Omai Gold Drills 1.0 g/t Au over 774m at Gilt Creek, Including 2.0 g/t Au over 64m and 1.9 g/t Au over 48m
Omai Gold Mines (OMGGF) has announced significant drilling results from its first hole at the Gilt Creek gold deposit in Guyana. The hole intersected 774m of gold mineralization averaging 1.0 g/t Au, including higher-grade sections of 2.0 g/t Au over 64.0m and 1.9 g/t Au over 48.0m.
The drilling extended known gold mineralization approximately 200m laterally beyond previous limits, with 38 separate occurrences of visible gold identified. The hole reached a vertical depth of 850m and ended while still within the mineralized intrusion. This is the first drill hole at Gilt Creek since 2007, when the deposit was outlined with 46 holes totaling 27,000 metres.
The company plans to incorporate Gilt Creek into an updated Preliminary Economic Assessment (PEA) in Q3 2025, which is expected to significantly enhance the production profile and economics of the combined Omai Gold Project. The Gilt Creek deposit currently holds Indicated Resources of 1,151,000 ounces gold averaging 3.22 g/t Au and Inferred Resources of 665,000 ounces gold averaging 3.35 g/t Au.
Omai Gold Mines (OMGGF) ha annunciato risultati di perforazione significativi dal suo primo foro presso il giacimento aurifero di Gilt Creek in Guyana. Il foro ha intercettato 774m di mineralizzazione aurifera con una media di 1,0 g/t Au, inclusi segmenti di qualità superiore di 2,0 g/t Au su 64,0m e 1,9 g/t Au su 48,0m.
La perforazione ha esteso la mineralizzazione aurifera conosciuta di circa 200m lateralmente oltre i limiti precedenti, con 38 occorrenze separate di oro visibile identificate. Il foro ha raggiunto una profondità verticale di 850m e si è interrotto mentre era ancora all'interno dell'intrusione mineralizzata. Questo è il primo foro di perforazione a Gilt Creek dal 2007, quando il giacimento è stato delineato con 46 fori per un totale di 27.000 metri.
L'azienda prevede di incorporare Gilt Creek in una valutazione economica preliminare aggiornata (PEA) nel terzo trimestre del 2025, che dovrebbe migliorare significativamente il profilo di produzione e l'economia del progetto Omai Gold combinato. Il giacimento di Gilt Creek attualmente detiene risorse indicate di 1.151.000 once d'oro con una media di 3,22 g/t Au e risorse inferite di 665.000 once d'oro con una media di 3,35 g/t Au.

Toronto, Ontario--(Newsfile Corp. - February 24, 2025) - Omai Gold Mines Corp. (TSXV: OMG) (OTCQB: OMGGF) ("Omai" or the "Company") is pleased to announce assay results from the Company's first hole (24ODD-095) drilled at the Gilt Creek gold deposit - one of two orogenic gold deposits at its
Highlights from hole 24ODD-095 include:
- The extent of the gold mineralization stands out: the 774m length of the quartz diorite intrusion averaged 1.0 g/t Au1
- 2.00 g/t Au over 64.0m
- including 5.79 g/t Au over 9.0m
- and including 2.68 g/t Au over 12.5m
- 1.90 g/t Au over 48.0m
- including 4.19 g/t Au over 7.5m
- and including 2.47 g/t Au over 10.5m
- 2.14 g/t Au over 37.5m
- including 2.62 g/t Au over 24.2m
- 198.3m of the higher-grade intervals (not continuous) are over 1.5 g/t Au and give a weighted average grade of 2.78 g/t Au.
- Intersected mineralization first at a vertical depth of 225m within pyrrhotite-rich volcanics, assaying 2.0 g/t Au over 10.5m and 1.59 g/t Au over 7.5m below the diabase dike (Figure 2).
- Extended gold mineralization approximately 200m laterally to the southwest, to a vertical depth of 850m in an area with no prior drilling (Figure 2).
- 38 separate occurrences of visible gold between 442m and 1,139m (see Figure 4).
Elaine Ellingham, President & CEO, commented: "In addition to our recent drill results that show strong potential to expand the Wenot resource, the Gilt Creek underground deposit is a major growth lever at the Omai Gold Project. Core samples from this hole will be used to advance metallurgical test work, augmenting data from the historical production. This drilling also assists the underground mine design and planning to incorporate Gilt Creek into an updated PEA anticipated in Q3 of this year, which we expect will significantly enhance the production profile, mine life, and overall economics of the combined Omai Gold Project.
