The results reported today continue to demonstrate\nmineralization in areas currently classified as Inferred or, in some cases,\ntreated as waste in the existing block model, creating potential opportunities\nfor resource conversion, pit and mining sequence optimization, strip ratio\nimprovements and enhanced early-year mill feed.\n\nZ87 Intercept Highlights:\n* Hole 87-26-485 intersected 0.95 g/t gold equivalent (“AuEq”) (0.80 g/t\nAu, 1.11 g/t Ag, 0.10% Cu) over 129.05 m, including 3.38 g/t AuEq (2.97g/t Au,\n1.80 g/t Ag, 0.29 % Cu) over 22 m starting at 398 m downhole from an area of\ninferred material within the Z87 reserve pit (see Figures 1 and 2).\n\n* Hole 87-26-531 intersected 0.99 g/t gold equivalent (“AuEq”) (0.84 g/t\nAu, 1.20 g/t Ag, 0.10 % Cu) over 74.3 m, including 3.15 g/t AuEq (2.73 g/t Au,\n1.88 g/t Ag, 0.30 % Cu) over 3.3m starting at 468 m downhole from an area of\ninferred material within the Z87 reserve pit (see Figures 1 and 2).\n\n* Hole 87-26-529 intersected 1.15 g/t gold equivalent (“AuEq”) (1.00 g/t\nAu, 0.84 g/t Ag, 0.11 % Cu) over 45 m, including 5.42 g/t AuEq (4.73 g/t Au,\n5.45 g/t Ag, 0.46 % Cu) over 2 m starting at 579 m from an area of inferred\nmaterial 70 m below the Z87 reserve pit(see Figures 1 and 3).\n\n* Hole 87-26-515 intersected several intervals of mineralization in the\nhistorically unsampled Z87 hangingwall where the current resource model does\nnot contain mineralized blocks (see Figure 3 and Table 1).\nJustin Reid, CEO of Troilus, commented, “None of our 2026 drilling is\nincluded in the latest Resource and Reserve estimates, and we continue to see\nimpactful drill results from within and around the Z87 Reserve pit. We are\ntargeting Inferred material and historically unsampled intervals, and the\ndrilling is showing more extensive mineralization than is currently\nrepresented in the resource model. The results indicate mineralization in an\narea that is currently modeled as waste. Subject to further drilling,\ngeological modelling, engineering evaluation and incorporation into future\nmine-plan updates, the mineralization may have the potential to reduce waste\nmovement and improve strip ratios in this portion of the deposit.”.”\n\nZ87 Optimization Program\n\nZ87 was one of two zones previously mined by open pit during the former\nTroilus operation. Many of the historical drill holes used to define the\nformer mine reserve were not continuously sampled, leaving intervals of core -\nin some cases extending for several hundred metres - without assay data.\n\nFor the purposes of resource estimation, these unsampled intervals are\nassigned values equal to one-half of the laboratory detection limit, resulting\nin significant gaps within the current block model. The 2026 optimization\nprogram is systematically testing these areas to determine whether\nmineralization extends through historically unsampled intervals that are\npresently modelled as waste.\n\nThe program is also targeting Inferred material within and around the current\nZ87 Reserve pit, with the objective of collecting data to support potential\nconversion to the Indicated category and consideration for possible\nincorporation into future Mineral Reserve and mine-plan updates.