   The entrance is in the middle of thorns and jungle at the roadside. An open entrance with an angle-of-rest slope down to a narrow rift and a calcite blockage. There was a nursery of shrews living at the top of the entrance slope. This site was written-off after digging under flowstone in November 2015. The draught came in from a small inlet passage on the right and further prospects looked poor.

   In August 2016, the site was revisited and a crawl at the bottom was seen with boulders that will dig.

   At the end of January 2018, a passage (Up & Running) entered at a c+2 climb to the south of Mulu Junction in Cueva-Cuvío del Llanío ended after about 50m at a strongly draughting, easily dug crawl. This may be only about 30m from the end of Shrewd Find. The passage leading to the dig can be seen on a Llanío video at 2:03.
