Reach Resources (ASX:RR1) reports recent mapping at its 100% owned Morrissey Hill Lithium Project in Yinnetharra in Western Australia has identified multiple, previously unrecognised, wide, and strike-extensive pegmatite swarms.
The $41 market capitalisation company says individual pegmatites extend up to 2km in strike length and over 30 metres in width.
The majority are hosted within mafic volcanics (basalts/greenstones) and/or mafic sediments of the Leake Springs Metamorphics Group, the same sequence which hosts Delta Lithium’s neighbouring Malinda Lithium Deposit (ASX:DLI).
Addressing the results, CEO Jeremy says: “Our maiden drill program at Morrissey Hill has been extremely encouraging. Not only have we intersected significant pegmatite widths below surface and stacked down hole to ~400m, the extended time on site has also allowed the team to map some seriously good outcropping pegmatite targets right across the project area.
Most importantly, these pegmatites are hosted within greenstones (mafic volcanics) and/or sediments of the Leake Springs Metamorphic package rather than simply granite as is indicated on the regional scale GSWA map sheets.
These are the same rocks that host the lithium mineralisation at Delta Lithium’s Malinda Project right next door. Our new target areas are a significant development as they potentially extend our strike length at Morrissey Hill to over 10km across all the target areas.
“This 10km does not include the blind pegmatites that we know are on site, based on our intersections during the maiden drill campaign. The future is within Reach“

Combining the potential strike length of the Bonzer Pegmatite Field with these new target areas suggests a total strike length of prospective pegmatites at Morrissey Hill to be in excess of 10km.
However, Reach note this does not include the potential for additional strike from “blind” pegmatites which have been proven to be on site through the recent maiden drill program.
Three of the new target areas, Peggy Sue, Sunset Boulevard, and the Morrissey Hill prospects have all had heritage surveys completed with Peggy Sue and Morrissey Hill cleared for drilling.
The Martin’s Reach prospect will be the subject of further heritage surveys with the Yinggarda people.
Rock chip sampling and an extensive geochemical soil sampling survey, which has proven to be an effective method so far for identifying potentially mineralised pegmatite systems, is now underway across all these areas.
Reach Resources is a critical mineral explorer with a large portfolio of tenements in the resource rich Gascoyne Mineral Field. Recent and historical exploration results have confirmed the presence of Lithium, REE, Niobium and Manganese across the Company’s land holdings.
However, the company is distinct from other pure explorers by also having an Inferred Gold Resource at Payne’s Find and a significant investment in a downstream patented technology that recycles the rare earth elements from the permanent magnets required in electric vehicles, wind turbines, hard disk drives and MRI machines.
