Announcement PDF ASX ANNOUNCEMENT 30 OCTOBER 2026 Critical Resources Limited – www.criticalresources.com.au Level 45, 108 St George's Tce, Perth WA 6000 P: +61 (8) 9465 1024 E. info@criticalresources.com.au ASX:CRR Quarterly Activities Report – September 2026 September 2026 Quarter Highlights SURINAME – GOLD - First-mover ASX-listed gold exploration in Suriname: During the Quarter, the Company secured exclusivity to acquire a 90% interest in two granted gold exploitation (mining) rights in Suriname's Guiana Shield – the Gonini Gold Project (~164 km²) and the Greenstars Gold Project (~35 km²) – a combined ~199 km² of granted gold tenure. - Portfolio growth after the Quarter: exclusivity secured over a third gold project, Gadu Manda (~29 km², ~4 km from Zijin's Rosebel open pits), taking the Suriname portfolio under exclusivity to ~228 km². Management is in-country completing due diligence and reviewing further opportunities. The Company has also engaged Guiana Shield structural geophysics specialists to fast-track structural targeting across several areas. NEW ZEALAND – GOLD & CRITICAL MINERALS - Lammerlaw – Stony Creek anomalies: Completed follow-up soil sampling along a ~5.4 km transect defining multiple arsenic–antimony–tungsten anomalies over a ~3.2 km section, with a peak value of 238 ppm As (pXRF). - Silver Peaks – three priority targets: a review of more than 1,250 historical soil and stream-sediment records defined three gold–antimony targets for field verification. CANADA – MAVIS LAKE LITHIUM PROJECT – ONTARIO - Red Hat claims staked: two additional claim cells staked over the Red Hat gold target expanding the Mavis Lake land holding. The additional claims are interpreted to contain historical drill hole RH11-03 (reported 1.2 m @ 9.174 g/t Au). NEW SOUTH WALES - HALLS PEAK PROJECT - Mayview land access progressing: negotiation of the land access agreement for a low-impact soil geochemistry and mapping program is ongoing. SOLID-STATE LITHIUM-ION BATTERY TECHNOLOGY - Peer-reviewed validation of the DSD dry cathode process was published in the peer-reviewed publication Electrochimica Acta – reporting ~154 mAh/g, ~85% capacity retained over 500 cycles at 1C and coulombic efficiency above 99.5% (coin cell, liquid-electrolyte reference). - Full-format pouch cell developed: a DSD LFP/LLZO pouch cell sustained more than 780 hours (65 cycles) of continuous cycling at 0.2C, with ~145 mAh/g initial capacity and ~75% retention. Optimisation work is ongoing. - CSIRO collaboration under a Kick-Start co-funded research project with Australia’s national science agency commenced at Lab22, applying digital-twin modelling to optimise the DSD process and develop a scale-up pathway. TWO-PHASE DATA CENTRE COOLING TECHNOLOGY - Technical Adviser appointed: Data centre liquid cooling specialist engaged to support the development program, with ongoing work to finalise proof-of-concept (POC) designs and testing program. CORPORATE - $1.6 million placement: Tranche 1 settled on 15 September 2026, raising $1,125,000 in cash (before costs); Tranche 2 ($475,000 of director participation) is subject to shareholder approval. Cash and cash equivalents of A$1.58 million (unaudited) at 30 September 2026. Critical Resources Limited – www.criticalresources.com.au Level 45, 108 St George's Tce, Perth WA 6000 P: +61 (8) 9465 1024 E. info@criticalresources.com.au ASX:CRR Critical Resources Limited (‘Critical Resources’ or the ‘Company’, ASX:CRR) is pleased to report on its activities for the quarter ending 30 September 2026 (‘the Quarter’). During the Quarter, the Company secured exclusivity over its first gold projects in Suriname, advanced its exploration portfolio in New Zealand, Canada and New South Wales, progressed its solid-state battery program to extended full-format pouch- cell testing, and continued to finalise proof-of-concept (POC) designs for its first two-phase cooling technology. SURINAME – GOLD – GUIANA SHIELD The September Quarter marked a defining step for Critical Resources, with the Company’s entry into the Suriname gold sector. The Company secured exclusivity over two granted gold exploitation (mining) rights – Gonini (~164 km²) and Greenstars (~35 km²) – and, after the Quarter, a third project at Gadu Manda (~29 km²), building a ~228 km² portfolio under exclusivity in a proven gold province that remains under-explored by modern standards (refer to ASX:CRR announcements 23 September 2026, 28 September 