Lakewood Exploration Announces Name Change to Silver Hammer Mining Corp. and Begins Trading on the Canadian Securities Exchange Under New Ticker Symbol "HAMR" Effective Friday, October 1, 2021

Overview

Even the most promising mining project can fail without the right management team in place. Statistics, surveys, and financial information are all important to consider, but it’s the management team that will take a promising mining project and transform it through the exploration, development and production stages as it progresses into a revenue-producing asset. That’s why one of the most important questions to ask when assessing a new company is: does the management team have a track record of success?

The right management team for any mining project will include professionals with a diverse background of technical, geological, business and financial experience. However, even a “dream team” of experts can fail to develop a valuable mine. That’s why many experts consider a proven track record of success to be the top factor in what makes a promising management team for a mining company.

Collective Mining Ltd. (TSXV:CNL) is a mineral exploration company focused on developing a portfolio of highly prospective gold, copper and molybdenum projects in Colombia. The company is led by the former management team of Continental Gold Inc — the same management team that sold the company for CA$2.0 billion (EV) after developing the largest gold mine in Colombia. Collective Mining currently holds an option to earn up to 100 percent interest on both of its projects with no underlying private royalties in one of the safest mining areas of Colombia.

Collective Mining’s team is highly specialized in identifying early-stage exploration projects with world-class potential. The company’s management team has an impressive track record of success, most notably identifying the potential of the Buriticá project and transforming it into a world-class gold mine. Continental Gold was the only pre-revenue company and the only mining company in Colombia to rank in the Social Investment Index, placing 11th in the country.

The company’s flagship Guayabales project is a high-grade gold, copper and molybdenum project. Collective Mining has announced a maiden 10,000 metre diamond drilling program underway to the northwest of Aris Gold’s (TSX:ARIS) Marmato gold mine, which contains proven and probable reserves of 2.0 million ounces gold and 4.35 million ounces silver (19.7 Mt grading 3.2 g/t gold and 6.9 g/t silver). The Guayabales project has never been systematically explored and the company strongly believes that the project has significant exploration upside. The Guayabales project is also located within 1 kilometre of the Marmato gold deposit which has an estimated resource of more than 10 million ounces of gold.

The company is led by internationally-recognized figures. Collective Mining’s executive vice president, Ana Milena Vásquez, was one of the top 100 Global Inspirational Women in Mining in 2020. Collective Mining is firmly committed to inclusion and diversity throughout its organization. Vásquez, as a leader in the Colombian mining sector, is well suited to promote this goal.

Collective Mining is strongly committed to an ESG model that focuses on implementing a collective mining framework. The company’s collective mining framework includes strengthening the mining supply chain, integrating with the local economy through alliances and developing the local community through a multi-pronged approach. Collective Mining’s team was also part of the best-in-class mining ESG program at Continental Gold that won multiple awards and high-level rankings of recognition.

The company is fully-funded with cash on hand to support its drill program through 2022.

Key Projects

Guayabales

The Guayabales project is a high-grade gold, copper and molybdenum project located in Caldas, Colombia. The project is situated 75 kilometres south of Medellin in the Marmato gold district. The property is strategically located adjacent to the Marmato gold mine along its strike. The project is located within 1 kilometre of the Marmato gold deposit which has an estimated resource of more than 10 million ounces of gold. Guayabales hosts a porphyry cluster that is connected to the Marmato orebodies by the Encanto Shear Zone.

The property has never been systematically explored. The project hosts five main targets including, Donut, the Box, Olympus, Victory and ME. The Donut target contains primary sulphide copper and gold while the Box target contains gold and silver found at the surface. The Olympus target features exposed copper, gold and molybdenum and the Victory target contains a porphyry-related magnetite stockwork system. Collective Mining has conducted drilling on the Donut target which returned, among other exciting results, a grassroots discovery of 104 metres at 1.3 g/t of gold equivalent.

The company has completed drilling the Donut target and has released some results, with the remiander to come through year-end 2021. Box drilling has commenced and initial results are expected early-2022. Drilling at the Olympus target has started and management intends to have a second rig turning in mid-December while the Victory target is slated for additional work and drilling beginning mid-2022. Collective Mining is also awaiting assay results from an extensive systematic channel sampling program. Going forward, the company is focused on generating new targets for the Guayabales project. The company strongly believes that the Guayabales project has significant exploration upside and holds the potential to become a world-class resource.

San Antonio

The San Antonio project is a gold, copper and molybdenum project located in the western margin of the Colombian Central Cordillera in Caldas, Colombia. The project is situated 70 kilometres south of Medellin and 8 kilometres northwest of the company’s Guayabales project. The project is located directly adjacent to the regional Romeral Fault system.

The San Antonio project has limited historical exploration focused solely on high-grade vein systems. The company began a drilling program on the property earlier in 2021. . Results revealed a grassroots discovery of 710 metres at 0.53 g/t of gold equivalent. Currently, the San Antonio project has three distinct porphyry-related targets, including Pound, COP and Dollar. The company has identified a high-grade soil anomaly of more than 100 ppb of gold and more than 6 ppm molybdenum.

The company is also currently in the process of defining the porphyry gold, copper and molybdenum system of significant dimensions. Collective Mining strongly believes that the sulphide hydrothermal breccia on the project has strong potential to host a porphyry system underneath the breccia.