\n\nThe results announced today build on earlier 2026 drilling at Z87 that has\ndemonstrated mineralization beyond and within the current Reserve pit,\nincluding broad intervals encountered in historically unsampled areas of the\nhangingwall (see press releases dated August 20, 2026\n(https://www.globenewswire.com/Tracker?data=2ef2kBen59Mcy3iVTYOEMjrxDeJdJHxvxLDACV7ykDuhUUNLLLfZEvFmL589OwhHItwm__PKi__hmvKFgnQrypuFtR9mRjBEBOKbH6zfVjeOCJBA7SV_kGh9e9TCGAKKcpM5RXL4utzWLHNB7QBkDANrl8vNR-rPqOjd7Frj5pFsOIGAuUCIGKB2FGu_z0CIOjNChtFYssjqBMmPEk7yDI3fUmiT958d8xdiCdmueiB0YuJ64szlmEVr3cuKwN53YFembKKzSbPo9zgLnTvlj00d0VnLoWX2pa1CTrWtAYc=),\nJuly 7, 2026\n(https://www.globenewswire.com/Tracker?data=hrWZEhVeGozS3mdl6akaOJlODE0P8TkpyS5pzjj9jYR6oUNyBP2XzWo7PLoMp1AorMqzcJzu67oS3azYXo4iIUFEKgGvOfCotwWmhGI1NDk2eWx1NjyWeS08mJQ2_WPloPxhoNCTl3gxAwM8DHTM2nUIrE-jCuNaWSc277PX4KwKSgiIQRU8eOjyUr6QqZ01E92QLGdlVZieWgft6-oBj6S6eu9KWoFE9Lg3vAjgo9-PM9xnnDwkOvQpRdeVmzV4SiLolI7LdWREnF1qtfAjpXJVmuuk0Ln3fBaR48HPVUU=)\nand June 25, 2026\n(https://www.globenewswire.com/Tracker?data=aqjQsnIypNbp6C0mbrBKhMdxx7glx3OBMW8BTlEAUmuwlNLmCwJIfRg1A5UhdyX1C6JzE1WKikddgHDvcdk3oO5kYJ-LLmz9Zv5pSb5c2fXROcrsocWwpxDPkURNm_fH9GpTq_oFZGZUdKGzA_w8vh8cW4QZQJ-ZOB6KqzxKOz46v8jeupbW89oe8f06GvxH_iZAks-75JekmVVg7mrLYso3oP54SQBU3ga7xz114QYzxXhxRAL6A6-HtgXUWg4FaWQqaedyEoT8Qf4YnUN0eQ==).)\n\nAll grades are uncut, and true thicknesses are approximately 75% to 90% of\ndrilled length.\n\n*The NI 43-101 technical report associated with the mineral Resources and\nReserves of the Troilus Project can be found on SEDAR+ at www.sedarplus.ca\nunder the Company’s issuer profile or on the Company’s website at\nwww.troilusmining.com\n\n\n\nFigure 1.

The main zone returned 129.05 metres\ngrading 0.95 g/t AuEq including 3.38 g/t AuEq over 22 metres, which includes\n4.34 g/t AuEq over 12.47 metres. This area of the reserve pit contains\ninferred blocks that are not incorporated into the current mine plan. This\ndrilling was planned with the goal of upgrading the resource to the Indicated\ncategory for consideration in future production schedules.\n\nOn the same section, 120 metres down dip, drillhole 87-26-531 returned 125.5\nmetres grading 0.74 g/t AuEq, including 74.3 metres grading 0.99 g/t AuEq from\nthe main zone of Z87, where it was targeting Inferred material. The\nhangingwall returned 20 metres grading 0.31 g/t AuEq and 41.4 metres grading\n0.28 g/t AuEq where the current block model does not contain mineralization,\nas this area is informed by historically unsampled drillholes.\n\nOn a section 50m south of 87-26-485 and 87-26 531 (Figure 1), drillhole\n87-26-529 returned 1.15 g/t AuEq over 45 metres within a broader zone of 0.51\ng/t AuEq over 154 metres from the main zone of Z87 approximately 70 metres\nbelow the reserve pit (see Figure 3). This hole also returned 73 metres\ngrading 0.35 g/t AuEq including 0.72 g/t AuEq over 13 metres from the Z87\nhangingwall and 0.53 g/t AuEq over 40 metres including 1.54 g/t AuEq over 8\nmetres from the footwall. These intercepts present significantly broader\nmineralization than is currently in the resource model.\n\n87-26-515 was drilled to target an area of historically unsampled material\napproximately 50 metres up dip of hole 87-26-529. This hole returned several\nintervals of mineralization where the current resource is unmineralized due to\nthe impacts of historically unsampled intervals being assigned half the lab\nanalysis detection limit for the purpose of resource estimation. These\nintercepts include 0.80 g/t AuEq over 8 metres including 1.48 g/t AuEq over 3\nmetres, 0.61 g/t AuEq over 12 metres including 1.52 g/t AuEq over 3.5 metres,\n1.15 g/t AuEq over 7 metres including 5.04 g/t AuEq over 1 metres and 93\nmetres grading 0.46 g/t AuEq, which including intercepts of 1.07 g/t AuEq over\n10 metres and 1.06 g/t AuEq over 10 metres.\n\nTo date, Troilus has released 39 drillholes totaling 14,521 metres of the\napproximately 24,000 metres allocated to the Z87 pit optimization program,\nwhich includes the targeting of Inferred and unsampled material within and\naround the reserve pit shell.\n\nTable 1.

