1 00:00:02,586 --> 00:00:05,047 ‐ ..."Lost Gold of World War II..." 2 00:00:05,047 --> 00:00:06,798 ‐ John: All the signs and symbols were pointing 3 00:00:06,798 --> 00:00:08,258 last year to the waterfall, 4 00:00:08,258 --> 00:00:09,885 and I believe there was a treasure under there. 5 00:00:09,885 --> 00:00:13,096 The satellite made multiple hits right on the waterfall. 6 00:00:13,096 --> 00:00:15,307 ‐ We think we've got either a tunnel 7 00:00:15,307 --> 00:00:17,267 or some type of void space. 8 00:00:17,267 --> 00:00:19,520 ‐ Is that a blade right there? 9 00:00:19,520 --> 00:00:22,231 ‐ Could mean that Americans were here putting this in. 10 00:00:45,379 --> 00:00:46,713 ‐ Keep it coming. 11 00:00:47,965 --> 00:00:49,174 ‐ Announcer: John Casey, 12 00:00:49,174 --> 00:00:50,551 a construction contractor 13 00:00:50,551 --> 00:00:51,551 from the U. S., 14 00:00:51,551 --> 00:00:53,220 is back in the Philippines 15 00:00:53,220 --> 00:00:54,346 with a new team... 16 00:00:56,431 --> 00:00:59,226 continuing his search for Yamashita's gold. 17 00:00:59,226 --> 00:01:01,186 ‐ We're gonna find a way to get to this treasure. 18 00:01:04,731 --> 00:01:06,942 ‐ Like many others, John believes 19 00:01:06,942 --> 00:01:09,319 Japanese general Tomoyuki Yamashita 20 00:01:09,319 --> 00:01:11,822 took billions of dollars in treasure 21 00:01:11,822 --> 00:01:14,283 looted by Japan during World War II 22 00:01:14,283 --> 00:01:16,743 and buried in the Philippines, 23 00:01:16,743 --> 00:01:20,163 including somewhere in this mountain. 24 00:01:23,917 --> 00:01:26,086 According to an eyewitness, 25 00:01:26,086 --> 00:01:29,089 mysterious wooden crates were hauled up this mountain 26 00:01:29,089 --> 00:01:30,716 by prisoners of war 27 00:01:30,716 --> 00:01:34,553 and buried in tunnels, which were then destroyed. 28 00:01:36,471 --> 00:01:37,222 ‐ ...boom. 29 00:01:38,682 --> 00:01:40,601 ‐ Based on that account, 30 00:01:40,601 --> 00:01:43,437 John followed a series of mysterious symbols 31 00:01:43,437 --> 00:01:45,022 to three promising sites‐‐ 32 00:01:46,231 --> 00:01:47,899 a waterfall... 33 00:01:47,899 --> 00:01:49,651 ‐ This waterfall's hiding something. 34 00:01:49,651 --> 00:01:52,487 ‐ ...a crater known as Breach 6... 35 00:01:52,487 --> 00:01:55,115 ‐ I've never seen anything like this. 36 00:01:55,115 --> 00:01:58,160 ‐ ...and a camouflaged tunnel they uncovered last year. 37 00:01:58,160 --> 00:01:59,494 ‐ We are in the mountain, boys. 38 00:01:59,494 --> 00:02:02,122 ‐ Can they finally discover the... 39 00:02:13,592 --> 00:02:17,220 In a remote area of the Philippine jungle, 40 00:02:17,220 --> 00:02:20,390 John continues his long obsession 41 00:02:20,390 --> 00:02:21,808 with the waterfall. 42 00:02:21,808 --> 00:02:23,727 He believes these strange carvings 43 00:02:23,727 --> 00:02:25,979 could provide clues to treasure 44 00:02:25,979 --> 00:02:28,065 hidden under orders from the Golden Lily, 45 00:02:28,065 --> 00:02:30,734 a group of Japanese power brokers 46 00:02:30,734 --> 00:02:33,153 allegedly directing General Yamashita. 