Could someone translate me this passage please?

"Daha sonra yollar açıldı ve ben Lefke´ye nişan oldum. 1968 yılında askerliği bıraktım. Kıbrıs Maden Şirketi´nde Mavroni Karadağ dediğimiz bölgede iş aldım. Trene dozer ile bakır madeni yüklerdim. "

My try as learner:

Later, way was opened, and I became engaged to Lefke. Later, the roads opened and I made my way towards Lefke. In 1968 I left military service. I got a job in Kıbrıs Maden company (literally something like "Cyprus Minerals" / "Cyprus Mines"), in region which we call Mavroni Karadağ (literally Mavroni Black-mountain). I was (bull)dozer operator, and I used to load copper ore(*) on to train.

(* - I´m not sure about the "copper ore" here ; literally "bakır madeni" means "copper mine", probably the meaning like "copper mineral" is possible too; I thought that the author meant "copper ore", and I translated it like this, however in Turkish "copper ore" is "bakır cevheri", not "bakır madeni")

Thank you. You helped me a lot. I am trying to locate the places in the text. I found them all, except that Mavroni Karadağ. Is it a mountain?

Karadağ could refer to Montenegro. 

It seems it is in Cyprus, and Karadağ is mentioned in this article on the town of Lefke

If you use GoogleEarth and search for Lefka, Cyprus, you can see remains of old open cut mines and the green tinge of the copper ore just south of the town.

Good luck with your research. 

 Mavrovouni mine near the town of Lefka, were processed at a plant near the town of Xeros on the Mediterranean Sea. The mines and plant were abandoned after 1974, although some processing of ores did occur during the 1980s. After 1994, the Xeros plant was dismantled.

The CMC mining sites are located in the northern foothills and coastal plain of the

Lefke “A” pit mine, adjacent to the town of Lefke and the low grade ore waste

piles in their vicinity;

Sadly, as a result of this copper mining, it looks like there are still environmental problems in this area of Northern Cyprus.

Thank you so much!

"nişan" does mean engaged, but also it means a target or aiming for.

So perhaps it would make more sense to be

"Later, the roads opened and I made my way towards Lefke". As this is a place in Cyprus it seems to fit better

Thank you Marion for noticing this. I saw this word before in the meaning of "engagement" so I didn´t even look into the dictionary to check if it has another meanings (and, while writing my translation, I thought that Lefke must be a woman´s name ). I´ll fix my post now.
