New Risk • May 06
New major risk - Share price stability The company's share price has been highly volatile over the past 3 months. It is more volatile than 90% of Canadian stocks, typically moving 19% a week. This is considered a major risk. Share price volatility increases the risk of potential losses in the short-term as the stock tends to have larger drops in price more frequently than other stocks. It may also indicate the stock is highly sensitive to market conditions or economic conditions rather than being sensitive to its own business performance, which may also be inconsistent. Currently, the following risks have been identified for the company: Major Risks Share price has been highly volatile over the past 3 months (19% average weekly change). Earnings have declined by 27% per year over the past 5 years. Revenue is less than US$1m. Minor Risks Shareholders have been diluted in the past year (25% increase in shares outstanding). Significant insider selling over the past 3 months (CA$1.0m sold). 공지 • Mar 23
GoldQuest Mining Corp. Reports New High-Grade Polymetallic Massive Sulphide Discovery At Cachimbo Target GoldQuest Mining Corp. announced results from the ongoing exploration campaign at the Cachimbo target. Drill hole TIR-26-58 has intersected a significant high-grade polymetallic zone, confirming a new mineralized parallel structure located to the northeast of the known Cachimbo mineralized zone. The intercept returned high-grade values for gold, silver, copper and zinc, with a notable high-grade core of 3.59 metres grading 17.63 g/t AuEq. This discovery represents the first major drill success at Cachimbo following the resumption of drilling after a nine-year hiatus and identifies a new target for additional drill testing. TIR-26-58: 12.26 m @ 2.52 g/t Au, 50.7 g/t Ag, 0.94% Cu & 12.0% Zn from 104.5 m depth. High-Grade Core: Including 3.59 m @ 5.74 g/t Au, 128.88 g/t Ag, 2.18% Cu, and 27.6% Zn. New Structure: The intercept confirms a new mineralized parallel structure, significantly expanding the potential footprint of the Cachimbo discovery. Open at Depth: Mineralization remains open in multiple directions, with further drilling planned to test the continuity of this new zone. Geophysics Program Underway: A Pole-Dipole Induced Polarization (PD-IP) survey is being executed to improve drill targeting. Hole TIR-26-58 was positioned to test a structural offset identified through recent detailed structural re-interpretation. The mineralization is hosted within a sequence of lithic and mafic tuffs, characterized by massive to semi-massive sulfide assemblages. The presence of high-grade copper (2.18% Cu) silver (128.88 g/t Ag) and zinc (27.61% Zn) within the core of this intercept confirms that the new parallel structure is a high-tenor polymetallic system. This second structure significantly expands the potential volume of the Cachimbo target, as it remains open along strike and down-dip. Table 1 below shows a detail of the intercepts and grades. Table 1: Results from hole TIR-26-58 HoleID From(m) To(m) Interval(m) Au g/t Cu % Ag g/t Pb % Zn % Au Eq g/t TIR-26-58 64.65 76.91 12.26 2.52 0.94 50.7 0.26 12.0 7.62 Includes 73.32 76.91 3.59 5.74 2.18 128.88 0.65 27.61 17.63 *Interval grades are calculated using uncapped assays. Gold values did not exceed 21.9 g/t which is below the capping level for Romero of 72.2 g/t. Intervals may not represent true widths. There is insufficient drilling to determine the exact orientation of the mineralized zones at this time. AuEq was calculated by using metal prices of Au USD 3,450/ounce, Cu USD 5.1/pound, Ag USD 37.4/ounce, Zn USD 3,280/ton and Pb USD 1,920/ton. No metal recoveries utilized. Exploration at Cachimbo is ongoing. While the initial results for TIR-26-58 are encouraging, assays for the second half of the hole remain pending and are expected shortly. Furthermore, drilling of holes TIR-26-57 and TIR-26-59, which targeted the down-dip extension of the primary Cachimbo zone, have been completed. Results from hole TIR-26-57 did not return significant intercepts, while results for hole TIR-26-59 are currently pending laboratory analysis. The rig has now transitioned to TIR-26-60, targeting deep extension of Cachimbo. In addition to the drilling, a new PD-IP survey is now being carried out. Two lines are already completed, and results shows a good correlation between low and high chargeability contrast and mineralization, especially at the newfound VMS structure. 공지 • Feb 27