Hole 95 was the first drill hole completed at Gilt Creek since 2007. It successfully intersected a very significant 774m interval of the Gilt Creek intrusion, the majority of which hosts gold mineralization including 38 separate occurrences of visible gold. Additionally, the hole extends gold mineralization approximately 200m to the southwest beyond the current resource, where no prior drilling was done. This reinforces the immense geological potential of the Omai gold camp. With these very exciting results in hand, we are planning for a second Gilt Creek drill hole, which will continue to test the lateral and depth extents of gold mineralization."
All 774m of the Omai Stock drilled was sampled and 328 of the 538 samples or
The purpose of these new Gilt Creek drill holes is threefold: 1) to assist in mine planning and metallurgical studies that will facilitate inclusion of Gilt Creek into an updated Preliminary Economic Assessment ("PEA") mine plan anticipated in Q3 2025, 2) to test the lateral and depth extent of gold mineralization beyond that previously identified, and 3) to assist in the geological modelling of the Gilt Creek deposit in order to assess the overall exploration potential and extent of this very large Omai gold system.
The Company's April 2024 PEA3 included only the Wenot open pit deposit, which has been the focus of the 2024 and 2025 drill programs to date. Incorporating the Gilt Creek underground deposit into an expanded mine plan with the Wenot open pit deposit has the potential to significantly increase projected annual production rates and life of mine for the Omai project.
Hole 95 was drilled from the northern side of the historically mined Gilt Creek open pit, with an initial azimuth to the south aimed at drilling through the broad Gilt Creek gold resource2. The azimuth drifted further than expected to the west. The decision was made to continue the hole to explore the lateral limits of the intrusion in this area not previously drilled. The hole remained within the quartz diorite intrusive through to the final depth of 1,146m (-850m vertical depth). This confirms the intrusive extends at least 200m laterally beyond the previously known limit of the 2024 Resource3.
The hole encountered mafic volcanics (basalt) down to 118m, and as expected intersected the known diabase dike from 118m to 337m (true width approximately 150m). A minor interval of mafic volcanics, rich in pyrrhotite, was intersected below the dike from 337m to 372m. This unit hosts notable gold mineralization, with assays including 2.0 g/t Au over 10.5m and 1.59 g/t Au over 7.5m. The lower contact of the diabase is very passive (Figure 3), with no water pressure encountered during drilling throughout the hole.
The Omai intrusive complex was first encountered 372m downhole, first as a zone of hornblende diorite porphyry from 372m to 415m, a unit that intruded along the margins of the central Omai quartz dioritic to dioritic intrusive stock. The Omai intrusive stock extends from 372m through to the end of the hole at 1,146m, for a total of 774m of the favourable intrusion. It most likely continues beyond the end of the hole (Figure 2).
The Omai quartz diorite intrusion that hosts the Gilt Creek gold deposit is a roughly cylindrical body that intruded approximately 2.096 billion years ago ("bya") into an older sequence of volcanic rocks. Soon after, at about 2.094 bya, a coarse hornblende diorite porphyry intruded up along the flanks of the earlier intrusion.
This first drill hole completed into Gilt Creek since 2007 has proven very successful with most of the intrusion hosting gold mineralization. Hole 095 deviated from the planned path through the deposit and given the extensive mineralization encountered, is also encouraging for further expansion of the Gilt Creek resource.
Although the average grades in this hole are lower than the resource estimate3, the sheer extent of gold mineralization and the first confirmation that the intrusion extends beyond the known limits opens the door to potential expansion. Further, by applying the same cut-off grade of 1.5 g/t Au as was used in the resource estimate3 (established for a US
Gilt Creek Deposit Background
The Gilt Creek gold deposit is a large 500m by 275m compact, intrusion-hosted orogenic gold deposit. It is located approximately 500m north of the Wenot gold deposit on the Omai property (Figure 1). The Mineral Resource Estimate3 ("MRE") for Gilt Creek comprises Indicated Resources of 1,151,000 ounces gold averaging 3.22 g/t Au and Inferred Resources of 665,000 ounces gold averaging 3.35 g/t Au, using a 1.5 g/t Au cutoff and a US
The upper portion of this Gilt Creek gold deposit was open pit mined between 1993 and 20052, producing 2.4 million ounces averaging 1.5 g/t Au. Continuation of this deposit at depth was confirmed by IAMGOLD Corporation in 2006-2007 with 46 drill holes totalling approximately 27,000m. This drilling showed gold mineralization down to a depth of 967m below surface, although only sparse drilling was completed to that depth.
Significantly, approximately
Notably, all core drilled in 2006-2007 from the Gilt Creek deposit was sampled with
