The Jezero Delta Simulant (JEZ-1) was made to simulate anticipated materials in the Jezero Crater deltas that will be investigated by the NASA Mars 2020 Perseverance rover. Exolith Lab is able to simulate this from orbital data of the Jezero Crater and was quintessential for the preparation of the Perseverance Landing. The Perseverance Rover’s main mission is to seek signs of ancient life and collect samples of regolith to possibly return to Earth. This mission will bolster the understanding we have of Martian Regolith, and further propel ISRU Research around the world, of which Exolith Lab will be a leader.
The simulant is a mixture of MGS-1 mineralogy with smectite clay, Mg-carbonate, and additional olivine that have all been detected from orbital remote sensing in the Jezero delta deposits.
The state of lithificaiton, mineralogy, and grain size distribution are likely variable throughout the Jezero deltas; JEZ-1 represents unconsolidated material, but can be compacted under various pressures to form a more cohesive solid.

Note that bulk density is not an inherent property and depends on the level of compaction.