taken from NQ core and\nsawed in half. One-half was sent for assaying at ALS Laboratory in Sudbury\nOntario, a certified independent commercial laboratory, and the other half was\nretained for results, cross checks, and future reference. A strict QA/QC\nprogram was applied to all samples; which included insertion of one certified\nmineralized standard and one blank sample in each batch of 25 samples. Every\nsample was processed with standard crushing to 85% passing 75 microns on 500 g\nsplits. Samples were assayed by one-AT (30 g) fire assay with an AA finish and\nif results were higher than 3.5 g/t Au, assays were redone with a gravimetric\nfinish. For QA/QC samples, a 50 g fire assay was done. In addition to gold,\nALS laboratory carried out multi-element analysis for ME-ICP61 analysis of 33\nelements four acid ICP-AES.\n\nQualified Person\n\nThe technical and scientific information in this press release has been\nreviewed and approved by Nicolas Guest, P.Geo., Exploration Manager, who is a\nQualified Person as defined by NI 43-101.

The results reported today continue to demonstrate\nmineralization in areas currently classified as Inferred or, in some cases,\ntreated as waste in the existing block model, creating potential opportunities\nfor resource conversion, pit and mining sequence optimization, strip ratio\nimprovements and enhanced early-year mill feed.\n\nZ87 Intercept Highlights:\n* Hole 87-26-485 intersected 0.95 g/t gold equivalent (“AuEq”) (0.80 g/t\nAu, 1.11 g/t Ag, 0.10% Cu) over 129.05 m, including 3.38 g/t AuEq (2.97g/t Au,\n1.80 g/t Ag, 0.29 % Cu) over 22 m starting at 398 m downhole from an area of\ninferred material within the Z87 reserve pit (see Figures 1 and 2).\n\n* Hole 87-26-531 intersected 0.99 g/t gold equivalent (“AuEq”) (0.84 g/t\nAu, 1.20 g/t Ag, 0.10 % Cu) over 74.3 m, including 3.15 g/t AuEq (2.73 g/t Au,\n1.88 g/t Ag, 0.30 % Cu) over 3.3m starting at 468 m downhole from an area of\ninferred material within the Z87 reserve pit (see Figures 1 and 2).\n\n* Hole 87-26-529 intersected 1.15 g/t gold equivalent (“AuEq”) (1.00 g/t\nAu, 0.84 g/t Ag, 0.11 % Cu) over 45 m, including 5.42 g/t AuEq (4.73 g/t Au,\n5.45 g/t Ag, 0.46 % Cu) over 2 m starting at 579 m from an area of inferred\nmaterial 70 m below the Z87 reserve pit(see Figures 1 and 3).\n\n* Hole 87-26-515 intersected several intervals of mineralization in the\nhistorically unsampled Z87 hangingwall where the current resource model does\nnot contain mineralized blocks (see Figure 3 and Table 1).\nJustin Reid, CEO of Troilus, commented, “None of our 2026 drilling is\nincluded in the latest Resource and Reserve estimates, and we continue to see\nimpactful drill results from within and around the Z87 Reserve pit. We are\ntargeting Inferred material and historically unsampled intervals, and the\ndrilling is showing more extensive mineralization than is currently\nrepresented in the resource model. The results indicate mineralization in an\narea that is currently modeled as waste. Subject to further drilling,\ngeological modelling, engineering evaluation and incorporation into future\nmine-plan updates, the mineralization may have the potential to reduce waste\nmovement and improve strip ratios in this portion of the deposit.”