# Completion of Mutamba Mineral Sands Project Scoping Study Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/completion-of-mutamba-mineral-sands-project-scoping-study--af2513c1-dd84-4d80-850f-3cb9c2c9a68f Original source: https://www.rns-pdf.londonstockexchange.com/rns/4769G_1-2017-5-29.pdf Publisher: research Original announcement: Unknown date Analysis by Minestarters Atlas Atlas analysis published: 2026-10-20T00:08:54.022Z Atlas analysis updated: 2026-10-20T00:08:54.022Z - Company: Savannah Resources Plc - Ticker: SAV - Exchange: LSE - Region: Mozambique - Primary commodity: Mineral sands - Secondary commodities: Ilmenite, Rutile, Zircon, Titanium - Document categories: Other, Resource update, Agreement transaction - Extracted: 2026-10-20 00:08:54 UTC Narrative sentiment: 0.60 · Bullish ## Minestarters Atlas summary Savannah announced completion of the Mutamba scoping study, which outlines a 30-year mineral sands project in Mozambique with strong modelled economics. The release also includes resource-based mining inventory assumptions, production forecasts, capex, opex, and the consortium interest changes linked to delivering the study. Reasoning: This is primarily a scoping study announcement for the Mutamba Mineral Sands Project, with an associated resource-based mine plan and consortium update. The study outlines robust but preliminary project economics and development assumptions rather than finalized reserves or production. - Positive factor: completion of scoping study for Mutamba - Positive factor: modelled pre-tax NPV of US$154M to US$335M and IRR of 19% to 27% - Positive factor: 30-year mine life with estimated 451Mt mining inventory - Positive factor: projected production of 456,000tpa ilmenite and 118,000tpa non-magnetic concentrate - Negative factor: scoping study is low-level and insufficient to support Ore Reserves - Negative factor: financial outputs are modelled scenarios rather than completed operating results - Negative factor: resource figures are presented as mining inventory based on Indicated and Inferred Resources - Rubric flag: economic\_study classification — This release is primarily a scoping study / economic evaluation, but it also restates historical JORC resource rows used in the mine plan. Keep economic\_study as primary and treat resource\_update as secondary/background. - Rubric flag: resource extraction completeness — The document's resource table reports THM percentages by deposit and category; extraction above treats these as resource rows. The ilmenite/rutile/zircon percentages in the table are not added because they are grade fractions within the same table and the release presents them as product-mix style disclosures rather than separately labeled resource commodities. Facts used in scoring: 6 ## Classification and evidence **PFS-Supporting** Polarity: neutral Definition: Resource estimate prepared to support a Pre-Feasibility Study — requires adequate M&I component. Why it applies: The scoping study says the project will advance to PFS and then DFS, indicating this estimate supports further study work rather than a final investment decision. Evidence · text > we are now looking to commission a group to undertake this study once a tender process is complete. **JORC Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with JORC Code \(Australia\) — high reporting standard. Why it applies: The resource table is described as JORC 2012 reportable Mineral Resources. Evidence · text > JORC 2012 reportable Mineral Resources have been defined at Jangamo, Dongane and Ravene **QP/CP Signed** Polarity: positive Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience. Why it applies: The release names Colin Rothnie as the Competent Person responsible for the resource estimation. Evidence · text > The information in this document that relates to the resource estimation is based upon information compiled by Mr Colin Rothnie ## Extracted facts Stored fact records: 6.
