Tivan Limited (ASX:TVN) has commenced its maiden diamond drilling program at the Scorpion Prospect, part of the Baucau Project in the Democratic Republic of Timor-Leste, following the grant of relevant approvals, the company disclosed on 9 November 2026.

Key Points

  • Drilling contractor PT Indodrill Indonesia has mobilised an ID500 man-portable diamond drill rig to the Scorpion Prospect within concession MEI-2023-CA-ZB003.
  • The program comprises up to six stratigraphic diamond drill holes for up to 1,500 metres within a 2.3 km² area.
  • The Scorpion Prospect hosts a polymetallic geochemical anomaly approximately 1,000m by 800m in extent, identified from 70 rock chip samples.
  • The drilling program is anticipated to take approximately two months to complete, with assay results expected early in Q1 2027.
  • Approximately 40 people from villages in Ossoala will be employed to assist in executing the drilling campaign.

Scorpion Prospect Drilling Program Details

The maiden drilling program targets a priority copper-gold area at the Scorpion Prospect, which hosts a significant polymetallic geochemical anomaly extending approximately 1,000m by 800m, identified through geological mapping, surface geochemical sampling and geophysical surveys. The program will provide the first subsurface geological information to support evaluation of the prospect's mineralisation potential. Diamond drill core recovered during the program will be transported to Tivan's exploration compound in Baucau, known as Casa Tivan, for geological logging, photography, core cutting and sampling before being exported to Intertek's laboratory in Jakarta, Indonesia, for geochemical analysis.

Equipment Selection and Drilling Methodology

Tivan appointed PT Indodrill Indonesia, part of the Singapore-headquartered Global Drilling and Exploration Group, to conduct the program using an ID500 man-portable diamond drill rig. The company stated the rig was selected due to the challenging topography, environmental considerations and technical objectives of the program. The ID500 can be transported in modular components and assembled at individual drill locations, reducing vegetation clearance, ground disturbance and site preparation requirements. The company also noted the rig's smaller operational footprint and anticipated lower noise emissions compared with conventional large-scale reverse circulation equipment. Tivan stated it expects the ID500 rig will also be preferred for its maiden drilling program at the Turiscai Project, tentatively scheduled for mid-2027.

Local Participation and Community Engagement

According to the filing, Tivan's exploration programs in Timor-Leste are designed to prioritise local participation and deliver lasting benefits to communities within relevant project areas. Approximately 40 people from villages in Ossoala will be employed to assist in executing the drilling campaign, in addition to Tivan's local team. To commemorate the commencement of drilling, Tivan disclosed it is hosting a ceremony with community leaders, local authorities and representatives of Autoridade Nacional dos Minerais Timor-Leste, I.P and Murak Rai Timor E.P. The filing states that the commencement of drilling represents a historic milestone for Timor-Leste's mineral resources sector.