.”\n\nZ87 Optimization Program\n\nZ87 was one of two zones previously mined by open pit during the former\nTroilus operation. Many of the historical drill holes used to define the\nformer mine reserve were not continuously sampled, leaving intervals of core -\nin some cases extending for several hundred metres - without assay data.\n\nFor the purposes of resource estimation, these unsampled intervals are\nassigned values equal to one-half of the laboratory detection limit, resulting\nin significant gaps within the current block model. The 2026 optimization\nprogram is systematically testing these areas to determine whether\nmineralization extends through historically unsampled intervals that are\npresently modelled as waste.\n\nThe program is also targeting Inferred material within and around the current\nZ87 Reserve pit, with the objective of collecting data to support potential\nconversion to the Indicated category and consideration for possible\nincorporation into future Mineral Reserve and mine-plan updates.\n\nThe results announced today build on earlier 2026 drilling at Z87 that has\ndemonstrated mineralization beyond and within the current Reserve pit,\nincluding broad intervals encountered in historically unsampled areas of the\nhangingwall (see press releases dated August 20, 2026\n(https://www.globenewswire.com/Tracker?data=2ef2kBen59Mcy3iVTYOEMjrxDeJdJHxvxLDACV7ykDuhUUNLLLfZEvFmL589OwhHItwm__PKi__hmvKFgnQrypuFtR9mRjBEBOKbH6zfVjeOCJBA7SV_kGh9e9TCGAKKcpM5RXL4utzWLHNB7QBkDANrl8vNR-rPqOjd7Frj5pFsOIGAuUCIGKB2FGu_z0CIOjNChtFYssjqBMmPEk7yDI3fUmiT958d8xdiCdmueiB0YuJ64szlmEVr3cuKwN53YFembKKzSbPo9zgLnTvlj00d0VnLoWX2pa1CTrWtAYc=),\nJuly 7, 2026\n(https://www.globenewswire.com/Tracker?data=hrWZEhVeGozS3mdl6akaOJlODE0P8TkpyS5pzjj9jYR6oUNyBP2XzWo7PLoMp1AorMqzcJzu67oS3azYXo4iIUFEKgGvOfCotwWmhGI1NDk2eWx1NjyWeS08mJQ2_WPloPxhoNCTl3gxAwM8DHTM2nUIrE-jCuNaWSc277PX4KwKSgiIQRU8eOjyUr6QqZ01E92QLGdlVZieWgft6-oBj6S6eu9KWoFE9Lg3vAjgo9-PM9xnnDwkOvQpRdeVmzV4SiLolI7LdWREnF1qtfAjpXJVmuuk0Ln3fBaR48HPVUU=)\nand June 25, 2026\n(https://www.globenewswire.com/Tracker?data=aqjQsnIypNbp6C0mbrBKhMdxx7glx3OBMW8BTlEAUmuwlNLmCwJIfRg1A5UhdyX1C6JzE1WKikddgHDvcdk3oO5kYJ-LLmz9Zv5pSb5c2fXROcrsocWwpxDPkURNm_fH9GpTq_oFZGZUdKGzA_w8vh8cW4QZQJ-ZOB6KqzxKOz46v8jeupbW89oe8f06GvxH_iZAks-75JekmVVg7mrLYso3oP54SQBU3ga7xz114QYzxXhxRAL6A6-HtgXUWg4FaWQqaedyEoT8Qf4YnUN0eQ==).)\n\nAll grades are uncut, and true thicknesses are approximately 75% to 90% of\ndrilled length.\n\n*The NI 43-101 technical report associated with the mineral Resources and\nReserves of the Troilus Project can be found on SEDAR+ at www.sedarplus.ca\nunder the Company’s issuer profile or on the Company’s website at\nwww.troilusmining.com\n\n\n\nFigure 1.

