Multiple stacked pegmatites within Reach

Reach Resources (ASX:RR1) has intersected multiple stacked pegmatites over ‘substantial’ widths at the Bonzer prospect within its 100% owned Morrissey Hill Lithium Project in Yinnetharra, Western Australia.  

The $44.17 million market capitalisation company says importantly, target pegmatite units have been intersected in every hole drilled, with individual drill intercepts ranging from 1m to 30m in length.

Consistent with Delta Lithium’s Malinda Lithium Project located immediately to the east of Morrissey Hill, drilling at the Bonzer prospect has confirmed the presence of multiple stacked pegmatites1 to depths of ~400m (down hole).

Additionally, Reach Resources notes at least one of the larger pegmatites intersected at depth appears to be ‘blind’ (no pegmatite or anomalous assays present at surface), which opens up a potential new target for future drill testing.

Addressing the results, Jeremy Bower CEO says: “The extensive soil sampling campaign conducted at Morrissey Hill prior to the commencement of drilling is paying dividends. We are very happy to confirm that the  outcropping pegmatites are being repeated with substantial widths  at depth within the right host rocks.   

The future is within Reach. Exciting times ahead

In addition, diamond drill core is confirming blind pegmatites exist in the area, which is extremely promising and consistent with the geology at neighbouring Delta Lithium’s (ASX: DLI) Malinda Lithium Project.

We’re pushing hard to gather as much information as we can prior to the commencement of Yinnetharra Station’s annual cattle mustering program which will see our Phase 1 drilling campaign take a break on the 10th of September. Our geological team has worked incredibly hard, and we are extremely happy with what we are seeing.

We will get some extra metres drilled to what was previously planned before mustering commences and we head back to Perth. We eagerly await assays in early to mid‐October. The future is within Reach. Exciting times ahead.”

Phase one RC drilling has been concluded with 21 holes drilled for a total of 2,656m including pre‐collars for diamond holes. Diamond drilling continues with four (4) holes complete to date for 1072m.

Reach reports that drilling has confirmed the presence of multiple pegmatites in each hole with individual intercepts ranging from 1m to more than 30m in length. The pegmatites occur within a variety of host rock types including granites, and sediments/mafic units interpreted as being a part of the Leake Springs Metamorphics Group.

The company says importantly these are the same rocks which host the Malinda Lithium Deposit pegmatites located 8km along strike to the east of Morrissey Hill.

The company’s maiden phase one drilling campaign has been focussed on a 500m long section of the west‐ central portion of the Bonzer pegmatite field which extends for over 2km’s in strike length. The potential of the area to host significant lithium mineralisation was highlighted by the results from earlier surface sampling conducted by RR1, which returned soil values in excess of 750ppm Li20 and rock chip values of up to 2.3% Li2O, 4295ppm caesium and 705.8ppm tantalum.
