Toronto, Ontario--(Newsfile Corp. - February 26, 2021) - Xtierra Inc. (TSXV: XAG) ("Xtierra" or the "Company") is pleased to announce further positive and consistent drill results on another two drill holes of a five-hole program totaling 1800 meters into a previously identified structure (Victor vein) with high-grade silver mineralization located adjacent to and west of the main Bilbao Silver-Lead-Zinc deposit.
The objective of the third hole, X6B, was to test the continuity between the two best drill hole results from the 2010-2013 exploration work in which X26 intersected 6.0 meters of 847 Ag/t at 381 meters depth and X40-1 with 2.45 meters of 1623 Ag/t at 424 meters depth. Drill hole X6B was 459.05 meters in length with 97% core recovery and intersected six different levels of silver/base metal mineralization but exhibiting weaker mineralization southwest of X26, as follows:
Drill Hole | From (m) | To | Interval (m) | True Width (m) | Ag g/t | Pb% | Zn% | Cu% | Pb + Zn% | AgEq g/t |
X6B | 227.35 | 228.50 | 1.15 | 1.148 | 108 | 0.31 | 0.08 | 0.03 | 0.39 | 120 |

393.45 | 394.30 | 0.85 | 32 | 0.03 | 0.21 | 0.00 | 0.24 | 39 |
The objective of the fourth hole, X7B was to test the continuity between X5B at the northern end of the Victor vein structure and X6B. Drill hole X7B with a total depth of 308.7 meters a core recovery of 93% also intersected Silver and Lead, Zinc, Copper mineralization at two levels of elevation, as follows:
Drill Hole | From (m) | To | Interval (m) | True Width (m) | Ag g/t | Pb% | Zn% | Cu% | Pb + Zn% | AgEq g/t |
X7B | 139.20 | 140.05 | 0.85 | 0.76 | 56 | 0.05 | 0.09 | 0.01 | 0.14 | 60 |
265.85 | 278.85 | 13.00 | 9.37 | 61 | 5.50 | 4.41 | 0.08 | 9.91 | 336 | |

277.05 | 277.75 | 0.70 | 0.50 | 107 | 8.23 | 6.91 | 0.54 | 15.14 | 566 |
It is important to compare these drill results to the average grades of the resource estimate used in the preliminary economic assessment (PEA) of the main Bilbao deposit by Runge Pincock Minarco (Canada) Limited ("RPM") dated April 28, 2014. This independent Technical Report in accordance with NI 43-101 reported a resource estimate on the Bilbao Project with average grades of 2.1% zinc, 1.4% lead and 63.96 g/t silver, based on 3 year trailing average metal prices of: Zinc US$0.94/lb, Lead US$1.01/lb and Silver US$30.24/ounce. The mine plan incorporated in the PEA targeted the extraction of only the lower, unoxidized, sulphide zone based on a production rate of 2,000 tonnes per day, or 720,000 tonnes per year for a total of 5.2 million tonnes with over a mine life of approximately 8 years. Compared with the main Bilbao deposit, the current targeted mineralization is associated with a relatively narrow vein structure, possibly with skarn overtones.
Commenting on the results, Tim Gallagher, Company President said, "The drill results on the first four holes are consistent with our expectations and demonstrating the continuity of the mineralization within the Victor vein which should improve the economics of the Bilbao deposit, especially with the much-improved outlook for silver prices, approaching the US$30 per ounce level. We are waiting on analytical results on the fifth and final drill hole, X8B, which was drilled just north of the southernmost previous drill hole X100 which intersected 1 meter of 810 g/t Ag to test the extension of the Victor vein where it intersects a manto stockwork area, before determining next steps."
Drill core samples were sent to an SGS laboratory in Durango using the GE_ICP14B analytical method. Historically, samples from half-core were prepared at the Stewart Group laboratory in Zacatecas and analyzed for multi-element content using ICP-MS by Stewart Group in Kamloops, British Columbia. Standards and blanks were used regularly for quality control. Significant mineralized intervals are reported in the table as core lengths and estimated true thickness (70 to 95 per cent of core length).
