Morella Corporation Ltd (ASX:1MC) is a lithium-focused explorer whose Mac Well Project in the Pilbara, Western Australia, is held in a joint venture with Elevra Lithium Limited (ASX: ELV), with Morella at 51% and Elevra at 49%. On 19 October 2026, the shares touched a 52-week low during the Trading session and closed at $0.022, down 8.33%. In an ASX announcement dated 30 September 2026, Morella reported rock chip and soil sampling results that identified rubidium and lithium targets at Mac Well.

Rock chip results

The company collected 27 rock chip samples from pegmatite outcrops, composited from several fragments at each site, and sent them to ALS in Perth for a four-acid digest with ICP-AES and ICP-MS finish. Twenty-one samples returned more than 0.1% Rb₂O, and eight returned more than 0.3% Rb₂O, five of which also exceeded 0.1% Li₂O.

The highest result, sample M000969, returned 0.78% Rb₂O and 0.71% Li₂O. Other notable results include 0.48% Rb₂O with 0.26% Li₂O in M000971 and 0.40% Rb₂O with 0.05% Li₂O in M000962. Most lithium values were lower, with several below 0.1% Li₂O.

Soil sampling

A total of 296 soil samples were taken from 30 centimetre pits within exploration licence E45/5904, sieved to minus 2 millimetres and assayed in full for a lithium and rare earth suite. Targets were selected from aeromagnetic surveys and satellite imagery. The results define several areas of geochemical anomalism for follow-up. Mac Well lies about 2.5 km north-east of Wildcat Resources’ Bolt Cutter Project.

Rubidium and next steps

The announcement describes rubidium as a rare alkali metal found in highly fractionated lithium-caesium-tantalum pegmatites and used in advanced electronics, specialty glass, fibre optics and atomic clocks. It notes that rubidium is on the United States’ 2025 Critical Minerals List and that Supply is limited. Mac Well adds a rubidium-bearing system to the Morella-Elevra portfolio alongside Mt Edon.

Future work comprises additional surface sampling and geological mapping over the new targets and, depending on those results, the design of a maiden drilling program to test priority pegmatite targets.

Several other rock chip samples returned notable rubidium values, including 0.32% Rb₂O at M000946, 0.35% at M000949, 0.32% at M000951, 0.38% at M000967 and 0.30% at M000964, which also returned 0.19% Li₂O. The announcement presents these in a table of notable results with sample coordinates, and the samples are spread across several areas of the project, which the company says identify places for follow-up mapping.

The Mac Well Project forms part of the Morella-Elevra joint venture portfolio, which the announcement says also includes the Mt Edon rubidium system. The company states that the project is at an early stage and that the combination of rock chip results and soil anomalies provides a basis for follow-up work and, ultimately, drill targeting. The lithium-caesium-tantalum potential of the area is the main theme of the planned evaluation.

Sector backdrop

Broader market context for the 19 October 2026 session: S&P/ASX 200 (ASX: XJO) stood at 8,845.70 at 4:25 pm (GMT+11) on 19 October 2026, up 0.44%, or 39.00 points, for the day. The sector map showed a split result. Energy rose 2.16%, Industrials 0.93%, Financials 0.85%, Utilities 0.38% and Consumer Staples 0.25% on the day, while Information Technology fell 1.35%, A-REIT 0.34%, Consumer Discretionary 0.18%, Telecommunication Services 0.16% and Health Care 0.13%.

Risks shareholders should weigh

The results are surface samples from an early-stage project. Rock chips from outcrop do not show how deep or continuous mineralisation is, and the announcement states there has been no drilling. Lithium grades were mostly modest compared with the rubidium values.

The project is a joint venture, so decisions and costs are shared with Elevra, and a maiden drilling program is conditional on follow-up work. The company has not stated how further exploration will be funded.

What’s next

The company will carry out more mapping and sampling at Mac Well, assess the newly identified anomalies and decide whether to design a maiden drilling program.