47 00:02:34,821 --> 00:02:38,367 ‐ I betcha that was a marker to our tunnel. 48 00:02:38,367 --> 00:02:39,951 Right on top of this big rock! 49 00:02:39,951 --> 00:02:42,704 You see that's definitely a box marker on that rock! 50 00:02:42,704 --> 00:02:45,540 ‐ Deeply rooted in Japanese culture, 51 00:02:45,540 --> 00:02:49,378 waterfalls are believed to garner power and protection. 52 00:02:49,378 --> 00:02:54,049 For centuries, Shinto priests buried valuables in waterfalls 53 00:02:54,049 --> 00:02:57,636 for safekeeping, especially during wartime. 54 00:02:57,636 --> 00:03:01,556 It's thought the Golden Lily followed this tradition. 55 00:03:01,556 --> 00:03:05,435 And last year, John tried to find a way in. 56 00:03:05,435 --> 00:03:07,187 ‐ We're really having a hard time 57 00:03:07,187 --> 00:03:09,272 digging around this big rock at the waterfall. 58 00:03:09,272 --> 00:03:11,608 ‐ But was defeated. 59 00:03:11,608 --> 00:03:13,527 ‐ We're gonna be here forever. 60 00:03:13,527 --> 00:03:18,323 ‐ A recent Nuclear Magnetic Resonance, or NMR scan, 61 00:03:18,323 --> 00:03:21,785 suggests John's hunch could be right. 62 00:03:21,785 --> 00:03:24,371 It shows a massive metal deposit 63 00:03:24,371 --> 00:03:27,541 and a possible tunnel deep beneath the waterfall. 64 00:03:27,541 --> 00:03:29,751 ‐ It's like about 300 feet down. 65 00:03:29,751 --> 00:03:31,878 ‐ If the Japanese are burying big treasures 66 00:03:31,878 --> 00:03:33,296 like the one that's up there, 67 00:03:33,296 --> 00:03:34,548 it could be that deep. 68 00:03:35,882 --> 00:03:37,717 NMR's saying we got a target here. 69 00:03:37,717 --> 00:03:40,095 We got all these signs and symbols 70 00:03:40,095 --> 00:03:41,430 that have been leading me to this location, 71 00:03:41,430 --> 00:03:42,973 saying there's something here. 72 00:03:45,058 --> 00:03:47,018 ‐ But John has a problem. 73 00:03:48,770 --> 00:03:51,231 ‐ 300 feet's a long way down. 74 00:03:51,231 --> 00:03:53,316 It's one thing to know where something is. 75 00:03:53,316 --> 00:03:55,819 Doesn't mean you can always get it out. 76 00:03:55,819 --> 00:04:01,116 ‐ Standing in his way is 300 feet of solid diorite, 77 00:04:01,116 --> 00:04:03,785 one of the hardest rocks on earth. 78 00:04:03,785 --> 00:04:05,912 ‐ I mean, the Japanese were specialists 79 00:04:05,912 --> 00:04:08,540 at tunneling into hard rock. 80 00:04:08,540 --> 00:04:10,917 ‐ But drilling through rock this hard 81 00:04:10,917 --> 00:04:14,463 requires a specialized 40‐ton machine 82 00:04:14,463 --> 00:04:17,090 impossible to bring to this remote site. 83 00:04:17,090 --> 00:04:19,676 ‐ There's no way I can even get equipment up here 84 00:04:19,676 --> 00:04:21,178 without a helicopter to bring it in. 85 00:04:23,638 --> 00:04:25,724 ‐ This kind of drilling process 86 00:04:25,724 --> 00:04:28,977 also produces highly toxic waste water. 87 00:04:28,977 --> 00:04:31,188 ‐ Even if I could bring it in, 88 00:04:31,188 --> 00:04:33,356 the whole water supply from the town below 89 00:04:33,356 --> 00:04:35,525 comes from our waterfall. 