2026 and 20 October 2026). Management is currently in-country completing legal, title and technical due diligence with the vendors, in- country counsel and advisers, meeting with key officials and local communities, and reviewing further project opportunities across Suriname. WHY SURINAME Suriname offers a rare combination for a junior explorer: a proven gold jurisdiction with established mining law, large producing mines, and a greenstone belt that has seen only a fraction of the modern exploration of its geological equivalent in West Africa. - A proven gold producer. Zijin Mining’s (SSE:601899) Rosebel mine (in production since 2004) has reportedly produced 5.65 Moz of gold to 2021 and was acquired by Zijin from IAMGOLD for US$360 million in 2023. Newmont's Merian mine (in production since 2016) commenced with 5.1 Moz of gold reserves. Gold accounted for ~79% of Suriname's exports (~US$2.0 billion) in 20249. - The Birimian of South America – under-explored. The Guiana Shield and West Africa's Birimian greenstone terranes are interpreted to have been a single geological province before the opening of the Atlantic. The Birimian hosts an estimated 500+ Moz of discovered gold; the Guiana Shield around 100 Moz, after materially less systematic modern exploration. - Major capital is moving into Suriname. Gold Fields Limited (JSE: GFI) completed a C$77 million investment in Founders Metals (TSXV:FDR) in September 2026, taking its holding to ~19.9%, and La Mancha holds 19.9% of both Miata Metals (TSXV:MMET) and Greenheart Gold (TSXV:GHRT)– all Canadian-listed explorers working the same Suriname greenstone belt.1,2,3,13 - Limited ASX exposure. Australian investors have had very little direct listed exposure to Suriname gold. To the Company's knowledge, Critical Resources is the first ASX-listed Australian company in many decades to hold exclusivity over rights to explore granted gold tenure in Suriname. - Recent discoveries by other companies have been on ground first worked by small-scale miners. Founders Metals has reported 28.0 m @ 14.27 g/t Au at Upper Antino, and Miata Metals has reported 30 m @ 4.06 g/t Au and 63 m @ 1.44 g/t Au at Sela Creek – both on ground first worked by small-scale miners. These results are from other companies' projects, reported under NI 43-101 and not in accordance with JORC, and are not indicative of mineralisation at the Company's projects.1,2 Critical Resources Limited – www.criticalresources.com.au Level 45, 108 St George's Tce, Perth WA 6000 P: +61 (8) 9465 1024 E. info@criticalresources.com.au ASX:CRR - Established mining title framework. Mineral rights are granted by the Geology and Mining Department (GMD) under the Mining Decree 1986 in a three-tier hierarchy of reconnaissance, exploration and exploitation rights. Exploitation rights carry the exclusive right to explore, mine, process and sell, for terms of up to 25 years. The vendors hold Gonini and Greenstars as granted exploitation rights, not applications; the Company's interest remains subject to due diligence and conditions precedent.6,9 Figure 1 – Location of the Gadu Manda, Greenstars and Gonini Gold Projects and other gold deposits within the Suriname greenstone belt. Resource and reserve figures shown for third-party deposits are drawn from their owners’ public disclosures, have not been verified by the Company and are not necessarily reported in accordance with the JORC Code. GONINI GOLD PROJECT (EXCLUSIVITY – 90% PROPOSED) Gonini is the Company's foundation asset in Suriname: two granted exploitation rights covering ~164 km² in the historic Sara Creek district, where gold was discovered in 1876 and Suriname's first gold rush began. The Project lies within the Marowijne greenstone belt, approximately 66 km from Newmont's Merian mine and 88 km from Zijin's Rosebel mine, and is interpreted to straddle the Paramaka greenstone–granitoid contact, a setting associated with orogenic gold mineralisation elsewhere in the region. Generations of small-scale miners have worked alluvial, saprolite and weathered-bedrock gold at Sara Creek, yet there is no record of modern systematic exploration on the Gonini rights to test their hard-rock potential. Existing workings expose saprolite and weathered bedrock, giving the Company immediate starting points for mapping, sampling and target generation. The Vendor, N.V. Gonini Mining Company, an Critical Resources Limited – www.criticalresources.com.au Level 45, 