# BTR: Visible Gold Continues From TMH Extensional Drilling Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/btr-visible-gold-continues-from-tmh-extensional-drilling--c6189af9-a304-4316-8d40-7d97b2809aa8 Original source: https://www.asx.com.au/asx/v2/statistics/displayAnnouncement.do?display=pdf&idsId=03145909 Publisher: asx Original announcement: 2026-09-29T23:15:00.000Z Analysis by Minestarters Atlas Atlas analysis published: 2026-09-30T00:10:59.686Z Atlas analysis updated: 2026-09-30T00:10:59.686Z - Company: Brightstar Resources Limited - Ticker: BTR - Exchange: ASX - Region: Western Australia - Primary commodity: Gold - Secondary commodities: Lead, Iron ore, Copper, Zinc, Molybdenum - Document categories: Drill results - Extracted: 2026-09-30 00:11:00 UTC Narrative sentiment: 0.20 · Bullish ## Minestarters Atlas summary Brightstar Resources announced that extensional diamond drilling at its Two Mile Hill deposit, part of the Sandstone Gold Project, intersected a significantly wider mineralized tonalite unit with numerous visible gold occurrences. While assays are pending for the newly drilled holes TMHDD26005 and TMHDD26006, the observations suggest substantial potential for Mineral Resource upside at depth. The company also referenced previously reported strong gold intercepts from drillhole TMHRCD26020. Reasoning: Extensional drilling at Two Mile Hill confirmed a significantly wider mineralized tonalite unit with numerous visible gold occurrences, suggesting substantial potential for resource upside at depth, though actual assay results for these new holes are still pending. - Positive factor: Visible gold occurrences in new drilling - Positive factor: Extensional drilling confirms significant widening of mineralized tonalite unit - Positive factor: Deposit remains open at depth, indicating resource upside - Positive factor: Strong historical drill intercepts referenced - Negative factor: Assay results are pending for all new drill holes - Negative factor: Visible gold is not a substitute for quantitative assay data Facts used in scoring: 8 ## Classification and evidence **Visible Gold** Polarity: positive Story-specific tag Definition: No canonical definition is currently available. Why it applies: The document highlights 'Regular occurrences of visible gold intersected in deep diamond drilling' and lists 40 occurrences in Table 1. Evidence · text > Regular occurrences of visible gold intersected in deep diamond drilling at the Two Mile Hill deposit **Assays Pending** Polarity: negative Story-specific tag Definition: No canonical definition is currently available. Why it applies: The document explicitly states that assays are pending for all holes in the current program. Evidence · text > Assays are pending for all holes **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: The drilling is described as 'extensional drilling' and a 'significant extension of the previously interpreted Two Mile Hill deposit at depth'. Evidence · text > This is a significant extension of the previously interpreted Two Mile Hill deposit at depth **QA/QC Disclosed** Polarity: positive Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\). Why it applies: The document includes a detailed JORC Code, 2012 Edition – Table 1, outlining sampling techniques, quality control procedures, and competent person statements. Evidence · text > APPENDIX 1: JORC CODE, 2012 EDITION – TABLE 1 **Apparent Width Only** Polarity: negative Definition: Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness. Why it applies: The historical intercept from TMHRCD26020 is described as a 'broad, unconstrained intercept', indicating that true width is not known or stated. Evidence · text > broad, unconstrained intercept of 305.4m @ 1.82g/t Au from 351.9m ## Extracted facts Stored fact records: 8.