The main zone returned 129.05 metres\ngrading 0.95 g/t AuEq including 3.38 g/t AuEq over 22 metres, which includes\n4.34 g/t AuEq over 12.47 metres. This area of the reserve pit contains\ninferred blocks that are not incorporated into the current mine plan. This\ndrilling was planned with the goal of upgrading the resource to the Indicated\ncategory for consideration in future production schedules.\n\nOn the same section, 120 metres down dip, drillhole 87-26-531 returned 125.5\nmetres grading 0.74 g/t AuEq, including 74.3 metres grading 0.99 g/t AuEq from\nthe main zone of Z87, where it was targeting Inferred material. The\nhangingwall returned 20 metres grading 0.31 g/t AuEq and 41.4 metres grading\n0.28 g/t AuEq where the current block model does not contain mineralization,\nas this area is informed by historically unsampled drillholes.\n\nOn a section 50m south of 87-26-485 and 87-26 531 (Figure 1), drillhole\n87-26-529 returned 1.15 g/t AuEq over 45 metres within a broader zone of 0.51\ng/t AuEq over 154 metres from the main zone of Z87 approximately 70 metres\nbelow the reserve pit (see Figure 3). This hole also returned 73 metres\ngrading 0.35 g/t AuEq including 0.72 g/t AuEq over 13 metres from the Z87\nhangingwall and 0.53 g/t AuEq over 40 metres including 1.54 g/t AuEq over 8\nmetres from the footwall. These intercepts present significantly broader\nmineralization than is currently in the resource model.\n\n87-26-515 was drilled to target an area of historically unsampled material\napproximately 50 metres up dip of hole 87-26-529. This hole returned several\nintervals of mineralization where the current resource is unmineralized due to\nthe impacts of historically unsampled intervals being assigned half the lab\nanalysis detection limit for the purpose of resource estimation. These\nintercepts include 0.80 g/t AuEq over 8 metres including 1.48 g/t AuEq over 3\nmetres, 0.61 g/t AuEq over 12 metres including 1.52 g/t AuEq over 3.5 metres,\n1.15 g/t AuEq over 7 metres including 5.04 g/t AuEq over 1 metres and 93\nmetres grading 0.46 g/t AuEq, which including intercepts of 1.07 g/t AuEq over\n10 metres and 1.06 g/t AuEq over 10 metres.\n\nTo date, Troilus has released 39 drillholes totaling 14,521 metres of the\napproximately 24,000 metres allocated to the Z87 pit optimization program,\nwhich includes the targeting of Inferred and unsampled material within and\naround the reserve pit shell.\n\nTable 1.

taken from NQ core and\nsawed in half. One-half was sent for assaying at ALS Laboratory in Sudbury\nOntario, a certified independent commercial laboratory, and the other half was\nretained for results, cross checks, and future reference. A strict QA/QC\nprogram was applied to all samples; which included insertion of one certified\nmineralized standard and one blank sample in each batch of 25 samples. Every\nsample was processed with standard crushing to 85% passing 75 microns on 500 g\nsplits. Samples were assayed by one-AT (30 g) fire assay with an AA finish and\nif results were higher than 3.5 g/t Au, assays were redone with a gravimetric\nfinish. For QA/QC samples, a 50 g fire assay was done. In addition to gold,\nALS laboratory carried out multi-element analysis for ME-ICP61 analysis of 33\nelements four acid ICP-AES.\n\nQualified Person\n\nThe technical and scientific information in this press release has been\nreviewed and approved by Nicolas Guest, P.Geo., Exploration Manager, who is a\nQualified Person as defined by NI 43-101. Mr. Guest is an employee of Troilus\nand is not independent of the Company under NI 43-101.\n\nAuEq Disclosure\n\nThe formulas used to calculate equivalent values for resources are as follows,\nfor 87 Pit AuEq = Au + 1.3365*Cu +0.0136 Ag, for J Pit AuEq = Au + 1.3618Cu\n+0.0137 Ag, for SW Pit AuEq = Au + 1.3856Cu +0.01141 Ag, for X22 Pit AuEq = Au\n+ 1.3168Cu +0.0136 *Ag. AuEq was calculated using metal prices of $2,415/oz\nAu; $4.60/lb Cu and $32.00/oz Ag and recoveries of 84.5% for Au, 86.9% for Ag\nand 88.1% for Cu in the J pit, 85.9% for Au, 87.6% for Ag and 87.9% for Cu in\nthe 87 pit, 82.1% for Au, 87.1% for Ag and 87.1% for Cu in the SW pit and 85.6\n% for Au, 87.0% for Ag and 86.3% for Cu in the X22 pit.\n\nAbout Troilus Mining Corp.\n\nTroilus Mining Corp. is a Canadian development-stage mining company focused on\nthe systematic advancement of the former gold and copper Troilus Mine towards\nproduction.

