Boab Metals Limited Reports the Success of the Sorby Hills Phase VII Drilling Program

Boab Metals Limited Reports the Success of the Sorby Hills Phase VII Drilling Program

Boab Metals Limited (ASX: BML) (“Boab” or the “Company”) announced the successful completion of the Phase VII drilling program at its 75% owned Sorby Hills Lead-Silver-Zinc Project, located in the Kimberly Region, Western Australia. The drilling program at the Keep Seismic Target resulted in the potential discovery of a new zone of mineralisation over a 15m interval from 242m, including levels of massive sphalerite (ZnS). 

Key Highlights

  • All program goals were achieved within the budget, with the drilling of 2,634 metres across 22 drill holes, representing a 24% increase in drilled metres. The Company has also tested one new target.
  • The “Keep Seismic Target” drilling produced an intercept of visible mineralisation over a metre interval from a depth of 242 metres, including sections of massive sphalerite (ZnS).
  • Assay results are anticipated for late Q3 or early Q4 2023.

On this remarkable achievement, the Managing Director and CEO, Mr Simon Noon, said:

We are pleased to report the successful completion of our 2023 drilling campaign. Efficient drilling progress has allowed us to complete additional drill holes within the original budget, including three drill holes to test extensions to mineralisation north of Norton and Beta deposits, as well as the testing of the conceptual “Keep Seismic Target”. We are very excited to report that the drill hole at the Keep Seismic Target has predominantly intersected zinc-sulphide mineralisation between 242m and 257m. With the target’s conceptual nature and location at a depth where no mineralisation has been discovered, this is a great success. The location of the drill hole sits around 2km from the closest defined deposit at Sorby Hills.

Mineralisation continuity was also confirmed by the step-out drill holes at Norton and Beta. In conjunction with our 2023 drill program, Boab continues to advance toward a final investment decision on the Sorby Hills Project with preferred EPC contractor GRES firming up Front End Engineering & Design work, and discussions with financiers are ongoing.”

Background to Phase VII drilling program

Mineral Resource

The Sorby Hills Project reserve base was to be increased through additional metallurgical testwork, extensional drilling, and in-fill drilling. This objective was the focal point of Boab Metals’ proposed Phase VII drilling program, encompassing 19 diamond drill holes spanning approximately 2,000m.

The efficient and economical progress allowed the drilling of additional holes. As part of the program three additional holes were drilled: one at Norton North, 50m north of SHSD_164, in the region of scattered historic drilling; one at Beta to investigate the continuity of mineralisation; and one deep drill hole at the south of the present resource area.

Phase VII Drilling Program 

The drilling program concluded with the completion of 22 drill holes totalling 2,634m, which is also 24% more metres than originally planned. Out of the total program, 1,200m across nine holes were drilled for resource/reserve expansion and exploratory goals, and 1,433m across 13 holes were drilled for metallurgical purposes. The use of sonic drilling technologies to penetrate the unconsolidated cover rocks during the drilling program has resulted in productivity gains.

The Keep Seismic Target

As indicated in July 2022, the Keep Seismic Target is a conceptual drill target that was developed using the interpretation of historical seismic data from petroleum development over the Burt Range Sub-Basin. As part of the Phase VII drilling program, Boab Metals successfully dug a 306.5m deep drill hole into the Keep Seismic Target. The drill hole SHSD_185 encountered the lower part of the Knox Formation around 224.6m. It concluded at a depth of 306.5m within extensive Sorby Dolomite, following the traversal of two mineralisation zones (upper interval of mineralisation and lower mineralisation interval).

The upper interval of mineralisation consists of disseminated and thin bands of massive sulphide-filled veins containing galena (PbS), marcasite (FeS), and sphalerite (ZnS). In the lower mineralisation interval – the principal target – there are intermittent sections of massive colloform sulphides dominated by sphalerite, along with disseminated coarse crystalline galena. The lowest massive sphalerite bed is located at a depth of 266.2m.

The Company believes that the initial findings at the “Keep Seismic Target” mark a substantial achievement in their exploration efforts. These results validate the concept and underscore the Burt Range Basin’s capacity to contain a notably more significant base metal mineralisation.

In this capacity, he developed joint ventures and strategic partnerships with mid- and top-tier miners.

Since taking the reins at Boab Metals in 2013, Mr Simon Noon has been in charge of project evaluation and exploration across Australia and South America. Notably, he oversaw the large purchase of Sorby Hills in Western Australia in 2018. Under Mr Simon Noon’s direction, Sorby Hills has seen a 50% rise in the size of its mineral resource and the completion of a high-quality PFS and a Definitive Feasibility Study highlighting the Project’s strong economics and low risk.

Investor’s outlook

  • During the recent quarter, Boab Metals Limited achieved notable progress at their flagship Sorby Hills Lead-Silver-Zinc Project, bringing them closer to deciding mine. The Company’s commitment to ethical exploration and development aligns with the rising demand for refined lead, silver, and zinc.
  • The Program has accomplished all its objectives, exceeding expectations by drilling 24% more metres than initially planned, all within the allocated budget.
  • The drilling of the “Keep Seismic Target” area yielded an intercept displaying visible mineralisation. This mineralisation included sections with substantial sphalerite, a highly encouraging sign of potential economic deposits.
  • The assay results, expected to be unveiled in late Q3 or early Q4 of 2023, hold great promise.