90 00:04:35,525 --> 00:04:38,320 We're not gonna be screwing with the town's water supply. 91 00:04:38,320 --> 00:04:41,823 ‐ These obstacles make drilling the waterfall impossible 92 00:04:41,823 --> 00:04:44,284 for now. 93 00:04:44,284 --> 00:04:46,953 ‐ I got to figure out a way to get in there. 94 00:04:48,830 --> 00:04:50,373 How am I going to get it out? 95 00:04:56,922 --> 00:04:59,549 ‐ As John looks for a way into the waterfall... 96 00:05:01,343 --> 00:05:04,721 Miners Levi and Geo are battling Mother Nature 97 00:05:04,721 --> 00:05:06,431 at the tunnel site. 98 00:05:06,431 --> 00:05:08,183 ‐ It's crucial that we get in there 99 00:05:08,183 --> 00:05:09,434 and see where this thing goes. 100 00:05:09,434 --> 00:05:10,811 It could lead to another tunnel. 101 00:05:10,811 --> 00:05:12,229 It could lead direct to the treasure. 102 00:05:13,814 --> 00:05:16,399 ‐ This mysterious tunnel was discovered last year. 103 00:05:16,399 --> 00:05:18,276 ‐ We're in the mountain, boys. 104 00:05:18,276 --> 00:05:19,736 ‐ It's believed to be connected 105 00:05:19,736 --> 00:05:21,822 to an elaborate network of tunnels 106 00:05:21,822 --> 00:05:24,616 running deep into the mountain. 107 00:05:24,616 --> 00:05:28,245 Recently, John and the team discovered a knife here. 108 00:05:28,245 --> 00:05:29,871 ‐ Aw, man, look at that. 109 00:05:29,871 --> 00:05:31,581 ‐ Looks like a handle to a knife. 110 00:05:31,581 --> 00:05:34,501 ‐ The find raises new questions‐‐ 111 00:05:34,501 --> 00:05:36,586 who else has been here 112 00:05:36,586 --> 00:05:39,172 and what awaits them inside. 113 00:05:39,172 --> 00:05:40,966 ‐ After finding that knife, 114 00:05:40,966 --> 00:05:42,551 seeing that there's still artifacts in here, 115 00:05:42,551 --> 00:05:43,844 this thing hasn't been picked dry, 116 00:05:45,303 --> 00:05:46,263 we definitely do not want to lose this at this point. 117 00:05:47,889 --> 00:05:50,350 ‐ Geo: Man, that rain is not letting up. 118 00:05:50,350 --> 00:05:51,893 ‐ We're dealing with a lot of clay and mud, 119 00:05:51,893 --> 00:05:53,311 and now this rain we're getting, 120 00:05:53,311 --> 00:05:54,688 it could cause a landslide 121 00:05:54,688 --> 00:05:55,772 and we could lose everything we've worked for. 122 00:05:57,732 --> 00:06:01,236 ‐ They plan to use one of the team's two excavators 123 00:06:01,236 --> 00:06:04,281 to install steel support beams at the tunnel's entrance 124 00:06:04,281 --> 00:06:06,825 before the storm triggers another collapse. 125 00:06:06,825 --> 00:06:08,451 But the muddy conditions 126 00:06:08,451 --> 00:06:10,871 are putting that plan in jeopardy. 127 00:06:12,455 --> 00:06:14,082 ‐ I'd hang as close to that bank as you can. 128 00:06:14,082 --> 00:06:15,417 It's messed up bad. 129 00:06:15,417 --> 00:06:16,793 ‐ Get over there, it's just frickin' sliding. 130 00:06:22,507 --> 00:06:23,925 ‐ Come on, baby. 131 00:06:23,925 --> 00:06:25,218 ‐ Come on. 132 00:06:25,218 --> 00:06:26,344 Keep pinching. 133 00:06:35,604 --> 00:06:39,024 ‐ With the excavator unable to reach the site 134 00:06:39,024 --> 00:06:40,191 and the threat of collapse