Generally, forward-looking statements can be\nidentified by the use of forward-looking terminology such as “plans”,\n“expects” or “does not expect”, “is expected”, “budget”,\n“scheduled”, “estimates”, “forecasts”, “intends”,\n“continue”, “anticipates” or “does not anticipate”, or\n“believes”, or variations of such words and phrases or statements that\ncertain actions, events or results “may”, “could”, “would”,\n“will”, “might” or “will be taken”, “occur” or “be\nachieved”. \n\nForward-looking statements are made based upon certain assumptions and other\nimportant facts that, if untrue, could cause the actual results, performances\nor achievements of Troilus to be materially different from future results,\nperformances or achievements expressed or implied by such statements. Such\nstatements and information are based on numerous assumptions regarding present\nand future business strategies and the environment in which Troilus will\noperate in the future. Certain important factors that could cause actual\nresults, performances or achievements to differ materially from those in the\nforward-looking statements include, amongst others, currency fluctuations, the\nglobal economic climate, dilution, share price volatility and competition.\nForward-looking statements are subject to known and unknown risks,\nuncertainties and other important factors that may cause the actual results,\nlevel of activity, performance or achievements of Troilus to be materially\ndifferent from those expressed or implied by such forward-looking statements,\nincluding but not limited to: there being no assurance that the exploration\nprogram or programs of the Company will result in expanded mineral resources;\nrisks and uncertainties inherent to mineral resource and reserve estimates;\nthe high degree of uncertainties inherent to feasibility studies and other\nmining and economic studies which are based to a significant extent on various\nassumptions; variations in gold prices and other metals, exchange rate\nfluctuations; variations in cost of supplies and labour; receipt of necessary\napprovals; availability of financing for project development; uncertainties\nand risks with respect to developing mining projects; general business,\neconomic, competitive, political and social uncertainties; future gold and\nother metal prices; accidents, labour disputes and shortages; environmental\nand other risks of the mining industry, including without limitation, risks\nand uncertainties discussed in the Company’s latest Annual Information Form,\nits technical reports and other continuous disclosure documents of the Company\navailable under the Company’s profile at www.sedarplus.ca. Although Troilus\nhas attempted to identify important factors that could cause actual results to\ndiffer materially from those contained in forward-looking statements, there\nmay be other factors that cause results not to be as anticipated, estimated or\nintended. There can be no assurance that such statements will prove to be\naccurate, as actual results and future events could differ materially from\nthose anticipated in such statements. Accordingly, readers should not place\nundue reliance on forward-looking statements. Troilus does not undertake to\nupdate any forward-looking statements, except in accordance with applicable\nsecurities laws.\n\nPhotos accompanying this announcement are available at\n\nhttps://www.globenewswire.com/NewsRoom/AttachmentNg/dee0a1c1-3e96-4fd7-bef4-396237e24508\n\nhttps://www.globenewswire.com/NewsRoom/AttachmentNg/803a7ee1-e899-44f4-9cd8-8fac115290a9\n\nhttps://www.globenewswire.com/NewsRoom/AttachmentNg/8d866bb1-4c22-4f4c-9625-c2d7dc7f4893\n\n(https://www.globenewswire.com/NewsRoom/AttachmentNg/c11b01e1-dbed-4e5d-a5f6-bec3bc13a048)\nFigure 1 \n(https://www.globenewswire.com/NewsRoom/AttachmentNg/dee0a1c1-3e96-4fd7-bef4-396237e24508/en)\nPlan map with the reported drill hole locations from Z87Figure 2 \n(https://www.globenewswire.com/NewsRoom/AttachmentNg/803a7ee1-e899-44f4-9cd8-8fac115290a9/en)\nCross section showing results for drillhole 87-26-485 and 87-26-531.Figure 3 \n(https://www.globenewswire.com/NewsRoom/AttachmentNg/8d866bb1-4c22-4f4c-9625-c2d7dc7f4893/en)\nCross section showing results for drillhole 87-26-515 and 87-26-529.\n\n\nGlobeNewswire, Inc. 2026"},"type":"article","timestamp":"2026-09-17T11:00:01.699181866Z","server_sent_at_ms":1789642801699},"received_at":"2026-09-17T11:00:01.770Z","source_url":null},"analysis":{"id":"134974","press_release_id":"146140","analysis_json":{"industry":{"label":"Gold","sector":"Materials"},"redFlags":["intercepts are from Inferred material and historically unsampled intervals — not in the current resource model, and conversion is not assured","claimed mine-plan benefits (strip ratio, early-year mill feed) are contingent on further drilling, geological modelling and engineering","much of the mineralization is low-grade, with broad intervals at roughly 0.2-0.5 g/t AuEq","development-stage issuer with no production revenue; project economics depend on financing and approvals"],"eventType":"operations_update","narrative":"Troilus Mining reported the fourth batch of results from its Z87 optimization drill program in north-central Quebec, covering nine holes totaling 4,728 metres.