108 St George's Tce, Perth WA 6000 P: +61 (8) 9465 1024 E. info@criticalresources.com.au ASX:CRR arm's length private Surinamese company, has held rights in the district since 2012 (refer announcement 23 September 2026). GREENSTARS GOLD PROJECT (EXCLUSIVITY – 90% PROPOSED) Greenstars adds a second, complementary position in the greenstone belt that hosts Zijin's Rosebel mine and its Saramacca satellite operation. The Project is a single granted right of exploitation for gold covering ~35 km² in the Para District, west of the Saramacca River and approximately 35 km west of Rosebel. Small- scale artisanal miners are actively working alluvial gold on the Project. The Vendor, Greenstars Resources N.V., reports sampling, trenching and shallow drilling between 2018 and 2020 and has identified two areas it considers prospective; this work has not been verified by the Company and no Exploration Results are reported (refer announcement 28 September 2026). SUBSEQUENT EVENTS – BUILDING MOMENTUM - Guiana Shield structural specialists engaged (5 October 2026): GexplOre, whose team has worked on around 20 gold projects across the Guiana Shield, including structural work at G Mining Ventures' Oko West (Guyana) and Founders Metals' Antino (Suriname), was engaged to complete a two-stage structural interpretation – a detailed study of two priority areas at Gonini and a regional review of more than 6,000 km² of the surrounding greenstone belt. Stage 1 results are expected by mid-November 2026. - Third project – Gadu Manda (20 October 2026): exclusivity secured to acquire a 90% interest in the Gadu Manda Gold Project, a granted exploration permit covering ~29 km² in the Brokopondo District, with its eastern boundary ~4 km from Rosebel's western open pits. Small-scale miners have worked the northern part of the permit, exposing quartz veining. Figure 2 – Aerial view of small-scale workings in primary material on the Gadu Manda Project - October 2026. Critical Resources Limited – www.criticalresources.com.au Level 45, 108 St George's Tce, Perth WA 6000 P: +61 (8) 9465 1024 E. info@criticalresources.com.au ASX:CRR - Management in-country (12 October 2026): management visited the Gonini, Greenstars and Gadu Manda projects, progressing due diligence and preparation of binding agreements with both Suriname vendors, and began assembling a field crew for first-pass geochemistry sampling at Gadu Manda. STRATEGY AND NEXT STEPS The Company's objective is to build a strategic portfolio of gold projects in Suriname, organised around district-scale positions in proven greenstone corridors. Near-term priorities include: - Complete due diligence and binding agreements on Gonini, Greenstars and Gadu Manda, and satisfy the conditions precedent. - Structural targeting: integrate GexplOre's structural interpretations to focus field programs across the Suriname projects on the shear zones, fold hinges and granitoid–greenstone contacts that control orogenic gold in the region. - First field programs: site verification and sampling of existing artisanal workings, stream-sediment and ridge sampling, then first-pass auger geochemistry into saprolite to generate and rank hard-rock gold targets. - Grow the land position: continue to assess further opportunities across Suriname to expand the portfolio, subject to completion of the current acquisitions. Cautionary statement – The Gonini, Greenstars and Gadu Manda projects are greenfield exploration projects. No Exploration Results, Exploration Targets, Mineral Resources or Ore Reserves are reported. References to nearby mines, to peer companies and to exploration results reported by other parties are drawn from public disclosures, have not been verified by the Company, are provided for regional context only and are not indicative of mineralisation on the Company's projects. Completion of each acquisition is subject to conditions precedent, including due diligence, regulatory approvals and binding agreements, and there is no certainty that any acquisition will complete. NEW ZEALAND – GOLD & CRITICAL MINERALS Critical Resources holds a 1,694 km² exploration portfolio across the Otago and Reefton regions of New Zealand's South Island, covering six permits in prospective orogenic gold, antimony and tungsten belts. During the Quarter, the Company completed follow-up soil geochemistry at Lammerlaw, defined three priority targets at Silver Peaks from historical data, and continued planning a