ship near fiveways junction.
We kitted up and headed through the first gate (with my improvised key - I seem to have temporarily mislaid my other) - The trickiest navigation was first and it was only here that we struggled but soon pljg discovered what was required resting by the skull of a poor slaves companion. Further clues as to the Goa'uld's use of the mine and the local populace we discovered until we reached the penultimate stage. Here it took quite a while to obtain the information we needed - firstly we needed to 'La Cucaracha the pig' - and then we forgot to use the most recently obtained information. But soon we knew what we had to do. 
We headed onwards, deeper and further than ever before. We discovered what must've been a temple, more likely Goa'uld rather than slave. We found ancient portals, no doubt leading to more nefarious locations of the slave mine. We braved poisonous gases. And eventually we reached our goal. Treasure was plundered (thanks very much) It was then time to seek the exit. This was achieved at near light speed and there was only a brief worry when my key initially failed to free us. We exited the mine at 1:20 am euphoric and tired. 
Another classic from the abanazar stable. Thank you so much for all the hard work that went into it and I hope we left things in such a way that others can follow. 
Post script: I particularly enjoyed one aspect of the puzzle and had a giggle at the idea of someone happening by whilst it was being created.
