Sometimes gold is found on "false bedrock" also known as "hardpan" - very hard layers of clay. In the famous Cariboo area of BC, it was not uncommon to find gold under 60 or 100 feet of sand, gravel, clay, boulders, etc. Gold deep under streams is generally not accessible today. Underground placer mining was popular in the 1800s.

The bar is a river terrace dating back to Pleistocene times. Gold bearing gravel was 6 to 25 feet deep with 5 to 20 feet of overburden. The deposit was about 3,000 feet long and 50 to 500 feet wide. Estimates of the total value place the gold recovered at 550,000 (Lyden 1948; McClernan 1983). BIBLIOGRAPHY

In What Rock Formations Can Gold Be Found? | Sciencing

Gold is most often found in quartz rock. When quartz is found in gold bearings areas, it is possible that gold will be found as well. Quartz may be found as small stones in river beds or in large seams in hillsides. The white color of quartz makes it easy to spot in many environments.

Can gold be found in small quartz rock no more than 5 feet .

Can gold be found in small quartz rock no more than 5 feet .

It's very unlikely. Gold is very dense and never rusts, as the surrounding rock is weathered, tuned to clay and sand, it liberates gold. The gold tends to stick around due to its density, so it can accumulate in highly weathered soils above gold bearing quartz veins. The soils end up with a higher concentration than the original quartz veins.