follow-up drilling program at Cap Burn. CAP BURN GOLD PROJECT Planning continued during the Quarter for a follow-up drilling program at the Cap Burn Gold Project (EP 60300, 100%), building on the inaugural RC program reported on 25 March 2026, which intersected 7 m @ 0.37 g/t Au from 65 m, including 1 m @ 1.29 g/t Au (CBRC017), and 16 m @ 0.22 g/t Au from 46 m (CBRC021). The program is being designed to test the untested down-plunge extension beneath the Cap Burn Fault, together with expanded soil geochemistry and structural mapping along the ~10 km corridor. Drilling remains in planning and is being scheduled in conjunction with the landowner. Critical Resources Limited – www.criticalresources.com.au Level 45, 108 St George's Tce, Perth WA 6000 P: +61 (8) 9465 1024 E. info@criticalresources.com.au ASX:CRR LAMMERLAW GOLD PROJECT Follow-up soil geochemistry was completed at the Stony Creek target on the western side of the Lammerlaw Gold Project (refer to ASX:CRR announcement 11 August 2026). A total of 143 soil samples were collected along a ~5.4 km north–south transect, identifying multiple arsenic–antimony–tungsten (As–Sb–W) anomalies concentrated within a ~3.2 km section of the target. - Strong arsenic response: sample A1583 returned 238 ppm As and 25 ppm Sb (pXRF), approximately 14 times the program median of 17 ppm As. - Supporting pathfinders: results include up to 31 ppm Sb and 36 ppm W, in an area with historic antimony workings and known tungsten anomalism. - Targeting narrowed: coincident As–Sb–W responses occur at several separate locations, including ten samples at or above 30 ppm As. Previously reported rock-chip sampling at Devils Creek, ~13 km east of Stony Creek within the same permit, returned up to 5.42 g/t Au (refer to ASX:CRR announcement 26 May 2026). No drilling has been completed on the permit. Infill soil sampling, structural mapping, rock-chip sampling and laboratory assays are planned to define which anomalies warrant drill testing. Cautionary statement – Portable XRF (pXRF) readings cited in this report are qualitative spot measurements and should not be considered equivalent to laboratory assay results. pXRF values are subject to variability due to sample heterogeneity, surface effects and instrument limitations. They are intended only as an indication of elemental presence and relative abundance and are not representative of bulk grade or mineralisation. As gold is not analysed by pXRF, no grades for gold have been calculated. SILVER PEAKS GOLD–ANTIMONY PROJECT A desktop review of more than 1,250 historical soil and stream-sediment records, together with two historical antimony occurrences, defined three priority targets within the 497.69 km² Silver Peaks Prospecting Permit (PP 61275), in which the Company holds a 90% interest through its wholly owned subsidiary Goldfire Resources Limited (refer to ASX:CRR announcement 3 September 2026): - Lamb Hill–Three O'Clock: a six-sample gold–arsenic stream anomaly and two historical antimony occurrences within the interpreted continuation of a northwest-trending mineralised structural system. - Stone Burn South: historical BLEG stream-sediment results of 45.2 and 39.3 ppb Au, supported by later pXRF soil results of up to 68 ppm As and 17 ppm Sb. - Northern Soil Anomaly: multiple historical gold–arsenic soil-composite results, including 16.0 ppb Au with 34 ppm As. Stone Burn South and the Northern Soil Anomaly sit immediately south of OceanaGold's Macraes gold camp. A focused field program is intended to assess the three targets; any advance to geophysics or drilling would depend on the results of that work and on the relevant permits and approvals. Cautionary statement – The historical results reported in this announcement were generated by previous explorers and have been reviewed by the Company in accordance with the JORC Code 2012 on the basis described in Appendix 1 of the Company’s 3 September 2026 announcement and considered reliable for the stated context. Critical Resources has not resampled the historical sites or repeated the original analyses Critical Resources Limited – www.criticalresources.com.au Level 45, 108 St George's Tce, Perth WA 6000 P: +61 (8) 9465 1024 E. info@criticalresources.com.au ASX:CRR and nothing has come to the attention of the Company that causes it to question the accuracy or reliability of the exploration results. The results are used to define areas for field follow-up and do not