Seru Franciso Jobo 20160225 016 smallOn Thursday February 25 we went back to the Christoffel park to continue our search for unknown manganese mines on the side of the Seru Francisco Jobo. This time we didn't park close to the Seru Bientu but close to were the trail to the known manganese mines start. There we went uphill passing the first and second mound of the debris that came from the two mines further up the hill. After a while we reached the lower of the two mines. The entrance to that mine is blocked. During a previous visit Fred went as far as possible through the small opening but behind the opening a lot of debris blocks the entry completely. It would be interesting to investigate this mine by removing the debris so that it can be entered.

A bit further uphill is the entry to the second mine. That entrance also looks small and you have to crawl to enter the mine, but immediately behind the entrance you can stand upright. There is a long, about 100 feet, horizontal shaft; it is pitch black in the mine so we all carried flashlights. The color of the rock at the end of the tunnel is different and that was probably the reason the excavation stopped at this point. The sides of the tunnel have rocks in different colors. If the mining was successful then we wouldn't see manganese. Apparently manganese is gray; inside the mine we found some traces; outside the mine we also found rocks with a thin gray layer on the outside.

These are the two known manganese mines at this location. There is a rumor that there is a tunnel through this mountain to the other side; maybe that is the closed mine; or there are more, yet unknown mines on the slope of this mountain. We decided to search the slope by splitting up, so that we could look for other mines on several levels on the slope. We found two suspicious locations where a lot of small debris and relatively freshly exposed rocks , some with tool marks, suggests blasting; we also found some rocks with traces of manganese. So it seems that at more locations is sought for manganese but apparently these were not promising enough for mining. 

We continued our hike on the slope of the Seru Francisco Jobo till we reached the Kadaster measuring point that we found last time. From there we went back to our cars by gradually descending the slope while going in the direction of the cars.
To our surprise we found a hoe; that means that there was agriculture on the lower slope of this mountain. We also saw several "faha's" in that area; a "faha" is a low dam to regulate the flow of water and to prevent rapid erosion of the ground. That is further proof of agriculture on this slope.

We reached the cars and drove back to the parking lot of Savonet. On our way home most of us made a stop at the 4th of July Snack in Barber for some beers. A good habit to replenish our body fluids.
Next time we will search for (trial) mines on the other slope of the Seru Francisco Jobo; the side facing Jerimi.
