1st experience- drilled in an area repeatedly visited by the JAPANESE. A 300 SQM residential area being offered to buy for 17million by the japanese through a filipino friend.
found a very hard cement at almost 20 feet.destroyed the said hard cement in less than a day. found rusted batteries and wires. found several destroyed metal items. found charcoals, different strata and different sand and soil layers. found several cement layers. hit a very hard cement layer at around 45 feet . pounded the hard cement layer with a 200-300 drillbit for 3 days. on the early morning of the 4th day, the said very hard cement layer can no longer be found. what was most surprising was, the drillbit can be found at around 50 feet already (we measured the metal cable attached to the heavy drill bit every 2 hours) . and everytime we pound the hole, we can hear a very hallow and echoing sound. nobody can give us an idea as to how that happened. everybody in our group agreed that the cement chamber or layer might have transferred to another chamber. i have heard of stories about a sliding concrete chamber before. and we presumed that we might have encountered one. the sad part of the said expedition was we cannot transfer to another area anymore because the said area where we can explore is a house. the owner does not want us to drill anymore. she had enough of our treasure hunting folly that she decided to put a stop to our drilling activity.
You have just found the chamber on this operation. don't be confused about it. You have reached and break in to the chamber. There were chambers which is filled with thick clay and very thick sand. I heard from other areas it is a much as 10ft. you should have purged it with so much water to remove the poison and manually dig it down to investigate. You failed because you stopped. At 50ft the chamber could be very big just like the areas of my friends in luzon.
It is worth reinvestigating by digging another hole beside it. 2-3 feet would be good.
I planned to buy drill rigs that could reach 150ft. It is much easier to drill that way than dug it manual which is more costly. The real problem is the poison. By these bore hole you can purge it as long as you can to clear the site.
Cheers
Guys,
Better find another site if not then someday you found a solution how to continue the project if encounter abnormality mostly if using heavy equipment, If that case then the claim of my friend might be supported and maybe it's true how they come up a solution to their successful recovery.