establish bedrock grade, width or mineralised continuity. These results have not been reported in accordance with the JORC Code 2012. A Competent Person has not done sufficient work to disclose the exploration results in accordance with the JORC Code 2012 and it is possible that following further evaluation and/or exploration work that the confidence in the prior reported exploration results may be reduced when reported under the JORC Code 2012. Refer to ASX:CRR announcement 3 September 2026 CROESUS GOLD-TUNGSTEN PROJECT Following the high-grade tungsten channel sampling at Granite Creek (up to 16.63% WO₃, refer to ASX:CRR announcement 23 June 2026) and the lodgement of an Extension of Land application (refer to ASX:CRR announcement 14 May 2026), no material activities were undertaken during the Quarter. MAVIS LAKE – LITHIUM – ONTARIO, CANADA NORTHERN CORRIDOR GEOCHEMISTRY Whole-rock lithogeochemical results from the 2026 field program across the Corona Pegmatite Field and adjacent Northern Prospects were received during the Quarter (refer to ASX:CRR announcement 17 July 2026). The 10-day program collected 106 rock samples from 14 pegmatite bodies (six newly identified), with 74 structural measurements and mapping of 161 outcrops, approximately 4 km north of the existing 8.0 Mt @ 1.07% Li₂O Mineral Resource. Granitic-hosted pegmatites within the Northern Prospects returned K/Rb ratios as low as 17.4, with enrichment in rubidium (up to 5,510 ppm), caesium (up to 221 ppm), tantalum (up to 53 ppm) and beryllium, consistent with highly evolved lithium-caesium-tantalum (LCT) pegmatite systems. The strongest fractionation signatures occur within the northern claim package acquired in August 2025, while pegmatites in the Corona field show only slight to moderate fractionation. The results will be integrated with the geological, structural and geophysical datasets to prioritise follow-up across the Gullwing, Tot, Little Wing, Coates, Drope and Corona target areas. RED HAT CLAIMS STAKED The Company's wholly owned subsidiary, Canada Critical Resources Corp, staked two additional claim cells (1054602 and 1054603, ~40 ha) over the Red Hat gold target within the Mavis Lake Project (refer to ASX:CRR announcement 19 August 2026). The claims are interpreted to contain historical diamond drill hole RH11-03, reported in historical records to have intersected 9.174 g/t Au over 1.2 m from 133.8 m. Red Hat forms part of an underexplored ~14 km east–west polymetallic trend hosted by felsic to intermediate volcanic rocks. No purchase consideration or royalty is payable for the staking. Cautionary Statement: The RH11-03 drill hole and Red Hat channel sample exploration results have not been reported in accordance with the JORC Code 2012. A Competent Person has not done sufficient work to disclose the exploration results in accordance with the JORC Code 2012 and it is possible that following further evaluation and/or exploration work that the confidence in the prior reported exploration results may be reduced when reported under the JORC Code 2012. Nothing has come to the attention of the Company that causes it to question the accuracy or reliability of the exploration results; however, the Company has not independently validated the exploration results and therefore is not to be regarded as reporting, adopting or endorsing those results (refer announcement 19 August 2026).

PERMITTING, ADVISORY AND GOVERNMENT ENGAGEMENT SLR Consulting delivered the project-wide Permitting Road Map for the Mavis Lake Lithium Project during the Quarter, aligning federal and provincial approval requirements with the Project's development milestones. The Company's expenditure obligations at Mavis Lake are met through to 2028, allowing the Project to be advanced on a capital-light basis while lithium markets recover. Since acquiring the Project in 2022, the Company has completed more than 58,000 metres of drilling, delivering a maiden 8 Mt @ 1.07% Li₂O JORC Inferred Mineral Resource (May 2023) and an 18–29 Mt @ 0.8– 1.2% Li₂O JORC Exploration Target (May 2024). Cautionary statement – The potential quantity and grade of the Exploration Target is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource, and it is uncertain if further exploration will result in the estimation of a Mineral Resource. Please refer to the Exploration Target Cautionary Statement (Appendix A) and ASX:CRR announcement dated 22 May 2024 for further information.

Field mapping previously completed by the Company identified high-grade antimony-gold mineralisation in historic dumps of shallow underground workings, with rock assays including 52.3% Sb (MVS17), 38.3% Sb (MVS8) and 15.35% Sb and 2.71 g/t Au (MVS11) (refer to ASX:CRR announcement 16 December 2024). During the Quarter, agreements for land access to support a low-impact soil geochemistry and geological mapping program were substantially prepared for execution. Separately, the Company has issued a formal access notice under section 142 of the Mining Act 1992 (NSW) to the landowners of the adjoining Eastview property within EL 9428. Field work will commence once access is in place. Figure 4 – Mayview Antimony Prospect with surface rock samples. SOLID-STATE LITHIUM-ION BATTERY EVALUATION PROGRAM During the Quarter, the Company's solid-state lithium-ion battery program at the South Dakota School of Mines & Technology (SDM), within the US National Science Foundation (NSF)-supported Centre for Solid-State Electric Power Storage (CEPS), received independent peer-reviewed validation of the Dry Supersonic Deposition (DSD) process, completed extended full-format pouch-cell testing, and added CSIRO as a research collaborator. The Company's strategy is to commercialise the technology through licensing rather than by manufacturing cells itself. Critical Resources Limited – www.criticalresources.com.au Level 45, 108 St George's Tce, Perth WA 6000 P: +61 (8) 9465 1024 E. info@criticalresources.com.au ASX:CRR PEER-REVIEWED VALIDATION OF THE DSD PROCESS On 2 July 2026, the Company reported that peer-reviewed research validating the DSD cathode process had been published in Electrochimica Acta (Rodmyre et al., Vol. 574, 2026, article 149386). The first unoptimised DSD trials, in coin-cell format on a liquid-electrolyte reference, delivered: - Near-theoretical capacity: approximately 154 mAh/g, close to the theoretical capacity of LFP. - Durability: approximately 85% capacity retained over 500 cycles at 1C (~1,250 hours), with coulombic efficiency above 99.5%. - Dry manufacturing: the cathode is built in a single dry step directly onto the current collector, with no toxic solvents, polymer binders or drying ovens. FULL-FORMAT POUCH CELL SUSTAINS A MONTH OF CYCLING On 10 September 2026, the Company reported completion of extended retention testing of a single hand- assembled, full-format laboratory pouch cell built with the DSD LFP/LLZO cathode matrix and a liquid reference electrolyte: - Extended cycling: more than 780 hours of continuous cycling at 0.2C, an industry-standard rate for retention testing. - Cathode chemistry active throughout: initial specific capacity of ~145 mAh/g and ~75% retention after 65 cycles, with the characteristic LFP voltage plateau present in every cycle and coulombic efficiency near 100% for most of the test. - Optimisation focus defined: the results indicate that full-format cycle life is a cell-engineering matter rather than a material limitation, defining where optimisation effort now focuses. CSIRO COLLABORATION During the Quarter, the Company initiated a collaborative research project with CSIRO, co-funded through CSIRO's Kick-Start program. The project is being undertaken at Lab22, CSIRO's advanced additive and robotic manufacturing facility in Clayton, Victoria, applying digital modelling to optimise the DSD process and develop a scale-up pathway. The Company intends to use the outcomes to scope a subsequent, larger program of work with CSIRO. For clarity, all cell results to date use a liquid reference electrolyte, and the Company's proprietary Amorphous Solid-State Electrolyte (ASE) has not yet been integrated into a complete cell. Integrating the ASE with the DSD process is the next stage toward an all-solid-state cell. This is laboratory-scale work, not commercial manufacturing. TWO-PHASE DATA CENTRE COOLING TECHNOLOGY The Company holds an exclusive worldwide licence from NTUitive Pte Ltd, the innovation and enterprise company of Nanyang Technological University, Singapore (NTU), over a two-phase spray cooling technology portfolio for data centre electronics and lithium-ion batteries (refer to ASX:CRR announcement 21 May 2026). The technology sprays a non-conductive (dielectric) fluid directly onto heat-generating chips, where it boils to remove heat before being condensed and recirculated in a sealed loop. It is designed to operate with near-ambient (~30°C) coolant, without refrigeration chillers or evaporative cooling towers.

Mr Martinez Gurrea is a High-Powered Computing (HPC) and data-centre liquid cooling specialist with more than 14 years of mechanical and thermal engineering experience, including direct-to-chip and immersion cooling across hyperscale data centre environments and product ownership of immersion cooling at Submer Technologies. During the Quarter, work continued with Capgemini Engineering and NTU on the proof-of-concept (POC) design and budget. The cooling program is a laboratory-based, stage-gated research and evaluation activity. The Company has no revenue from, and no binding commercial agreement for, the technology. Mineral exploration remains the Company's main undertaking.
